A dishonest shopkeeper professes to sell pulses at his cost price but uses a false weight of 950 gm for each kilogram. Find his gain percent. |
|
Answer» Let us consider the cost price of 1000gm pulses be Rs x Selling price of 950 gm pulses is also = Rs x Selling price of 1000 gm pulses = x/950 × 1000 So, Gain = SP – CP Gain = 1000x/950 – x = (1000x – 950x)/950 = 50x/950 Gain % = (gain/cost price) × 100 = (50x/950)/x × 100 = 50x/950x × 100 = 5/95 × 100 = 100/19 = 5 5/19% ∴ The Shopkeeper’s gain percent is 5 5/19%. |
