Question

Three men can do a piece of work in 4 days. How many men can finish it in 3 days? ​

Answer 1

Answer:

4 men are needed to finish the work in 3 days.

Step-by-step explanation:

3 men take 4 days to finish a work

total would be 3 men * 4 days = 12 'man days'

Let 3 men take x days to do the same work

so total would be 3 men * x days = 3x 'man days'

since the work is the same therefore the total 'man days' in both cases should be equal.

Thus 12 man days = 3x man days

or 12 man days / 3 man days = x

or 4 = x
