Solution

Let current ages of Sonali and Monali are $$5x$$ and $$3x$$ years respectively.

According to ques,

=> $$\frac{5x+5}{3x+5}=\frac{10}{7}$$

=> $$35x+35=30x+50$$

=> $$35x-30x=50-35$$

=> $$5x=15$$

=> $$x=\frac{15}{5}=3$$

$$\therefore$$ Monali’s current age = $$3\times3=9$$ years

=> Ans - (A)
