A dishonest shopkeeper sells goods at cost price but uses a false weight of 900 grams in place of 1 kg. Find his profit percentage.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 11.11%
The customer pays for 1000 g but receives 900 g. The shopkeeper’s profit is the 100 g kept back, taken on the 900 g he actually gives.
Weight given \(=900\) g, weight paid for \(=1000\) g
Gain \(=1000-900=100\) g
Profit % \(\displaystyle =\frac{100}{900}\times100=11\frac{1}{9}\%=11.11\%\)
His profit is 11.11%.
