Solution

The correct option is A Rs 900
Here, $S . P ._{1} - S . P ._{2} = - 1494, x = - 10, y = \frac{25}{2}$ \)
Using the formula,
$\frac{C . P}{100} = \frac{S . P_{1} - S . P_{2}}{x - y}$
we get, $\frac{C . P}{100} = (\frac{- 72}{5 - 13})$
$\Rightarrow C . P . = \frac{72}{8} \times 100 = R s 900$
