15 men can do a piece of work in 17 days, working 7.5 hours daily. Find the time in which 11 men can do the same work, working 2.1 hours daily.

Correct Answer: 88 days
The total amount of work done = 15 * 18 * 7.5 = 2025 units The number of men available = 11 The daily working hours = 2.1 hour Number of days taken = 2025 / (11 * 2.1) = 87.66 days

6 men can complete a piece of work in 12 days. 8 women can complete the same piece of work in 18 days whereas 18 children can complete the piece of work in 10 days. 4 men, 12 women and 20 children work together for 2 days. If only men were to complete the remaining work in 1 day how many men would be required totally?

18 men can complete a piece of work in 63 days. 9 women take 189 days to complete the same piece of work. How many days will 4 men, 9 women and 12 children together take to complete the piece of work if 7 children alone can complete the piece of work in 486 days ?

6 men can complete a piece of work in 12 days, 8 women can complete the same piece of work in 18 days and 18 children can do it in 10 days. 4 men, 12 women and 20 children do the work for 2 days. If the remaining work be completed by men only in 1 day, how many men will be required ?

The work done by a women in 8 hours is equal to the work done by a man in 6 hours and by a boy in 12 hours. If working 6 hours per day 9 men can complete a work in 6 days, then in how many days can 12 men, 12 women and 12 boys together finish the same work, working 8 hours per day ?

If 9 men working $${\text{7}}\frac{1}{2}$$ hours a day can finish a piece of work in 20 days, then how many days will be taken by 12 men, working 6 hours a day to finish the work ? (It is being given that 2 men of latter type work as much as 3 men of the former type.)

12 men can complete 35% of the work in 10 days, working 9 hours daily. Find the number of days in which 10 men can do the remaining work, working 5 hours daily.

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.

24 men can complete a piece of work in 18 days while 12 women can complete the same piece of work in 28 days. 27 men start working and are replaced by 14 women after 8 days. In how many days will 14 women finish the remaining work?
