Answer 2

As profit percent is given, we use the following formula.
        CP (100 + P%)
SP = ------------------
           100
        12 (100 + 6)
SP = ------------------
           100
        12 x 106
SP = -------------
           100
           1272
SP = -----------
           100
∴ Selling price =  Rs.12.72
