Answer 1

Let the present age of grandson be x

Given, age of grandfather is ten times than grandon. So his age will be 10x

Given, grandfather is 54 years older than grandson, age will be 10x - 5


According to the question,

10 - 54 = x

10x - x = 54

9x = 54

x = $\dfrac{54}{9}$

x = 6


Age of son => x => $\boxed{6\:years}$

Age of grandfather => 10x => 10 × 6 => $\boxed{60\:years}$



$\therefore{}$ The age of grandfather and grandson are 60 and 6 years respectively.
