Question

If 10 men can finish a job in 8 days, then the number of men required to complete the job in half day is

Answer 1

8 days = 10 men

1 day = 10/8 men

½ day = 10/8 × ½

= 5/8

Answer 2

If 10 men can complete a work in 8 days so in one day 80 men will be required. So for half day 160 men will be required. So if you see, the work done is constant. Therefore x=160 men.
