10 men working 6 hours a day can complete a work in 18 days.
so no. of man work hours needed to complete the work is = 10x6x18
so when 15 men work, and should complete the work in 12 days, let the no. of hours they work per day be h
so for the work to be completed the man work hours will be the same
so 15xhx12=10x6x18
so h=6
so they have to work for 6 hours a day to complete the work in 12 days
Ans:6
