Question 7

Rs 3200 is divided among A, B and C in the ratio of 3 : 5 : 8 respectively. What is the difference (in Rs) between the share of B and C?

Accepted Answer

Total ratio parts = 3+5+8 = 16, which equals Rs 3200. So, 1 part = Rs 200. The difference between B and C's share is (8-5) = 3 parts, which is 3 × 200 = Rs 600.
