Question

mangoes are bought at 10 per100 the rate per 100 at which they must be sold that the gain 100 may be equal to the selling price of 250 mangoes

Answer 1

In Rs. 10 mangoes can be bought = 100In Rs. 100 mangoes can be bought = 1000
If the fruit merchant sold 1000 mangoes, he would gain equal to the selling price of 250 mangoes.
Now, Let Selling price of 1 mango be Rs 'x'Therefore, Gain = 250xGain = Selling Price - Cost Price250x = 1000x - 100250x - 1000x = - 100-750x = - 100x = 100/750x = 2/15So, selling price of 1 mango is Rs. 2/15
Therefore, selling price of 100 mangoes = 2*100/15= 200/15= Rs.40/3
