    A) 21m               

    B)          27m

    C) 29 m               

    D)          35m

    Correct Answer: C

    Solution :

        Ratio of the distances covered by A and B = 190 : 200 =1710 : 1800 \[\Rightarrow \] Ratio of the distances covered by B and C =180 : 200 = 1800 : 2000 \[\Rightarrow \] Ratio of the distances covered by A and C = 1710 : 2000 = 171 : 200 Hence, C will give a start of (200 m - 171 m) = 29 m to A in the same race.
