Question

एक रुपया में 10 आम बेचने पर 50% का लाभ होता है, तो बताएँ
कि एक रुपया में कितने आम खरीदे गये थे ?​

Answer 1

Given :

10 mangoes in 1 Rs

Profit = 50%

To find :

How mangoes bought for 1 Rs.

Solution :

10 mangoes = 1 Rs

So, 1 mango = 1 / 10 Rs

Selling Price of 1 mango = 1 / 10 Rs

$ProfitPercentage = \frac{SP - CP}{CP} * 100$

$50 = \frac{\frac{1}{10}-CP }{CP}*100$

$CP = \frac{\frac{1}{10}-CP }{50} * 100$

$CP = (\frac{1}{10} - CP)*2$

CP = 1 / 5 - 2CP

CP + 2CP = 1 / 5

3CP = 1 / 5

CP = 1 / 15 Rs

Cost Price of 1 mango = 1 / 15 Rs

So, No. of mangoes bought for 1 Rs = 15

Therefore, 15 mangoes are bought of 1 Rs.
