A man undertakes to do a certain work in 150 days. He employs 200 men. He finds that only a quarter of the work is done in 50 days. The number of additional men that should be appointed so that the whole work will be finished in time is :
-
- 75
- 100
- 125
- 50
Correct Option: B
Using Rule 1,
| 200 men do | work in 50 days. | 4 |
| ∴ | = | |||
| W1 | W2 |
| ⇒ | = | |||||
| 4 | 4 |
⇒ M2 × 100 = 200 × 50 × 3
⇒ M2 = 300
∴ Additional men = 100
