Question

• A. 7 years
• B. 10 years
• C. 13 years

Answer 1

The correct option is B 10 years

Let Ravi's age be '$x$'.
Then three times his age is '$3x$'.
Ravi's mother is 3 years older than three times Ravi's age.
Then, Ravi's mother's age is '$3x+3$'.
Given, Ravi's mother is 33 years old.
$⟹3x+3=33$
$⟹3x=30$
$⟹x=10$
$\therefore$ Ravi's age is 10 years.
