Question
A gadget is marked 100% above its cost price and is sold
for Rs. 1,080 after giving two successive discounts of 10% and 20%, respectively. Find the difference between the marked price and the cost price of the gadget.Solution
ATQ Marked price of the gadget = {1080 / (0.90 × 0.80)} = Rs. 1,500 Cost price of the gadget = (1500 / 2) = Rs. 750 Required difference = 1500 – 750 = Rs.750
