Show Answer
Correct Answer: (5)
Solution: (5)
Simi’s present age $=x$ years
$\therefore$ Raju’s present age $=(x-4)$ years
$\therefore$ Ganga’s present age $=(x+2)$ years
According to the question,
$\frac{x+8}{x+4}=\frac{10}{9}$
$\Rightarrow 10 x+40=9 x+72$
$\Rightarrow 10 x-9 x=72-40$
$\Rightarrow x=32$
$\therefore$ Raju’s present age $=(32-4)$ years $=28$ years
