A contractor undertakes to do a piece of work in 40 days. He engages 100 men at the begining and 100 more after 35 days and completes the work in stipulated time.
If he had not engaged the additional men, how many days behind schedule would it be finished?

- 7
- 18
- 12
- None
Correct Option: D
According to question , we have
[(100 × 35) + (200 × 5)] men can finish the work in 1 day.
4500 men can finish the work in 1 day.
| 100 men can finish work = | 4500 | = 45 days |
| 100 |
This is 45 - 40 = 5 days behind schedule.
