A dealer professes to sell his goods at cost price, but uses 900 gm weight for a kilogram. Find his profit percent.
Answer & explanation
Correct answer: option 2
If the shopkeeper used 900 grams weight instead of that means the cost price of the goods for the shopkeeper is 900 grams
So the profit % = (1000 - 900) × \(\frac{100}{900}\) = $11\frac{1}{9}$%
