Question 25 Profit Loss Discount and Value Added Tax Exercise 13.2
A lady shopkeeper allows her customers 10% discount on the marked price ofthe goods and still gets a profit of 25%. What is the cost price of a fan for her marked at Rs. 1250?
Answer:
Given,
MP of the fan = Rs 1250
Profit = 25%
Discount = 10%
Discount allowed = 10/100 × 1250
= Rs 125
So, SP of the shoes = (1250 - 125) = Rs 1125
By using the formula,
CP = 100/(100 + gain%) × SP
= 100/(100 + 25) × 1125
= 100/125 × 1125
= Rs 900
∴ Cost price of the fan is Rs 900
