(B) Let the original price of sugar be $₹ x$ per $	ext{kg}$.The new price of sugar after a $10 \%$ decrease is $x - 0.10x = 0.9x$ per $	ext{kg}$.According to the problem,the difference in quantity purchased for $₹ 270$ at the original price and the new price is $1 	ext{ kg}$.$\frac{270}{0.9x} - \frac{270}{x} = 1$$\frac{300}{x} - \frac{270}{x} = 1$$\frac{30}{x} = 1$$x = 30$Therefore,the original price of sugar is $₹ 30$ per $	ext{kg}$.

When the price of sugar decreases by $10 \%$,a man can buy $1 \text{ kg}$ more for $₹ 270$. What is the original price of sugar per $\text{kg}$?
