Question

Age of my mother is $6$ years more than $3$ times my age.If my age is $12$ years then my mother's age is :

• A. $54$
• B. $42$
• C. $30$
• D. $36$

Answer 1

The correct option is B

$42$

Age of mine = $x$.

Age of my mother = $3x+6$.

If $x=12$, $3x+6$ becomes $(3\times 12)+6$ = $42$.

Hence Option B is Correct.
