Correct Answer: Rs. 5 per kg
Solution :
Let the initial price of the sugar be Rs. $x$ per kg.
Increase in price is 20%, it means increased price $=\frac{120x}{100}=\frac{6x}{5}$
According to the question,
Initial quantity – Current quantity = Reduction in quantity
⇒ $\frac{120}{x} -\frac{120}{ \frac{6x}{5}} = 4$
⇒ $\frac{120}{x} -\frac{600}{ {6x}} = 4$
⇒ $\frac{120}{x} -\frac{100}{ {x}} = 4$
⇒ $\frac{20}{x} = 4$
$\therefore x = 5$
Hence, the correct answer is Rs. 5 per kg.
