Ram is younger than Sarath by 7 years. If their ages are in the respective ratio of 7 : 9, how old is Sachin ?


A) 16 years

B) 18 years

C) 28 years

D) Cannot be determined

E) None of these

Answer:

Option E

Explanation:

Let Sarath age be $x$ years. Then, Ram's age $=(x-7)$ years.
$\therefore$ $\frac{x-7}{x}$ $=\frac{7}{9}$
$\Leftrightarrow 2x=63$
$\Leftrightarrow x = 31.5$.
Hence, Ram's age $=(x-7)$ $=24.5$ years.
