Question 5.
Write about the types of markets and their functions.
Answer:
On the Basis of Geographic Location:

1. Local Markets: In such a market the buyers and sellers are limited to the local region or area.
2. Regional Markets: These markets cover a wider are than local markets like a district, or a cluster of few smaller states
3. National Market: This is when the demand for the goods is limited to one specific country. Or the government may not allow the trade of such goods outside national boundaries.
4. International Market: When the demand for the product is international and the goods are also traded internationally in bulk quantities, we call it an international market.

On the Basis of Time:

1. Very Short Period Market: This is when the supply of the goods is fixed, and so it cannot be changed instantaneously. For example the market for flowers, vegetables. Fruits etc.
2. Short Period Market: The market is slightly longer than the previous one. Here the supply can be slightly adjusted. Example: The demand of fish, milk or egg,
3. Long Period Market: Here the supply can be changed easily by scaling production. So it can change according to the demand of the market.

On the Basis of Nature of Transaction

1. Spot Market: This is where spot transactions occur, that is the money is paid immediately. There is no system of credit.
2. Future Market: This is where the transactions are credit transactions. There is a promise to pay the consideration sometime in the future.

On the Basis of Regulation:

1. Regulated Market: In such a market there is some oversight by appropriate government authorities. For example, the stock market is a highly regulated market.
2. Unregulated Market: This is an absolutely free market. There is no oversight or regulation, the market forces decide everything.

On the basis of Nature of competition:

1. Monopoly: Monopoly refers to a market structure in which there is a single producer or seller that has control over the entire market. This single seller deals in products that have no close substitutes.
2. Monopolistic Competition: Monopolistic competition refers to a market situation in which there are a large number of buyers and sellers of products.

Answer:

Question 4.
Solve log ₄ 2 ^8x = 2 ^log₂8
Answer:
Given log ₄ 2^8x = 2 ^log₂8
log ₄ 2^8x = 2^log₂23
log ₄ 2^8x = 2^{3 log₂2}
log ₄ 2^8x = 2³ = 8
2^8x = 4⁸
(2²)^4x = 4⁸
⇒ (4)^4x = 4⁸
⇒ 4x = 8
⇒ x = \(\frac { 8 }{ 4 }\) = 2

Question 5.
If a² + b² = 7ab, show that
log \(\left(\frac{a+b}{3}\right)\) = \(\frac{1}{2}\) (log a + log b)
Answer:
Given
a² + b² = 7ab
Adding both sides 2ab we get
a² + b² + 2ab = 7ab + 2ab
(a + b)² = 9ab

Taking square root on both sides

Taking logarithm on both sides

(1) 1
(2) 2
(3) 0
(4) 4
Answer:
(2) 2

Explanation:
Given quadratic equation is
2x² + (a – 3) x + 3a – 5 = 0
Let the roots be α, β
Sum of the roots α + β = \(-\frac{(a-3)}{2}\)
Product of the roots α β = \(\frac{3 a-5}{2}\)
Given α + β = α β
∴ \(-\frac{(a-3)}{2}=\frac{3 a-5}{2}\)
– a + 3 = 3a – 5
3a + a = 5 + 3
4a = 8 ⇒ a = 2

Question 12.
If a and b are the roots of the equation x² – kx +16 = 0 and satisfy a² + b² = 3², then the value of k is
(1) 10
(2) – 8
(3) – 8, 8
(4) 6
Answer:
(3) – 8, 8

Explanation:
a + b = k ….(1) ab = 16 ….(2)
a² + b² = (a + b)² – 2ab = 32 .
k² – 32 = 32 ⇒ k² = 64 ⇒ k = ±8

Question 13.
The number of solutions of x² + |x – 1| = 1 is
(1) 1
(2) 0
(3) 2
(4) 3
Answer:
(3) 2

Explanation:
The given quadratic equatiuon is
x² + |x – 1| = 1 ——– (1)

Case(i)
By the definition of mod function if x – 1 ≥ 0, then
|x – 1| = x – 1
∴ (1) ⇒ x² + x – 1 = 1
x² + x – 2 = 0
x² + 2x – x – 2 = 0
x(x + 2) – 1 (x + 2) = 0
(x – 1)(x + 2) = 0
x – 1 = 0 or x + 2 = 0
x = 1 or x = – 2
Since x – 1 ≥ 0
x = – 2 is not possible. ∴ x = 1

