Question

The market price of a Mobile phone 8,000.A shopkeeper sells it at a discount of 20% and earn a profit 25%.find the cost price of the mobile.?

Answer 1

Market Price - Discount @ 20%(marked price) - 25%(cost price) = Cost price

Rs.8000 - 20%(Rs.8000) - 25%(cost price) = cost price

8000 - 1600 = Cost price + 25%( cost price)

Rs.6,400 = 1.25 cost price

cost price = 6400/ 1.25

Cost price of the mobile phone is Rs.5,120
