Kamal can do a work in 15 days. Bimal is 50 per cent more efficient than Kamal in doing the work. In how many days will Bimal do that work?
-
- 14 days
- 12 days
- 10 days
-
10 1 days 2
Correct Option: C
Using Rule 15,
Efficiency and time taken are inversely proportional Bimal : Kamal = 150 : 100 (work)
⇒ 100 : 150 (Time) = 2 : 3
∵ 3 units ⇒ 15 days
| ∴ 2 units | × 2 = 10 | 3 |
Hence, Bimal complete the work in 10 days
