A contractor undertook to finish a work in 92 days and employed 110 men. After 48 days, he found that he had already done 3/5 part of the work, the number of men he can withdraw so that the work may still be finished in time is :
-
- 45
- 40
- 35
- 30
Correct Option: D
Using Rule 1,
| = | ||||
| W1 | W2 |
| ⇒ | = | |||||
| 5 | 5 |
⇒ M2 × 44 × 3 = 110 × 48 × 2
| ⇒ M2 = | = 80 | 44 × 3 |
∴ Number of men can be withdrawn
= 110 – 80 = 30