Case (ii)
Again by the definition of mod function if x – 1 < 0 then
|x – 1| = – (x – 1)
∴ (1) ⇒ x² – (x – 1) = 1
x² – x + 1 = 1
x² – x = 0
x (x – 1 ) = 0
x = 0 or x – 1 = 0
x = 0 or x = 1
Since x < 1, x = 1 is not possible
∴ x = 0
∴ The required solution set is {0, 1}
Number of solutions = 2

Question 14.
The equation whose roots are numerically equal but opposite in sign to the roots of 3x² – 5x – 7 = 0 is
(1) 3x² – 5x – 7 = 0
(2) 3x² + 5x – 7 = 0
(3) 3x² – 5x + 7 = 0
(4) 3x² + x – 7 = 0
Answer:
(2) 3x² + 5x – 7 = 0

Explanation:
The given quadratic equation is
3x² – 5x – 7 = 0 ——— (1)
Let α and β be the roots of eqn (1)
Sum of the roots α + β = \(-\left(\frac{-5}{3}\right)\)
α + β = \(\frac{5}{3}\)
Product of the roots α β = – \(\frac{7}{3}\)
The quadratic equation whose roots are – α and – β is
x² – (sum of the roots) x + Product of the roots = 0
x² – (- α – β)x + (- α)(- β) = 0
x² + (α + β)x + αβ = 0
x² + \(\frac{5}{3}\) x – \(\frac{7}{3}\) = 0
3x² + 5x – 7 = 0 is the required equation.

Question 15.
If 8 and 2 are the roots of x² + ax + c = 0 and 3, 3 are the roots of x² + dx + b = 0 , then the roots of the equation x² + ax + b = 0 are
(1) 1, 2
(2) -1, 1
(3) 9, 1
(4) -1, 2
Answer:
(3) 9, 1

Explanation:
Given that 8 and 2 are the roots of the equation
x² + ax + c = 0 ———- (1)
Sum of the roots 8 + 2 = \(-\frac{a}{1}\) ⇒ a = -10
Product of the roots 8 × 2 = \(\frac{c}{1}\) ⇒ c = 16
Also given 3 , 3 are the roots of
x² + dx + b = 0 ——— (2)
Sum of the roots 3 + 3 = – \(\frac{d}{1}\) ⇒ d = – 6
Product of the roots 3 × 3 = \(\frac{b}{1}\) ⇒ b = 9
Let a and p be roots of the equation x² + ax + b = 0
Sum of the roots α + β = – y
α + β = -(-10)
α + β = 10 ——– (3)
Product of the roots α β = y
α β = 9 ———- (4)
(α – β) = (α + β)² – 4αβ
= 10² – 4 × 9
= 100 – 36 = 64
α – β = 8 ——— (5)
Solving equations (3) and (5)

Substituting in equation (3),
9 + β = 10
⇒ β = 10 – 9 = 1
∴ The required roots are 9, 1

Question 16.
If a and b are the real roots of the equation x² – kx + c = 0 , then the distance between the
points(a, 0) and (b, 0)is
(1) \(\sqrt{\mathbf{k}^{2}-4 \mathbf{c}}\)
(2) \(\sqrt{4 k^{2}-c}\)

(4) \(\sqrt{\mathbf{k}-8 \mathbf{c}}\)
Answer:
(1) \(\sqrt{\mathbf{k}^{2}-4 \mathbf{c}}\)

Explanation:
Given that a and b are the roots of the equation
x² – kx + c = 0 ——— (1)
Sum of the roots a + b = \(-\frac{(-k)}{1}\)
a + b = k ———- (2)
Product of the roots ab = \(\frac{c}{1}\)
ab = c ——– (3)
Distance between the points ( a, 0) and (b, 0) is

Question 17.
If then the value of k is
(1) 1
(2) 2
(3) 3
(4) 4
Answer:
(3) 3

Explanation:

kx = 2x – 2 + x + 2
kx = 3x ⇒ k = 3

Question 18.
If , then the value of A + B is
(1) – \(\frac{1}{2}\)
(2) – \(\frac{2}{3}\)
(3) \(\frac{1}{2}\)
(4) \(\frac{2}{3}\)
Answer:
(1) – \(\frac{1}{2}\)

Explanation:

