    In the given figure, AD, BF and CE are medians of a triangle ABC and O is a point of concurrency of medians. If AD = 6 cm., then OD is equal to

    A)  2 cm                           

    B) 3 cm                    

    C) 4 cm                     

    D) \[\frac{2}{3}\,cm\]

    Correct Answer: A

    Solution :

     Since, O is the centroid of \[\Delta \,ABC,\] \[\therefore \]  \[OD=\frac{1}{3}AD\]                 \[=\frac{1}{3}\times 6=2cm\]
