If selling price of 75 articles is equal to cost price of 60 articles, then the approximate loss or gain percent is:
Let the cost price of 60 articles = C
Cost price of 1 article =Â $$\frac{C}{60}$$
Selling price of 75 articles = C
Selling price of 1 article =Â $$\frac{C}{75}$$
Loss% =Â $$\frac{\frac{C}{60}-\frac{C}{75}}{\frac{C}{60}}\times100$$
=Â $$\frac{\frac{5C-4C}{300}}{\frac{C}{60}}\times100$$
=Â $$\frac{60}{300}\times100$$
= 20%
Hence, the correct answer is Option D
