Question

can you please answer the question​

Answer 1

CP of 16 notebook = Sp of 30 notebooks

To find Gain

SP = Rs 30

CP = RS 16

we use formula

Gain = SP - CP

Gain = 30 - 16

Gain = 14

then we find gain%

we use formula

gain% = Gain / Cost price * 100

gain%= 14 / 16 * 100

gain % = 87.5%
