Correct answer: (C) 21.05%
Selling '1 kg' but giving only 950 g means the trader charges 1.15 x (cost of 1000 g) while his actual cost is only for 950 g. Profit = 1150 - 950 = 200 on a cost of 950, giving a profit percentage of 200/950 x 100 = 21.05%.

सही उत्तर: (C) 20%
'1 किग्रा' बेचकर वास्तव में केवल 950 ग्राम देने का अर्थ है कि व्यापारी 1000 ग्राम की लागत का 1.15 गुना वसूलता है जबकि उसकी वास्तविक लागत केवल 950 ग्राम की है। लाभ = 1150 - 950 = 200, जो 950 की लागत पर 200/950 x 100 = 21.05% लाभ है।
