`A(4,\ 2),\ B(6,5)` and `C(1,\ 4)` are the vertices of ` A B C` . Find the coordinates of the points `Q` on median `B E` such that `B Q : Q E=2:1`

A

Q=`(11/3,11/3)`

B

Q=`(10/3,11/3)`

C

Q=`(11/3,10/3)`

D

Q=`(10/3,10/3)`

Text Solution

Verified by Experts

The correct Answer is:
A

let's take a pont D in mid of B and C, E between A and C, F between A and B
co-odenates of D will be
`x_d`=`(6+1)/2`=`7/2`
`y_d`=`(5+4)/2`=`9/2`
so, D=`(7/2, 9/2)`
similarly, E and F will be
E=`(5/2,3)` and F= `(5,7/2)`
Q is on median BE at the ration of 2:1
