A can do a work in 15 days. A and B together do the same work in 10 days. If they are paid ₹ 1500 for the work, how should the money be divided between A and B?
-
- 1000, 500
- 500, 1000
- 750, 750
- None of these
Correct Option: A
According to question ,
Work done by A = 15 days.
| A's one day work = | |
| 15 |
Work done by A and B together = 10 days
| ( A + B ) 's one day work = | |
| 10 |
Thus the ratio of efficiencies of ( A + B ) and A = 1/10 : 1/15 = 3 : 2
| ∴ A ’s share = | × 1500 = ₹ 500 | ||
| 3 |
| And B ’s share = | × 1500 = ₹ 1000 | ||
| 3 |
