The answer to this question is 30

Answer 2

Answer:

Boy's share is rs.20

Step-by-step explanation:

A man can do a work in 10 days

A man do a part of work in 1 day= $\frac{1}{10}$

With the help of a boy he can do the same Work in 6 days.

Together they can do a part of work in 1 day = $\frac{1}{6}$

So, Boy can do a part of work in 1 day = $\frac{1}{6}-\frac{1}{10} =\frac{4}{60}$

So, Boy van do complete work in days = $\frac{60}{4}=15$

So, Man : Boy = $\frac{1}{10}:\frac{1}{15}$

                       = $15:10$

                       = $3:2$

They get rs.50 for that work.

So, Boys share = $\frac{2}{5} \times 50$

Boys share =20

So, Boy's share is rs.20
