Example 1:
The market price of an article is $18,000. By selling it at a discount of 20% the loss is 4% find its cost price.
Solution:
Market price = $18,000 and discount = 20%
Therefore, Selling price = M.P(100 - d%) / 100
= 18,000 (100 - 20) / 100
= 18,000 * 80 / 100
Selling price = 14,400
Selling price = $14,400 and loss = 4%
Therefore, Cost price = (Selling price * 100) / (100 - l%)
= (14,400 * 100) / (100-4)
= 1,440,000 / 96
Cost price = $15,000

Example 2:
Jake wants to buy a skateboard. The regular price of the board is $135. Suppose it is on sale at a 25% discount. Find the sale price of the skateboard.
Let d represent discount.
d = 0.25(135) = 33.75
Selling price = 135 - 33.75 = 101.25
