## Show Answer

Solution(By Apex Team)

Sum of the present ages of A and B
= (18 × 2 + 4 × 2) years
= 44 years
Sum of the present ages of A, B and C
$\begin{array}{l}\text{= (24 × 3) years}\\
\text{= 72 years}\\
\text{C’s present age}\\
\text{= (72 – 44) years}\\
\text{= 28 years}\\
\text{∴ C’s age after 8 years}\\
\text{= (28 + 8) years}\\
\text{= 36 years}\end{array}$
