Miscellaneous Practice Problems

Question 1.

Sankari purchased 2\(\frac{1}{2}\) m cloth to stich a long skirt and 1\(\frac{3}{4}\) m cloth to stitch blouse. If the cost is Rs. 120 per metre then find the cost of cloth purchased by her.

Solution:

Total cloth purchased

cost of 1 metre = Rs. 120

Total cost of cloth purchased

= Rs. 120 × \(\frac{17}{4}\)

= Rs. 510

Question 2.

From his office, a person wants to reach his house on foot which is at a distance of 5\(\frac{3}{4}\) km. If he had walked 2\(\frac{1}{2}\) km, how much distance still he has to walk to reach his house?

Solution:

Question 3.

Which is smaller? The difference between 2\(\frac{1}{2}\) and 3\(\frac{2}{3}\) or the sum of 1\(\frac{1}{2}\) and 2\(\frac{1}{4}\).

Solution:

∴ The difference of 2\(\frac{1}{2}\) and 3\(\frac{2}{3}\) is smaller

Question 4.

Mangai bought 6\(\frac{3}{4}\) kg of apples. If Kalai 1 bought 1\(\frac{1}{2}\) times a Mangai bought, then how many kilograms of apples did Kalai buy?

Solution:

Apples bought by Mangai = 6\(\frac{3}{4}\) kg

Apples bought by Kalai

Question 5.

The length of the staircase is 5\(\frac{1}{2}\) m. If one step is set at \(\frac{1}{4}\) m, then how many steps will be there in the staircase?

Solution:

Total length of the staircase = 5\(\frac{1}{2}\) m

length of each step = \(\frac{1}{4}\) m

No of steps in the stair case

= 22 steps

Challenge Problems

Question 6.

By using the following clues, find who am I?

(i) Each of my numerator and denominator is a single-digit number.

(ii) The sum of my numerator and denominator is a multiple of 3.

(iii) The product of my numerator and denominator is a multiple of 4.

Solution:

The numerator may be any one of!, 2, 3,4, 5, 6, 7, 8, 9 and the denominator may be any one of 1, 2,3,4, 5,6, 7,8,9. Sum of numerator and denominator is a multiple of 3.

∴ Possible proper fractions are \(\frac{1}{2}, \frac{1}{5}, \frac{1}{8}, \frac{2}{4}, \frac{2}{7}, \frac{3}{6}, \frac{3}{9}, \frac{4}{5}, \frac{4}{8}, \frac{5}{7}, \frac{6}{9}\)

Also given the product of numerator and denominator is a multiple of 4.

∴ Possible fractions are \(\frac{1}{8}, \frac{2}{4}, \frac{4}{5}, \frac{4}{8}\)

Question 7.

Add the difference between 1\(\frac{1}{3}\) and 3\(\frac{1}{6}\) and the difference between 4\(\frac{1}{6}\) and 2\(\frac{1}{3}\)

Solution:

Adding Difference

Question 8.

Solution:

Let the fraction be x

According to the problem

The fraction to be subtracted is 6\(\frac{8}{35}\)

Question 9.

The sum of two fractions is 5\(\frac{3}{9}\). If one of the fractions is 2\(\frac{3}{4}\), find the other fraction.

Solution:

Let the other fraction be x

According to the problem,

∴ The other fraction is 2\(\frac{7}{12}\)

Question 10.

By what number should 3\(\frac{1}{16}\) be multiplied to get 9\(\frac{3}{16}\)?

Solution:

Let the number be x

According to the problem,

x = 3

The number is 3

yellow colour of the entire wall

= \(\frac{3}{8}\) × \(\frac{1}{3}\)

= \(\frac{1}{8}\)

Question 13.

A rabbit has to cover 26\(\frac{1}{4}\) m to fetch its food. If it covers 1\(\frac{3}{4}\) m in one jump, then how many jumps will it take to fetch its food?

Solution:

Total distance = 26\(\frac{1}{4}\) m

Distance covered in one jump = 1\(\frac{3}{4}\) m

Number of jumps required to fetch the food
