24 men can complete 35% of the work in 20 days, working 2.5 hours daily. Find the number of days in which 10 men can do the remaining work, working 9 hours daily.

Correct Answer: 24.76 days
The total work done = 35% of the total work The work remaining = 65% of the total work The total work completed = 24 * 20 * 2.5 = 1200 units 1200 units is 35% of the work 65% of the work = 1200 / 35 * 65 = 2228.57 units The days to complete the work: 2228.57 / (10 * 9) = 24.76 days
