Miscellaneous Practice Problems

Question 1.
Sankari purchased 2$$\frac{1}{2}$$ m cloth to stitch a long skirt and 1$$\frac{3}{4}$$ m cloth to stitch blouse. If the cost is ₹ 120 per metre then find the cost of cloth purchased by her
Solution:
Cloth to stitch a long skirt = 2$$\frac{1}{2}$$ m
Cloth to stitch a blouse = 1$$\frac{3}{4}$$ m
Total length of the cloth = $$2 \frac{1}{2}+1 \frac{3}{4} m=2+\frac{1}{2}+1+\frac{3}{4}$$ m Cost of cloth purchased by Sankari = ₹ 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: Distance still he has to be walked = 3$$\frac{1}{4}$$ km Question 3.
Which is smaller? The difference between $$\frac{1}{2}$$ and 3$$\frac{2}{3}$$ or the sum of 1$$\frac{1}{2}$$ and 2$$\frac{1}{4}$$
Solution: Question 4.
Mangai bought 6$$\frac{3}{4}$$ kg of apples. If Kalai bought 1$$\frac{1}{2}$$ times as Mangai bought, then how many kilograms of apples did Kalai buy?
Solution:
Weight of apples Mangai bought = 6$$\frac{3}{4}$$ kg Weight of apples Kalai bought = 10$$\frac{1}{8}$$ kg

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:
Length of the staircase = 5$$\frac{1}{2}$$ m
Distance between each step = $$\frac{1}{4}$$ m
∴ Number of steps in the staircase = $$5 \frac{1}{2} \div \frac{1}{4}=\frac{11}{2} \div \frac{1}{4}=\frac{11}{2} \times \frac{4}{1}$$ = 22
There will be 22 steps in the staircase

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:   Question 8.
What fraction is to be subtracted from 9$$\frac{3}{7}$$ to get 3$$\frac{1}{5}$$ ?
Solution: 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: The other number is 2$$\frac{7}{12}$$ Question 10.
By what number should 3$$\frac{1}{16}$$ be multiplied to get 9$$\frac{3}{16}$$ ?
Solution: The number to be multiplied is 3.

Question 11.
Complete the fifth row in the Leibnitz triangle which is based on subtraction. Solution: Question 12.
A painted $$\frac{3}{8}$$ of the wall of which one third is painted in yellow colour. What fraction is the yellow colour of the entire wall. Solution: $$\frac{1}{8}$$ of the wall is painted yellow. 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, thenhow many jumps will it take to fetch its food? Solution:
Total distance to be covered by the rabbit = 26$$\frac{1}{4}$$m
Distance covered in one jump = 1$$\frac{3}{4}$$ m ∴ The rabbit jumps 15 times to fetch its food.
