(B) Let the original price of sugar be $P$ per quintal.Total money available $= 18 	imes P$.The new price after a $10 \%$ fall is $P - 0.10P = 0.90P$.Let $x$ be the quantity of sugar that can be bought with the same total money at the new price.Then,$x 	imes 0.90P = 18 	imes P$.$x = \frac{18 	imes P}{0.90P} = \frac{18}{0.9} = 20$.Therefore,$20$ quintals can be bought at the lower price.

The price of sugar has fallen by $10 \%$. How many quintals can be bought for the same money which was sufficient to buy $18$ quintals at the higher price?
