The marked price of an article for sale is 20% of its cost price. How much percent does the dealer gain by allowing a discount of 15%?
Solution:
The marked price of an article for sale is 20% of its cost price.
Let the CP of the article be Rs. 100
Marked Price = 100 ×100/80 = 𝑅𝑠. 125
Then, SP after discount = 125 × 85/100 = Rs. 106.25
Gain Percent = (106.25 − 100/100) × 100 = 6.25%
6.25%
