Question
A gadget was obtained at Rs. 1000 and improved for Rs. 600.
It was marked 50% above the cost but later sold at a 10% loss. What is the discount given?Solution
ATQ,
Effective cost price of the gadget = 1000 + 600 = Rs. 1600
Marked price of the gadget = 1.5 × 1600 = Rs. 2400
Selling price of the gadget = 0.9 × 1600 = Rs. 1440
Therefore, discount offered = 2400 – 1440 = Rs. 960
