Question:
The marked price of a water cooler is Rs 4650. The shopkeeper offers an off-season discount of 18% on it. Find its selling price.
Solution:
Marked price $=$ Rs 4650 and discount $=18 \%$
Discount $=18 \%$ of marked price
$=18 \%$ of $R s 4650$
$=R s\left(4650 \times \frac{18}{100}\right)$
$=R s 837$
Selling price $=$ marked price $-$ discount
$=$ Rs $(4650-837)$
$=$ Rs 3813
Therefore, the selling price of the cooler is Rs 3813 .
