(b) In a class of 45 students, 60% are boys. Find the number of boys in the category.
Solution:
Total students = 45
% of boys = 60%

Number of boys in the class is 27. (c) In an orchard of 400 trees, 35% are mango trees. 42% were apple trees and the rest were grape vines. How many grape vines are there?
Solution:
Total trees = 400
% of mango trees = 35%
% of apple trees = 42%
% of grape vines = (100 – 35 + 42)%
= (100 – 77)%
= 23%
Number of grape vines = 23% of 400
= $$\frac{23}{100}$$ × 400
= 92
92 grape vines are there.

(d) Mr Mahesh earns ₹ 7,200 per month. He spends 33$$\frac{1}{3}$$% on food. Find the amount spent on food.
