Answer 1

cp=100/100+profit perceng ×sp
cp=100/100+20=120×18000
cp=100/120×18000
cp=15000rs

Answer 2

 Let the cost price of the scooter be Rs 100. Then, Profit = Rs 20

            S.P. = C.P. + Profit = Rs 100 + Rs 20= Rs 120
            Thus, if the S.P. is Rs 120, then C.P. = Rs 120 – 20 = Rs 100

            If the S.P. is Rs 18000, then C.P. = Rs (100120 x 18000) = Rs 15000

            Hence, the cost of the scooter = Rs 15000
