The marked price of a pen is 25% more than its cost price. The pen is sold for ₹220 after a discounr of ₹30. What is the profit percentage?

10%

Let the cost price of the article = 100

Then according to the question the marked price = 125 ( 25% more than CP)

Discount = 30

Selling price = 220

Marked price = Selling price + Discount = 220 + 30 = 250

So, 125x = 250

100x = CP = 200

Profit% = ( 220 - 200 ) × \(\frac{100}{200}\) = 10%
