1. Ram's son's age is $\frac{1}{3}$ of Ram's wife's age. Ram's wife's age is $\frac{4}{5}$ of Ram's age and Ram's age is $\frac{3}{5}$ of Ram's father's age. Find the age of Ram's son, if Ram's father is 50 years old ?

A. 6 years

B. 8 years

C. 10 years

D. 12 years

Solution:

\begin{aligned} Ram's father's age \\ =  50 years, \\ Ram's age \\ = (\frac{3}{5} \times 50) years \\ =  30 years \\ Ram's wife's age \\ = (\frac{4}{5} \times 30) years \\ =  24 years \\ Ram's son's age \\ = (\frac{1}{3} \times 24) years \\ =  8 years \end{aligned}
