A and B start a business jointly. A invests Rs.16000 for 8 months and B remains in the business for 4 months. Out of the total profit B claims 2/7th share. How much money is contributed by B?
Correct answer: B. Rs.12800
- A. Rs.10000
- B. Rs.12800
- C. Rs.6000
- D. Rs.8000
Explanation
B's share is 2/7, so A:B profit ratio is 5:2. A's investment-time is Rs. 16000 x 8 = Rs. 128000, hence B's is Rs. 128000 x 2/5 = Rs. 51200; since B invested for 4 months, his capital was Rs. 51200/4 = Rs. 12800. Option d results from dividing by the wrong number of months.
