Q111
ArithmeticPercentage, Profit & Loss
A dishonest merchant professes to sell his goods at cost price, but used a weight of 900 grams for one kg. What is his profit percent?
- a.10%
- b.$11\frac{1}{9}$%
- c.$9\frac{1}{11}$%
- d.11%
Answer: (B) $11\frac{1}{9}$%
He gives 900 g but charges for 1000 g, gaining 100 g on every 900 g he actually sells. Profit % = 100 ÷ 900 × 100 = $11\frac{1}{9}$%. 10% wrongly divides by 1000 g.