1 – 2x = A (x + 1) + B(3 – x) ——— (1)
Put x = – 1 in equation (1)
1 – 2 (- 1) = A (- 1 + 1) + B (3 + 1)
1 + 2 = 0 + 4B ⇒ B = \(\frac{3}{4}\)
Put x = 3 in equation (1)
1 – 2 × 3 = A(3 + 1) + B(3 – 3)
1 – 6 = 4A + 0
– 5 = 4A

Tamilnadu Samacheer Kalvi 11th Maths Solutions Chapter 2 Basic Algebra Ex 2.10

Determine the region in the plane determined by the inequalities

Question 1.
x ≤ 3y, x ≥ y
Answer:
Consider the line x = 3y
When y = 0 ⇒ x = 0
When y = 1 ⇒ x = 3
When y = – 1 ⇒ x = – 3

Consider the line x = y
When x = 0 ⇒ y = o
When x = 1 ⇒ y = 1
When x = – 1 ⇒ y = – 1

To find the region of x ≤ 3y: The line x = 3y divides the cartesian plane into two half planes. Consider the point (1,1) this point satisfies the inequality x < 3y. This point (1,1) lies above the line x = 3y.

Hence all points satisfying the inequality lie above the line x = 3y.

Therefore x < 3y represents the upper half plane of the Cartesian plane bounded by the line x = 3y. Since x ≤ 3y, this region also contains all the points on the straight line x = 3y.

To find the region x ≥ y: The line x = y divides the cartesian plane into two half planes. Consider the point (2,1). This point (2,1) satisfies the inequality x > y and this point (2,1) lies below the line x = y. ∴ All points satisfying the inequality x > y will lie below the line x = y. Therefore x > y represents the lower half plane of the cartesian plane bounded by the line x = y. Since x > y this region also contains all the points on the straight line x = y.

The required region is the region common to the regions x ≤ 3y and x ≥ y

Question 2.
y ≥ 2x, – 2x + 3y ≤ 6
Answer:
Consider the straight line y = 2x
When x = 0 ⇒ y = 2 × 0 = 0
When x = 0 ⇒ y = 2 × 1 = 2
When x = – 1 ⇒ y = 2 × – 1 = – 2

Consider the line – 2x + 3y = 6
When x = 0 ⇒ – 2 × 0 + 3y = 6 ⇒ 3y = 6 ⇒ y = 2
When y = 0 ⇒ – 2x + 3 × 0 = 6 ⇒ -2x = 6 ⇒ x = – 3

To find the region of y ≥ 2x: The straight line y = 2x divides the cartesian plane into two half planes. Consider the point (1, 3) satisfying the inequality y > 2x. This point (1, 3) lies above the straight line y = 2x. ∴ All points satisfying the inequality y > 2x will lie above the line y = 2x.

To find the region of -2x + 3y ≤ 6:
The straight line – 2x + 3y = 6 divides the cartesian plane into two half planes one half plane contains the origin and the other half plane does not contain the origin.

Substitute the origin (0, 0) in the inequality – 2x + 3y < 6
we get – 2 × 0 + 3 × 0 < 6 ⇒ 0 < 6
∴ (0,0) satisfies the inequality – 2x + 3y < 6
∴ The inequality – 2x + 3y < 6 represents the half plane containing the origin. Since – 2x + 3y ≤ 6, this region contains all the points on the straight line – 2x + 3y = 6.

The required region is the region common to y ≥ 2x and – 2x + 3y ≤ 6

Question 3.
3x + 5y ≥ 45, x ≥ 0, y ≥ 0
Answer:
Consider the line 3x + 5y = 45
when x = 0, 3 × 0 + 5y = 45 ⇒ y = \(\frac{45}{5}\) = 9
when y = 0, 3x + 5 × 0 = 45 ⇒ x = \(\frac{45}{3}\) = 15

To find the region of x ≥ 0, y ≥ 0:
x ≥ 0 and y ≥ 0 denote the first quadrant of the Cartesian plane.
Since x ≥ 0 and y ≥ 0 this region contains all the points on the lines x = 0 and y = 0.

To find the region of 3x + 5y ≥ 45: The straight-line 3x + 5y = 45 divides the cartesian plane into two half-planes, one-half plane containing the origin and the other half-plane does not contain the origin.

