Question
A trader buys an item for Rs. 6,400 and marks it 75%
above the cost price. He then gives a flat discount of Rs. 'd' and another 20% off. If he earns a profit of 10%, calculate the value of 'd'.Solution
ATQ,
Marked price of the item = 1.75 × 6,400 = Rs. 11,200 Price after first discount = Rs. (11,200 - d) Selling price of the item = 1.10 × 6,400 = Rs. 7,040 So, 0.80 × (11,200 - d) = 7,040 Or, 8,960 - 0.80d = 7,040 Or, 0.80d = 1,920 Or, 'd' = Rs. 2,400
