Question
If the orthocenter and circumcentre of a triangle are (0,0) and (3,6) respectively then the centroid of the triangle is
Options:
A .  (1,2)
B .  (2,4)
C .  (23,43) 
D .  (13,23) 
Answer: Option B
:
B
In any triangle centroid divides the line joining orthocenter and circumcentre internally in the ratio 2 : 1.
Applying section formula to find the point which divides the line joining (0,0) in the ratio 2:1 , we get the coordinated of centroid equal to (2,4).
