Question

a merchant cost price of an article is 80% of the advertise price . he also give two successive discount of 12% and 8% to a customer find his gain or loss percent

Answer 1

let the advertise price be 100.
cost price : 80
price after 1st discount : 100 - 12% of 100 = 88
price after 2ns discount : 88 x 0.92 = 80.96
hence profit percentage = (80.96-80)/80 x 100% = 1.2%
