Q72
ArithmeticPercentage, Profit & Loss
If the cost price of 120 mangoes is equal to the selling price of 110 mangoes, find the gain or loss percent.
- a.9%
- b.10%
- c.$11\frac{1}{9}$%
- d.$9\frac{1}{11}$%
Answer: (D) $9\frac{1}{11}$%
Selling 110 mangoes brings in what 120 cost, so on 110 mangoes the gain equals the cost of 10. Gain % = 10 ÷ 110 × 100 = $9\frac{1}{11}$%. 10% wrongly divides by 100, and $11\frac{1}{9}$% by 90.
