A shopkeeper allows 12% discount on the printed price of an article. What does a customer pay for the article marked at ₹ 150

The correct answer is ₹ 132

Marked Price = ₹ 150
% Discount = 12%
Discount = Discount % * Marked Price
Discount = 12% * 150 = 12/100 * 150 = 18
Price paid by the customer = 150 - 18 = ₹ 132
