What is the net discount (in %) for successive discounts of 10% and 20%?1). 232). 703). 754). 28

Answer»

Let the marked price be X

After giving FIRST discount, the cost will be = x - 0.1x = 0.9x

After giving SECOND discount, the cost will be = 0.9x - (0.9x × 20/100) = 0.72x

Discount = x - 0.72x = 0.28x

Hence, Discount % = 28%
