Solution:
First Case (work is done by 3 men or 6 boys)
2nd Case (work is done by 6 men and 8 boys)
Putt value of M from eq(1)
So, 6 men and 8 boys are equal to 20 boys;
Now if 1st case is taken with boys only, then 6 boys do the work in 20 days. In 2nd case now all men and boys are equal to 20 boys, so we can suppose that 20 boys can do the work in ‘x’ days.
We arrange data as below;
Solving for x;
So, 20 boys will finish the same work in 6 days
