Shopkeeper rise price by 33% and gives successive discount of 10% and 15%. What is overall % gain or loss?
[ "A)1.745%", "B)4.745%", "C)3.745%", "D)6.745%" ]
A
Let d initial price be 100 33 % rise now price = 133/100*100 = 133 10% discount Then price = 133 * 90/100 = 119.7 15 % discount Then price = 119.7 * 85/100 = 101.745 So Gain = 101.745 - 100 = 1.745 Gain % = Gain * 100 /CP ==> 1.745 * 100 /100 = 1.745% ANSWER:A
