Madhya Pradesh Police Exam Model Paper 8

Given∶
Loss = 6%
Formula used∶
Selling price = cost price – loss
Selling price = cost price + profit
Calculation∶
Let the cost price is Rs. x
Selling price $=\mathit{x}\mathit{–}6\%$ of x
⇒ 94x/100
New selling price $=\mathit{x}+15\%$ of x
$\Rightarrow \left(94\mathit{x}/100\right)+15750=\mathit{x}+15\%$ of x
$\Rightarrow \left(94\mathit{x}/100\right)\mathit{–}\left(115\mathit{x}/100\right)=-15750$
$\Rightarrow 21\mathit{x}/100=15750$
$\Rightarrow \mathit{x}=\mathit{R}\mathit{s}.75,000$
∴ The cost price is Rs. 75,000.