Substitute the origin (0,0) in the inequality 3x + 5y > 45 we get 3 × 0 + 5 × 0 > 45 ⇒ 0 > 45 which is impossible. Therefore, (0, 0) does not satisfy the inequality 3x + 5y > 45 represents the half plane that does not contain the origin bounded by the straight line 3x + 5y = 45. Since 3x + 5y ≥ 45, x ≥ 0, y ≥ 0, this region contains all the points on the straight lines 3x + 5y = 45.

∴ The required region is the common region bounded by x ≥ 0, y ≥ 0, and 3x + 5y ≥ 45.

Question 4.
2x + 3y ≤ 35, y ≥ 2, x ≥ 5.
Answer:
Consider the straight line 2x + 3y = 35
When x = 0, 2 × 0 + 3y = 35 ⇒ \(\frac{35}{3}\)
When y = 0, 2x + 3 × 0 = 35 ⇒ \(\frac{35}{2}\)

To find the region of 2x + 3y ≤ 35: The straight-line 2x + 3y = 35 divides the cartesian plane into two half-planes, one-half plane contains the origin and the other half-plane does not contain the origin.

Substitute the origin (0, 0) in the inequality 2x + 3y < 35, we get 2 × 0 + 3 × 0 < 35 ⇒ 0 < 35. (0, 0) satisfies the inequality.

Therefore, the inequality 2x + 3y < 35 represents the half plane that contains the origin (0, 0) bounded by the straight line 2x + 3y = 35. Since 2x + 3y ≤ 35, this region contains all the points on the straight line 2x + 3y = 35.

To find the region y ≥ 2: The straight line y = 2 divides the cartesian plane into two half-planes, one-half plane contains the origin and the other half-plane does not contain the origin. Substitute the point (0, 0) in the inequality y ≥ 2 we get 0 >2 which is impossible. Hence (0, 0) does not satisfy the inequality y > 2.

∴ The inequality y > 2 represents the half-plane that does not contain the origin bounded by the straight line y = 2. Since y ≥ 2, this region contains all the points on the straight line y = 2.

To find the region x ≥ 5: The straight line x – 5 divides the cartesian plane into two half-planes, one half-plane containing the origin and the other half-plane does not contain the origin.

Substitute the origin (0,0) in the inequality x > 5 we get 0 > 5 which is impossible. Hence (0, 0) does not satisfy the inequality x > 5.

∴ The inequality x > 5 represents the half-plane that does not contain the origin bounded the straight line x = 5.
Since x ≥ 5, this region contains all the points on the straight line x = 5

∴ The required region is the common region bounded by 2x + 3y ≤ 35, y ≥ 2, x ≥ 5.

Question 5.
2x + 3y ≤ 6, x + 4y ≤ 4, x ≥ 0, y ≥ 0
Answer:
Consider the straight line 2x + 3y = 6
When x = 0, 2 × 0 + 3y = 6 ⇒ y = \(\frac{6}{3}\) = 2
When y = 0, 2x + 3 × 0 = 6 ⇒ x = \(\frac{6}{2}\) = 3

Consider the straight line x + 4y = 4
When x = 0 ⇒ 0 + 4y = 4 ⇒ y = \(\frac{4}{4}\) = 1
When y = 0 ⇒ x + 4 × 0 = 4 ⇒ x = 4

To find the region of 2x + 3y ≤ 6: The straight line 2x + 3y = 6 divides the cartesian plane into two half planes, one half plane contains the origin and the other half plane does not contain the origin. Substitute the origin (0, 0) in the inequality 2x + 3y < 6 we get 2 × 0 + 3 × 0 < 6 ⇒ 0 < 6

∴ The origin (0,0) satisfies the inequality 2x + 3y < 6. Hence the inequality 2x + 3y < 6 represents the half plane that contains the origin (0, 0). Since 2x + 3y ≤ 6, this region contains all the points on the straight line 2x + 3y = 6.

To find the region of x + 4y ≤ 4 : The straight line x + 4y = 4 divides the cartesian plane into two half planes, one half plane contains the origin and the other half plane does not contain the origin. Substitute the origin (0, 0) in the inequality x + 4y < 4, we get 0 + 4 × 0 < 4 ⇒ 0 < 4.

Therefore the origin (0, 0) satisfies the inequality x + 4y < 4. Therefore the inequality x + 4y < 4 represents the half-plane that contains the origin bounded by the line x + 4y = 4. Since x + 4y ≤ 4, this region contains all the points on the straight line.

