• A. $42$
• B. $48$
• C. $45$
• D. $50$

Answer 1

Answer: (C)

$45$

Let Ram's age be $x$ and son's age be $y$
Given, "$20$ years ago, Ram was five times as old as his son
" $=>x-20=5(y-20)=>x-5y=-80$ --- (1)
Also, " son will be $41$ years old 16 years after"
$=>y+16=41=>y=25$

Substituting $y=25$ in the
equation $\left(1\right)$, we get $x-5\left(25\right)=-80=>x=45$

Hence, Ram is $45$ years old.
