A contractor undertook to finish a certain work in 124 days and employed 120 men. After 64 days, he found that he had already done 2/3 of the work.
How many men can be discharged now so that the work may finish in time ?
-
- 48
- 56
- 40
- 50
Correct Option: B
Using Rule 1,
| Remaining work = 1 - | = | |||
| 3 | 3 |
Remaining days = 124–64= 60
| ∴ | = | |||
| W1 | W2 |
| ⇒ | = | |||||
| 3 | 3 |
| ⇒ M2 = | = 64 | 2 × 60 |
∴ No. of men can be discharged
= 120 – 64 = 56 men
