Question

CP=500, gain % = 30 , SP is​

Answer 1

$S.P= ( 1 + \frac{gain\%}{100} ) \times C.P \\ \: \\ \implies \: S.P = (1 + \frac{30}{100} ) \times 500 \\ \\ \implies \: S.P = ( \frac{100 + 30}{100} ) \times 500 \\ \\ \implies \: S.P = ( \frac{130}{100} ) \times 500 \\ \\ \implies \: S.P = \frac{130}{1 \cancel0 \cancel0} \times 5 \cancel0 \cancel0 \\ \\ \implies \: S.P \: = 130 \times 5 \\ \\ \implies {\red{650.... \: \: \: \: (ans)}}$
