Question

A shopkeeper offers 20 % discount to the customers and still makes a profit of 20 %. What is the cost price of a pair of shoes marked at Rs 1 , 800 ?

Answer 1

Answer:

The cost price is rupees 1182

Step-by-step explanation:

Discount = 1800 * 20/100 = 360

selling price = 1800 - 360 = 1440

Now, the shopkeeper still earns a profit of 20%

Therefore, Profit = 1440 * 20/100 = 288

So, cost price = 1440 - 288 = 1182

Answer 2

Step-by-step explanation:

A shopkeeper gets discount = 20%

Marked price = 1800

therefore, S.P. = MP - discount

1800 - [ 20/100 × 1800]

1800 - 360

1440

We have , S.P = 1440

Profit%= 20%

C.P = [ 100/100+profit%] × S.P

[100/100+20] × 1440

100/120 × 1440

1200

therefore CP = 1200
