If three successive discounts of 20%, 30% and 40% are given, then what will be the net discount (in percentage)?1). 802). 87.6 3). 904). 66.4

Answer»

LET MP be 100

SP after DISCOUNT = 100 × 80/100 × 70/100 × 60/100 = 33.6

We know, discount = MP – SP

So, net discount = 100 – 33.6 = 66.4

∴ Discount % = 66.4/100 × 100 = 66.4%
