Question

10 men can dig a well in 19 in how many days can 15 men did the same well

Answer 1

10 men dig the well in 9 days.

Let's the total work done by these men be one.

So if 10 men take 9 days then 10 men did 1/9 work each day.

Assuming efficiency for each man equal.

Therefore one man does 1/90 work each day.

So 15 men can do 15/90 work each day.

Let no of days taken by 15 men is x.

So, (15/90 )* x= 1

Therefore x = 6

So 15 men can dig well in 6 days.
