$Let \: \: \: original \: \: CP = Rs. \: 100.$

$Then, \: \: the \: \: Marked \: \: Price = 40 \: percent \: \: of \: \: \: \: \: \: \: \: 100 + 100 = 140 \:$

$SP \: \: = 140 - 25 \: percent \: \: of \: \: \\ 140 = 105.$

$Profit \: \: \: \: \: percent \: \: = (5 \times 100)/100 = 5 \: percent$

$Net \: \: \: \: Graphic \: \: \: \: Change \: \: \: \: Method:$

$100 == 40 \: percent \: \: \: UP ==> 140 == 25 \: percent \: \: \: \: \: discount ==> 105.So, Profit \: percent \: = 5 \: percent \: .$
