Solution

We have,
$S . P = R s . 572$
$G a i n % = 30 %$
$C . P = ?$

We know that
$G a i n % = \frac{S . P - C . P}{C . P} \times 100$

$30 = \frac{572 - C . P}{C . P} \times 100$

$30 C . P = (572 - C . P) \times 100$

$30 C . P = 57200 - 100 C . P$

$130 C . P = 57200$

$C . P = \frac{57200}{130} = R s . 440$

Hence, this is the answer.
