A shopkeeper marked a computer table for ₹7,200. He allows a discount of 10% on it and yet makes profit of 8%. What will be his gain percentage if he does NOT allow any discount?

20%

CP : MP = (100 – Discount) : (100 + Profit)

(100 – 10) : (100 + 8) = 90 : 108

CP = 90 and MP = 108

Profit =108 – 90 = 18

Profit percentage = \(\frac{18}{190}\) × 100 = 20%
