Question
Ravi sold two items for Rs. 8,400 each. He gained 20% on
one item and incurred a loss of 20% on the other. What is the difference in their cost prices?Solution
ATQ,
Cost price of the item sold at 20% gain = 8400 ÷ 1.2 = Rs. 7,000
Cost price of the item sold at 20% loss = 8400 ÷ 0.8 = Rs. 10,500
So, required difference = 10500 - 7000 = Rs. 3,500
