A company showroom gives a discount of 20% on the second grade shoes and a further discount of 15% on shareholder’s coupon. The total discount, a coupon holder will get is
Let original price = $$100x$$
After 1st discount of 20% =>$$\frac{20}{100} * 100x = 20x$$
Price = $$100x-20x = 80x$$
After 2nd discount of 15% => $$\frac{15}{100} * 80x = 12x$$
Price will become = $$80x-12x = 68x$$
=> Equivalent Discount % = $$\frac{100x-68x}{100x}$$ * 100 = 32%