To find the region x ≥ 0, y ≥ 0: x ≥ 0 and y ≥ 0 denote the first quadrant of the cartesian plane.
Since x ≥ 0 and y ≥ 0 this region contains all the points on the lines x = 0 and y = 0.

The required region is the common region bounded by 2x + 3y ≤ 6, x + 4y ≤ 4, x ≥ 0 and y ≥ 0.

Question 6.
x – 2y ≥ 0 , 2x – y ≤ – 2 , x ≥ 0, y ≥ 0
Answer:
Consider the straight line x – 2y = 0
When x = 0
⇒ -2y = 0
⇒ y = 0

When x = 2
⇒ 2 – 2y = 0
⇒ 2y = 2
⇒ y = 1

When x = -2
⇒ – 2 – 2y = 0
⇒ -2y = 2
⇒ y = – 1

Consider the line 2x – y = – 2
When x = 0 ⇒ – y = – 2 ⇒ y = 2
When y = 0 ⇒ 2x – 0 = – 2 ⇒ x = – 1

To find the region of x – 2y ≥ 0: The straight line x – 2y = 0 divides the cartesian plane into two half-planes. Consider the point (3,1) satisfying the inequality x > 2y. The point (3, 1) lies below the straight line x = 2y in the cartesian plane.

∴ All the points satisfying the inequality x > 2y will lie in the half-plane below the straight line x = 2y. Since x ≥ 2y this region contains all the points on the straight line x = 2y.

To find the region of 2x – y ≤ – 2:
-(2x – y) ≥ 2 ⇒ – 2x + y ≥ 2
Consider the straight line – 2x + y = 2. This line divides the cartesian plane in to two half planes, one half plane contains the origin and the other half plane does not contain the origin. Substitute the origin (0, 0) in the inequality – 2x + y > 2 we get- 2 × 0 + 0 > 2 ⇒ 0 > 2 which is impossible. Therefore (0, 0) does not satisfy the inequality -2x + y > 2. Hence the inequality -2x + y > 2 represents the half plane that does not contain the origin bounded by the straight line. Since -2x + y > 2, this region contains all the points on the straight line -2x + y = 2

To find the region of x ≥ 0, y ≥ 0: x ≥ 0 and y ≥ 0 denote the first quadrant of the cartesian plane. Since x ≥ 0 and y ≥ 0 this region contains all the points on the lines x = 0 and y = 0.

∴ The required region is the region common to x – 2y ≥ 0 , 2x – y ≤ – 2 , x ≥ 0, y ≥ 0.

Question 7.
2x + y ≥ 8, x + 2y ≥ 8, x + y ≤ 6
Answer:
Consider the straight line 2x + y = 8
When x = 0 ⇒ 2 × 0 + y = 8 ⇒ y = 8
When y = 0 ⇒ 2x + 0 = 8 ⇒ x = \(\frac{8}{2}\) = 4

Consider the straight line x + 2y = 8
When x = 0 ⇒ 0 + 2y = 8 ⇒ y = \(\frac{8}{2}\) = 4
When y = 0 ⇒ x + 2 × 0 = 8 ⇒ x = 8

Consider the straight line x + y = 6
When x = 0 ⇒ 0 + y = 6 ⇒ y = 6
When y = 0 ⇒ x + 0 = 6 ⇒ x = 6

To find the region of 2x + y ≥ 8: The straight-line 2x + y = 8 divides the cartesian plane into two half-planes one half plane contains the origin and the other half plane does not contain the origin. Substitute the origin (0, 0) in the inequality 2x + y > 8 we get 2 × 0 + 0 > 8 ⇒ 0 > 8 which is impossible.
∴ The origin (0, 0) does not satisfy the inequality 2x + y > 8. Hence the inequality 2x + y > 8 represents the half plane that does not contain the origin bounded by the straight line 2x + y = 8. Since 2x + y ≥ 8, this region contains all the points on the straight line 2x + y = 8.

To find the region of x + 2y ≥ 8: The straight line x + 2y = 8 divides the cartesian plane into two half planes, one half plane contains the origin and the other half plane doesnot contain the origin. Substitute the origin (0, 0) in the inequality x + 2y > 8 we get 0 + 2 × 0 > 8 ⇒ 0 > 8 which is impossible. ∴ The origin (0, 0) does not satisfy the inequality x + 2y > 8. Therefore, the inequality x + 2y > 8 represents the half plane that does not contain the origin bounded by the straight line x + 2y = 8. Since x + 2y ≥ 8 this region contains all the points on the straight line x + 2y = 8.

