A. 15 5/15%

B. 18 2/11 %

C. 6 2/3%

D. 30%

Answer : B. 18 2/11 %


Explanation:

    Given :
    Cost Price = 13 and Selling Price = 11

    According to the formula,
    Profit % = ( (C.P - S.P / S.P) * 100 ) %

    Profit % = ( (13 - 11 / 11) * 100 ) %
    = ( (2 / 11) * 100 ) %
    = 18 2/11 %
