The marked price of a radio is ₹ 480 . The shopkeeper allows a discount of 10 % and gains 8 % . If no discount is allowed, his gain percent would be
-
- 18 %
- 18.5 %
- 20.5 %
- 20 %
Correct Option: D
Here, MP = ₹ 480 , r = 10 % and R = 8 %
∴ CP = MP x (100 - r)/(100 + R)
= 480 x (100 - 10)/(100 + 8) = (480 x 90)/108 = ₹ 400
∴ Profit = 480 - 400 = ₹ 80
Hence, profit percent = (80/400) x 100 % = 20 %
