Question 54

20% discount is offered on an item. By applying a promo code the customer wins 10% cash back. What is the effective discount?

Solution

Let the marked price of item = Rs. $$100x$$

Amount after 20 % discount = $$100x - \frac{20}{100} \times 100x$$

= $$100x - 20x = Rs. 80x$$

Selling price after 10 % cashback = $$80x - \frac{10}{100} \times 80x$$

= $$80x - 8x = Rs. 72x$$

=> Total discounted amount = $$100x - 72x = Rs. 28x$$

$$\therefore$$ Effective discount = $$\frac{28 x}{100 x} \times 100 =28 \%$$

=> Ans - (D)
