Study the given graph and answer the questions that follows.

Degree wise distribution of no. of students working in Class (A, B, C, D and E):

Total no. of students = 3000

Find the difference between 124% of no. of students of class B and 136% of no. of students of class C?

53.4

⇒ No. of students in class B = (\frac{73.8}{360}\) × 3000 = 615

So, 124% of 615 = 762.6

⇒  No. of students in class C = \(\frac{72}{360}\) × 3000 = 600

So, 136% of class C = 136% of 600 = 816

⇒ Difference = 816 - 762.6 = 53.4
