Madhya Pradesh Police Exam Model Paper 10

GIVEN:
By selling a TV at Rs. 25000, a dealer suffers a loss of 12%.
CONCEPT:
Basic concept of Profit and Loss.
FORMULA USED:
SP = CP × [1 – loss]/100
SP = CP × [1 + profit]/100
CALCULATION:
Let the cost price of the TV be x.
Now, by selling at Rs. 25000, a loss of 12% is incurred.
Hence,
$\left(1\mathit{–}12/100\right)\mathit{x}=25000$
$\Rightarrow \mathit{x}=25000/0.88$
Now, to make a profit of 10%, he should sell it at $\left(1+10/100\right)\mathit{x}$
$=110/100\times \left(25000/0.88\right)$
$=\mathit{R}\mathit{s}.31250$
