# What is her net gain/loss %?

Ritu had 400 mangoes. She sold 60 mangoes at 25% gain,120 mangoes at 10% gain and 140 mangoes at 20% loss. Her net gain/loss percent is:

1. 7.5%
2. 19/4%
3. 15/4%
4. None of these

Explanation:-

Let each mango cost her Rs. 100.

Then,  Cost Price  of 400 mangoes = 400  x 100 = Rs. 40,000

60 mangoes sold at 25% gain, then selling price of each mango,

= 100 + (25% of 100)= Rs. 125
Then,  selling price of 60 mangoes = 125 x 60 = Rs. 7,500

80 mangoes sold a 20% gain, selling price of 80 mangoes = (120 x 80) = Rs. 9,600

Selling price for 120 mangoes which are sold at 10% gain = (110  x 120) = Rs. 13,200

140 mangoes sold at 20% loss, then SP for each mango = 100 – (20% of 100) = 80 then,

Selling price for 140 mangoes = 140  x 80 = Rs. 11,200

Total money collected through selling mangoes = 7500 + 9600 +13200 + 11200 = 41,500
Gain = 41500 – 40000 = 1500

Then, percentage of  gain = (1500 * 100)/40000 = 15/4 % = 3(3/4)% = 3.75%

Hence, the correct answer is option (3) 15/4%
