Answer 1

Heya

Here goes your answer

20 men can do the work in 40 days

The work they do in one day is 1/40

40 men can do the work in ? days

The work 40 men do in one day= the work 20 men do in one day+ the work the left over 20 men can do in one day = 1/40+1/40

1/40 + 1/40 = 2/40 = 1/20

40 men can do the work in 20 days
