Step-by-step explanation:

A man can do a work in 10 days

A man do a part of work in 1 days =$\dfrac{1}{10}$

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 = $\dfrac{1}{6} - \dfrac{1}{10}$

$⇒\dfrac{4}{60}$

➢So

Boy can do a part of work in 1 day =

$\dfrac{60}{14}$ $=15$

➣Then

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

$⇒15: \: 10$

$⇒3: \: 2$

➢Now

They got Rs.50 for that work

➣so

Boys share = $⇒\dfrac{2}{5} \times 50$

Boys share = 20

$\therefore Boys \: share \: is \: Rs.20$
