    In the given figure, ABC is a triangle in which D and E are the middle points of BC and AC respectively. If AO = 6 cm, find the length of OD.

    A)  3 cm                             

    B)  6 cm                    

    C)       4 cm                     

    D)  2cm                  

    Correct Answer: A

    Solution :

      Medians of any triangle intersects each other in the ratio \[2:1\]. \[\therefore \]  \[OD:AO\,\,\,:\,\,\,:\,\,\,1:2\] \[\therefore \]  \[OD=\frac{1}{2}\times 6\,cm=3\,cm\] \[\therefore \]
