• B. $60$ years
• C. $64$ years
• D. $50$ years

Answer 1

Answer: (C)

$64$ years

$\Rightarrow$ The ages of mother , son and daughter be 48 , 24 , 18 years respectively

$\Rightarrow$ Let age of father's age be $xyears.$

$\Rightarrow$ It is given, $\frac{Fathe{r}^{\prime }sage}{So{n}^{\prime }sage}=\frac{Mothe{r}^{\prime }sage}{Daughte{r}^{\prime }sage}$

$\therefore$ $\frac{x}{24}=\frac{48}{18}$

$\therefore$ $x=\frac{48}{18}\times 24$

$\therefore$ $x=64years.$

$\therefore$ The age of father is $64years$.
