$Hi \: \: !!! \\ \\ Here \: \: is \: \: your \: \: answer, \\ \\ C.P \: \: of \: 12 \: \: pens = Rs. 120 \\ C.P \: \: of \: \: 1 \: \: pen \: = \frac{120}{12} = Rs.10 \\ \\ S.P \: \: of \: \: 1 \: pen \: = Rs.15 \\ S.P \: \: of \: \: 12 \: \: pens \: =Rs.180 \\ \\ So, \\ C.P < S.P = profit \\ \\ Profit = S.P - C.P \\ Profit = 180 - 120 = Rs.60 \\ \\ Profit\% = \frac{Profit}{C.P} \times 100 \\ \\ Profit\% = \frac{60}{120} \times 100 = 50\% \\ \\ \\ Hope \: \: it \: \: helps.$
