A person sells a colour $T V$ at $10 \%$ below the cost price. Had he received $Rs.\,1494$ more, he would have made a profit of $12 \frac{1}{2} \% .$ What was the cost price of the colour $TV?$ (in $Rs.$)

A

$6400$

B

$7200$

C

$6640$

D

None of these

Solution

Here, $S.P _{-1}- S.P _{-2}=-72, x=5, y=13$

Using the formula,

$\frac{ C.P. }{100}=\frac{ S.P _{1}- S.P _{2}}{x-y}$

we get, $\frac{ C.P. }{100}=\frac{-1494}{-10-25 / 2}=\frac{1494}{45 / 2}$

$\Rightarrow \quad CP =\frac{1494 \times 2 \times 100}{45}=Rs. 6640$