To find the region of x + y ≤ 6: The straight line x + y = 6 divides the cartesian plane into two half-planes, one half-plane contains the origin and the other half-plane does not contain the origin. Substitute the origin (0, 0) in the inequality x + y < 6 we get 0 + 0 < 6 ⇒ 0 < 6 which is true.
∴ The origin (0, 0) satisfies the inequality x + y < 6. Hence, the inequality x + y < 6 represents the half plane that contains the origin bounded by the straight line x + y = 6. Since x + y ≤ 6, this region contains all the points on the straight line x + y = 6.

Thus the required region is the region common to 2x + y ≥ 8, x + 2y ≥ 8, x + y ≤ 6

The Seven Seeds Summary in English and Tamil

Long ago, there was a kingdom at the foothills of Anaimalai. The kingdom flourished in trade and arts under the rule of their king’s rule. He was respected and revered by all. It has been thirty years under his rule now. One day, the ageing king woke up worried. He was getting very old and had no heir to take his place. He decided to adopt and raise a child as the heir, but he knew that the adopted child must be honest.

வெகு காலத்திற்கு முன்னர், ஆனைமலையின் அடிவாரத்தில் ஒரு ராஜ்ஜியம் இருந்தது. அரசரின்ஆட்சியில் அந்த ராஜ்ஜியம் வியாபாரத்திலும் கலைகளிலும் செழித்தது. அந்த அரசர் அனைவராலும் மதிக்கப்பட்டு, மரியாதையும் செய்யப்பட்டார். அவர் அரசாள ஆரம்பித்து முப்பதுவருடங்களாகிவிட்டன. வயதான அந்த அரசர் ஒருநாள் கவலையுடன் எழுந்தார்அவருக்கு வயதாகிக் கொண்டே போவதாலும், வாரிசுகள் இல்லாததாலும் ஒரு குழந்தையை வாரிசாக தத்தெடுத்து வளர்க்க எண்ணினார். ஆனால் தத்தெடுக்கப்படும் குழந்தை நேர்மையாக இருக்க வேண்டும் என்பதும் அவருக்கு தெரியும்.

To find the child, he held a competition in his kingdom that was open to all. The competition had many levels and spanned for nearly six months. At the end of it, five boys and five girls made it to the very last round. There seemed little to separate them; each one of them was intelligent, strong and capable.

சரியான குழந்தையை கண்டுபிடிப்பதற்காக, எல்லாரும் பங்கேற்கக்கூடிய ஒரு போட்டியை அவர் நடத்தினார்.அந்த போட்டி, பல நிலைகளை கொண்டதாகவும், ஆறு மாதங்களுக்கு நீண்டதாகவும் இருந்தது. அதன் முடிவில், ஐந்து சிறுமிகளும், ஐந்து சிறுவர்களும் கடைசி சுற்றுக்கு தேர்வு பெற்றனர். ஒவ்வொருவரும் புத்திசாலியாகவும், வலிமையானவராகவும், தகுதிபெற்றவராகவும் இருந்ததால், தேர்ந்தெடுப்பது மிகவும் சிரமமாக இருந்தது.

The kina said, “I have one last test for you all. The one who passes this test will be the winner. As you all know the winner will be the heir to my throne.” He continued, “Our kingdom depends on agriculture, so the new leader must know how to grow plants. Here are seven seeds of wheat for each of you. Take them home. Plant and nurture them for six weeks. At the end of the sixth week, we shall see who has done the best job of nurturing them. That person will be the heir to the throne.”

“உங்கள் அனைவருக்கும் ஒரு கடைசி பரீட்சை உள்ளது, இதில் வெல்பவரே வெற்றியாளர் ஆவார்” எனக் கூறிய அரசர், “அவரே என் அரியணைக்குவாரிசு” என்றும் கூறினார். மேலும் “நம் ராஜ்ஜியம் விவசாயத்தை நம்பியுள்ளது, எனவே புதிய தலைவர்பயிர்களை பற்றியும்) வளர்ப்பது பற்றியும் தெரிந்திருக்க வேண்டும்” என்றார். “உங்கள் அனைவருக்கும் ஏழு கோதுமை விதைகளை அளிக்கிறேன். அவற்றை வீட்டிற்கு எடுத்துச் சென்று, நட்டு ஆறு வாரங்கள்பராமரிக்க வேண்டும். ஆறு வாரங்களின் முடிவில், யார்சரியாக அவற்றை வளர்த்து பராமரிக்கிறாரோ அவரே அரியணைக்கு வாரிசாவார்” என்றார்.

