A started a business with a capital of $ 1,00,000. One year later, B joined him with a capital of $ 2,00,000. At the end of 3 years from the start of the business, the profit earned was $ 84,000. The share of B in the profit exceeded the share of A by
-
- $ 10,000
- $ 12,000
- $ 14,000
- $ 15,000
Correct Option: B
Here , Total profit = $ 84,000
Total capitals of A for 36 months = $ 1,00,000 × 36 = $ 3600000
After 1 year , Total capitals of B for 24 months = $ 1,00,000 × 24 = $ 4800000
Ratio of equivalent capitals of A and B for 1 month = 3600000 : 4800000
Ratio of equivalent capitals of A and B for 1 month = 36 : 48 = 3 : 4
| Part of profit gained by A = | 7 |
| Part of profit gained by B = | 7 |
| ∴ Required difference = |  | 4 | - | 3 |  | × 84000 = $ 12000 | |
| 7 | 7 |
