Correct Answer: Rs. 250


Solution : Let the pocket money of the son before the increase be Rs. A

Pocket money after the increase of 20% = $A + (\frac{A × 20}{100})$

According to the given statement,
⇒ $A + (\frac{20A}{100})=300$
⇒ $\frac{100A+20A}{100}=300$
⇒ $\frac{120A}{100}=300$
⇒ $A = \frac{300×100}{120}$
⇒ A = 250

So, the pocket money of the son before the increase was Rs. 250. Hence, the first option is correct.
