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
If 40% of the students in Class E are transferred to Class A, then the difference between the no. of students in A and no. of students in C is:
Answer & explanation
Correct answer: option 4
⇒ No. of students in class E = \(\frac{93}{360}\) × 3000 = 775
⇒ 40% of E = \(\frac{2}{5}\) × 775 = 310
⇒ No. of students in class A = \(\frac{64.2}{360}\) × 3000 = 535
⇒ No. of students in class A after adding 40% of E = 535 + 310 = 845
⇒ No. of students in class C = \(\frac{72}{360}\) × 3000 = 600
Hence, The difference = 845 - 600 = 245
