Question
Arjun sold two items for Rs. 990 each, one at 10% profit
and other at 10% loss. Determine his overall profit/loss % from the whole transactionSolution
ATQ,
Cost price of the items that was sold at 10% profit = 990 ÷ 1.10 = Rs. 900
Cost price of the items that was sold at 10% loss = 990 ÷ 0.90 = Rs. 1,100
Total cost price of both items = 900 + 1100 = Rs. 2,000
Total selling price of both the items = 990 + 990 = Rs. 1980
Total loss = 2000 – 1980 = Rs. 20
% loss = (20/2000) × 100 = 1%
