A and B put in Rs.300 and Rs.400 respectively into a business. A reinvests into the business his share of the first year's profit of Rs.210 where as B does not. In what ratio should they divide the second year's profit?
Correct answer: A. 39:40
- A. 39:40
- B. 40:39
- C. 3:4
- D. 4:3
Explanation
The first year's profit is divided in the ratio 300:400 = 3:4, so A receives Rs.210 x 3/7 = Rs.90. In the second year, A's capital becomes Rs.300 + Rs.90 = Rs.390, while B's remains Rs.400, so the ratio is Rs.390:Rs.400 = 39:40. The likely mistake is option c, 3:4, which keeps using the original capitals after A reinvests his profit.
