Question

A merchant gives a discount of 10% on face value, still he has a profit of 17% at the cost price, if he sells at face value, then what will be the percentage of profit

Answer 1

assume cost price is 100

face value = x

a discount of 10% on face value, still he has a profit of 17% at the cost price

so after 10% discount, sp = 100+17 = 117

this 117 is 90% of face value

so face value = 117 × 100/90 = 130

if sold at face value, profit = 130 - 100 = 30

profit = 30/100 × 100 = 30%
