Shashi buys an old refrigerator for ₹12,000 and spends ₹1,000 on its repairs. If he sells the refrigerator for ₹15,000, then his gain percentage is:

Correct option is C

Given:
Buying price of refrigerator = ₹12,000
Repair cost = ₹1,000
Selling price = ₹15,000
Formula Used:
​$$\text{Gain} = \left( \frac{\text{Selling Price} - \text{Total Cost Price}}{\text{Total Cost Price}} \right) \times 100$$​​
Solution:
Total cost = Buying price + Repair cost = ₹12,000 + ₹1,000 = ₹13,000
=> Gain = $$\frac{2000}{13000} \times 100 = \frac{200}{13} \% = 15 \frac{5}{13} \% \\$$​​
