A shopkeeper purchases 220 items but pays only for 198 items at the marked price. He sells each item at a discount of 5%. Find his approximate gain percentage.

  1. 7%

  2. 10%

  3. 6%

  4. 11%

Answer: C

Solution

Solution: Let the marked price per item be 100. The total cost paid is \(198\times100=19800\). The selling price of 220 items after a 5% discount is \(220\times95=20900\). Profit \(=20900-19800=1100\). Gain percentage \(=\frac{1100}{19800}\times100\approx5.56\%\), approximately 6%. Trick: Assume a marked price of 100 per item to simplify the percentage calculations.
