Correct Answer: (5)
Solution: (5)
Ranjana’s present age $=15 x$ years
Rakhi’s present age $=17 x$ years
After 6 years,
$\frac{15 x+6}{17 x+6}=\frac{9}{10}$
$\Rightarrow 153 x+54=150 x+60$
$\Rightarrow 153 x-150 x=60-54$
$\Rightarrow 3 x=6 $
$\Rightarrow x=2$
$\therefore$ Ranjana’s age after 6 years $=15 x+6 =(15 \times 2+6)$ years $=36$ years
