5 men can do a piece of work in 7 days, working 5 hours daily. Find the time in which 10 men can do the same work, working 1.2 hours daily.

Correct Answer: 16 days
The total amount of work done = 5 * 7 * 5 = 175 units The number of men available = 10 The daily working hours = 1.2 hour Number of days taken = 175 / 12 = 15.58 days = 16 days
