Apair of shoes with cost rupees 320 was sold at a loss of 5% what was the selling price if it is sold at profit of 20% find the gain percent if it were sold for rs360

Please see the answer below:

Step-by-step explanation:

1. Loss 5%

Cost = Rs.320

Loss % = 5% = 0.05

Sale Price = Rs.320 - (Rs.320 x 0.05) = Rs.320 - Rs.16 = Rs.304

2. Profit 20%

Cost = Rs.320

Profit % = 20% = 0.20

Sale Price = Rs.320 + (Rs.320 x 0.2) = Rs.320 + Rs.64 = Rs.384

3. Sold for Rs.360

Cost = Rs.320

Sale Price = Rs.360

Gain % = (Rs.360 - Rs.320) / Rs.320 = Rs.40 / Rs.320 = 0.125

or

Gain % = 12.5%
