UGC NET Paper 1 GA 20 Nov 2021 Shift 2 Solved Paper

Let the selling price be Rs.100
Given, Cost price $=25\%$ of Selling price
Cost price $=\left(25∕100\right)\times 100=$ Rs. 25
Now, Profit $=$ Selling price $-$ Cost price $=100-25=\mathit{R}\mathit{s}.75$
Profit percentage $=($ Profit $∕$ Cost price $)\times 100$
Profit percentage $=\left(75∕25\right)\times 100=300\%$
$\therefore$ The profit percentage is $300\%$
