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

According to the question,
Cost price of 6 litres milk $=$ Rs. 6
Cost price of 2 litres water $=$ Rs. 0
Total cost price of mixture $=6\mathit{x}$
Selling price of 6 litres milk and 2litres water $=8\times 2\mathit{x}$ $\Rightarrow 16\mathit{x}$
Profit $=$ Selling price $-$ Cost price
$\Rightarrow 16\mathit{x}-6\mathit{x}=10\mathit{x}$
Profit percent $=\left\{\left[\left(\mathit{S}\mathit{P}-\mathit{C}\mathit{P}\right)∕\mathit{C}\mathit{P}\right]\times 100\right\}$
$\Rightarrow \left(10\mathit{x}∕6\mathit{x}\right)\times 100=166.66\%$
$\therefore$ The profit percentage is $166.66\%$.
