Let the age of Shyam and Ram was x and 2x years respectively 20 years later from now.
∴Present age of Ram
= (2x — 20) years
and present age of Shyam = (x - 20) years
10 years ago. the age of Ram = 2x - 20 - 10 = 2x - 30
Age of Shyam = x - 20 - 10 = (x- 30) years
According to the question
$2\mathit{x}-30=5\left(\mathit{x}-30\right)$
⇒ $2\mathit{x}-30=5\mathit{x}-150$
=>$150-30=5\mathit{x}-2\mathit{x}$
⇒$3\mathit{x}=120$
$\therefore \mathit{x}=\frac{120}{3}=40$
∴ The present age of Shyam = 40 - 20 = 20 years
