The labelled price of a cupboard is $Rs$ $6500 .$ The shopkeeper sold it by giving $5 \%$ discount on the labelled price and earned a profit of $15 \% .$ What approximately is the cost price of the cupboard? (in $Rs.$)
A
$5000$
B
$5350$
C
$5600$
D
$5800$
Solution
Labelled price of cupboard $=Rs. 6500$
Selling price $(S.P.)$ $=\frac{95}{100} \times 6500=Rs. 6175$
Profit $\%=15$
Let $x$ be the cost price
$\therefore \quad \frac{ S.P. – C.P. }{ C.P. } \times 100=\% \text { profit }$
i.e. $\quad \frac{6175-x}{x} \times 100=15$
i.e. $\frac{6175-x}{x}=\frac{15}{100}$
i.e. $\frac{6175}{x}=1+\frac{15}{100}=\frac{115}{100}$
$\therefore$ $x=\frac{6175 \times 100}{115}=5369.56=Rs. 5350$
