Question

15 men take 10 days to complete a job working 12 hours a day how many hours a days should 10 men complete the job in 20 days​

Answer 1

PLEASE MARK MY ANSWERE AS BRAINLIST

When 10 men are required to complete the same job in 20 days working h hours a day, work done =10×20×h. But 10×20×h=15×10×12. Hence the number of hours for which they should work per day is 15×10×1210×20=9. ∴ 10 men can complete the work in 20 days working for 9 hours per day.

Answer 2

15×10×12 = 10×20× x

x = 15×10×12 divided by 10 × 20

x = 9 answer