The children took their seeds and hurried home. They all got a pot, prepared some soil and sowed their seeds. The entire kingdom was excited. They were all anxious to see who the next king would be.

குழந்தைகள் விதைகளை எடுத்துக் கொண்டு வீட்டிற்குவிரைந்தனர். அனைவரும் ஒரு தொட்டியை எடுத்து,சிறிது மண்ணை இட்டு, விதைகளை விதைத்தனர். தமது அடுத்த அரசர் யார் என அறிய மொத்த ராஜ்ஜியமும் ஆவலாக இருந்தது.

One of the finalists was Ani. The days stretched into weeks. but the seeds failed to sprout. Ani didn’t know what had gone wrong. Ani and her parents were heartbroken. She had selected the soil with care, put the right manure, and very dutifully watered it. She had even prayed over it, day and night, and yet her seeds hadn’t grown at all.

ஓர் இல்லத்தில், அனி என்ற சிறுமியும் அவளுடைய பெற்றோரும் மனமுடைந்து இருந்தனர்.நாட்கள், வாரங்களாக நீண்டன. ஆயினும், விதைகள் முளைக்கவில்லை. தவறு எங்கே நேர்ந்ததென, அனி; க்கும் புரியவில்லை . ஏனெனில், சரியானபடி மண்ணை தேர்ந்தெடுத்து, சரியான உரத்தையும் இட்டு, கடமை தவறாது நீரை ஊற்றியும் வந்தாள். அவள் இரவும், பகலுமாக பிரார்த்தனை செய்து வந்தும்அவளுடைய விதைகள் வளரவே இல்லை .

Some of her friends advised her to go and buy new seeds from the market and plant. After all, they said, “How can anyone tell if they were the same seeds?”Ani’s parents had always taught her the value of honesty. They reminded her that if the king wanted them to plant just any wheat, he would have asked them to get their seed.

அவளுடைய சில நண்பர்கள் கடைவீதிக்கு சென்று புதிய விதைகளை வாங்கி பயிரிடும்படி கூறினர். ஏனெனில் யாராலும் விதைகளை குறிப்பாக அது, இது எனகண்டுபிடிக்க இயலாது. அனியின் பெற்றோர் அவளிடம் நேர்மையின் மதிப்பை பற்றி அவளுக்கு போதித்து இருந்தனர்.

“If you use anything different from what the king gave, that would be dishonest. I Maybe you’re not destined for the throne. If so, let it be, but it would be wrong to cheat the king,” they told her. Ani agreed.

அவர்கள் அனியிடம் “குழந்தைகள் ஏதாவது ஒரு கோதுமையைபயிரிடட்டும் என அரசர் நினைத்திருந்தால், அவர், விதைகளை நீங்களே ஏற்பாடு செய்து கொள்ளுங்கள் என்று கூறியிருப்பாரே” என்பதையும் அவளுக்கு நினைவுபடுத்தினர். “அவர் அளித்த விதைகளுக்கு மாறாக, வேறு ஒன்றை உபயோகப்படுத்தினால் அது நேர்மையற்ற செயலாகிவிடும். அரியணைக்கு நீ தேர்வாகாவிட்டாலும் பரவாயில்லை, ஆனால் அரசரை ஏமாற்றுவது தவறாகும்” என அவர்கள் கூற, அனியும்அதை ஏற்றுக்கொண்டாள்.

It had been six weeks now. The muchawaited day had come. The children returned to the palace, each of them proudly carrying a pot of healthy seedlings. It was obvious that the other nine had great success with their seeds.

ஆறு வாரங்களும் முடிந்துவிட்டன. எதிர்பார்க்கப்பட்ட நாளும் வந்தது. குழந்தைகள் அனைவரும்அரண்மனைக்கு திரும்பினர். ஒவ்வொருவரும் கையில் ஆரோக்கியமான பயிர்களை, தொட்டியில் வைத்திருந்தனர். இதன் மூலம் (அனியைத் தவிர மற்ற ஒன்பது பேரும் தங்கள் விதைகளை நடவு செய்வதில் வெற்றியடைந்திருந்தனர்.

