Answer 2

$let \: cp \: be \: x\\ sp = rs.530 \\ p\% = 6\% \\ p\% = \frac{p}{cp} \times 100 \\ 6 = \frac{p}{x} \times 100 \\ 6x = 100p \\ x = \frac{100p}{6} \\ \\ x = \frac{50p}{3} \\ atq \\ cp + p = 530 \\ \frac{50p}{3} + p = 530 \\ \frac{53p}{3} = 530 \\ p = \frac{530 \times 3}{53} \\ p = rs.30 \\ cp = 530 - 30 \\ cp = rs500$
