Line (1+lambda)x+(4-lambda)y+(2+lambda)=...

Line `(1+lambda)x+(4-lambda)y+(2+lambda)=0 and (4-lambda)x-(1+lambda)y+(6-3lambda) =0` are concurrent at points A and B respectively and intersect at C then locus of centroid of `DeltaABC " is " lambda` is parameter

A

`(x+3/2)^2+(y+7/10)^2=17/50`

B

`(x-3/2)^2+(y-7/10)^2=17/50`

C

`(x-3/2)^2+(y+7/10)^2=17/450`

D
