Explanation:

Let the man can finish the work in x days and the boy can finish the same work in y days.

Work done by one man in one day = 1/x .....(i)

and work done by one boy in one day = 1/y .....(ii)

On Multiplying eqn. (iii) by 2 and subtract eqn. (iv) from it

Hence, one man can finish it in 5 days and boy in 60 days
