Question
A shopkeeper first allows a discount of 25% on a certain
variety of cloth and then further gives a discount of 20% to the person holding a shareholder’s coupon. The total discount received by a person holding a shareholder’s coupon would be:Solution
Let M.P = Rs 100 Total discounted price after allowing two discounts (25% & 20%) = Rs 100 × (100 - 25)/100 × (100 - 20)/100 = Rs 100 × 75/100 × 80/100 = Rs 60 Total discount = Rs 100 – 60 = Rs 40 Required discount % = 40/100 = 40%
