If 15 men can complete a work in 16 days. If 24 men are employed, then the time required to complete that work will be
We can measure the work in terms of man days. Since the same work is being done, number of man days should be constant. So,
Work done = Man-days = 15 × 16 = 24 × D, where D is the number of days.
⇨ D = (15 × 16) / 24 = 10 days
The correct option is C.
