A contractor undertook to do a piece of work in 9 days. He employed a certain number of laborious but 6 of them being absent from the very first day, the rest could finish the work in 15 days. Find the number of men originally employed.
-
- 15
- 6
- 13
- 9
Correct Option: A
Let the number of men originally employed = x
So, (x - 6) men could finish the work in 15 days and x men could finish the work in 9 days.
∴ 9x = 15(x - 6)
⇒ x = 15
