Question
A device was bought for Rs. 700 and repaired with Rs. 300.
The seller then increased its price by 30% over the cost and sold it at a 10% loss. What was the discount given?Solution
ATQ,
Effective cost price of the device = 700 + 300 = Rs. 1000
Marked price of the device = 1.3 × 1000 = Rs. 1300
Selling price of the device = 0.9 × 1000 = Rs. 900
Therefore, discount offered = 1300 – 900 = Rs. 400
