    A)  16000                         

    B)  14000

    C)  18000             

    D)       12000

    Correct Answer: D

    Solution :

      Let C.P=Rs. \[100\] As there is profit % as 15 so S.P = \[=100+15=\]Rs. 115 Let the C.P of the car be Rs \[x\] Now make proportions as \[100/x=115/13800\] By Cross multiplication, we get \[115x=100\times 13800\] \[115x=1380000\] So, \[x=1380000/115\] \[x=\] Rs 12000 Hence, the cost price of the car is Rs 12000.