The king arrived. He was beaming looking at the children and their pot of healthy seedlings. He began walking along the line of pots the children had kept. He asked each of them, “Is this what grew from the seeds I gave you?” And each of them responded, “Yes, your majesty.” And the king would nod and move down the line.

அவைக்கு வந்த அரசர், குழந்தைகளின் தொட்டிகளில் ஆரோக்கியமான பயிர்கள் இருப்பதை கண்டு புன்னகைசெய்தார்! குழந்தைகள் வரிசையாக வைத்திருந்த தொட்டிகளை பார்வையிட்டவர், ஒவ்வொருவரிடமும் “நான் கொடுத்த விதைகளிலிருந்தா இவை வளர்ந்தன?” என்று கேட்டார். ஒவ்வொருவரும் “ஆம், மாட்சிமை பொருந்திய அரசே” என கூறவும், அரசர் தலையசைத்து சென்றார்.

The king finally got to the last one, Ani. The girl was shaking. She feared that the king might have thrown her into prison for wasting his precious seeds. “What did you do with the seeds I gave you?” the king asked. “Your majesty, I planted them and cared for them every day. I am sorry but, they failed to sprout,” Ani said. She hung her head in shame. “Boo!” jeered the crowd.

கடைசியாக இருந்த அனியிடம் அரசர் சென்றார். அந்த சிறுமி நடுங்கிக் கொண்டிருந்தாள். அரசர்கொடுத்தமதிப்புமிக்க விதைகளை வீணாக்கிவிட்டதற்காக, ” தன்னை அரசர் சிறையில் போட்டுவிடுவாரோ என அவள் பயந்தாள். “நான் கொடுத்த விதைகளை நீ என்ன செய்தாய்?” என அரசர் அவளிடம் கேட்டார். “மாட்சிமை பொருந்திய அரசரே, நானும் விதைகளை பயிரிட்டு தினமும் பராமரித்தேன். ஆனாலும் அவை முளைக்கவில்லை என்பதற்காக வருந்துகிறேன்” என்று அனி கூறிவிட்டு தலையை கவிழ்த்துக் கொண்டாள்.கூடியிருந்த கூட்டமும் அதற்கு தன் அதிருப்தியைக் காட்டியது.

But the king raisedhis hands and signalled for silence. Then he said “Dear people behold my heir. The next leader of our kingdom!” The people were confused, “Why that girl? How can she be the right choice?”

தன் கைகளை உயர்த்தி கூட்டத்தினரை அமைதியாக இருக்கும்படி சைகை காட்டிய அரசர், அன்பு மக்களே,இதோ நம் இராஜ்ஜியத்தின் அடுத்த தலைவர்” எனக் கூற மக்கள் குழப்பமடைந்தனர். “யார் இவளா? எப்படி இவள் சரியான தேர்வாக ஆனாள்?” எனக் குழம்பினர்.

The king took his place on his throne with Ani by his side and said, ‘I aave each of them, seven seeds. This test was not for growing wheat. It was a test of character, a test of honesty. If a leader must have one quality, it must be that he or she should be honest. People should be able to trust the leader. Only this girl passed the test. I gave boiled seeds and boiled seeds cannot grow.”

தன் ஆசனத்தில் அமர்ந்த அரசர், அனியை தன் அருகில் அமர்த்திக்கொண்டு இவ்வாறு கூறினார். “நான்ஒவ்வொருவருக்கும் ஏழு விதைகளை கொடுத்தேன். இது கோதுமை விளைவிப்பதற்கான போட்டியல்ல. இது குணத்திற்கும், நேர்மைக்குமான பரீட்லைகுணத்திற்கும், நேர்மைக்குமான பரீட்சையாகும். ஒரு தலைவர் யாராக இருப்பினும் அவருக்கு வேண்டிய தகுதி, அவர் நேர்மையானவராக இருக்க வேண்டும்என்பதே. மக்கள் நம்பும்படியாக தலைவர் இருக்க வேண்டும். அந்த தேர்வில் இந்த சிறுமியே தேறினாள். நான் (அவர்கள் அனைவருக்கும்) கொடுத்தது, வேகவைத்த விதைகள். அவை எவ்வாறு வளரும்?”.
