Q 1317223180.     The equation of the plane that meets the coordinate axes at the points `A,B,C` respectively and the centroid of the `Delta ABC` is `(2,1,5)` is ?

A

`5x+10y+2z-30=0`

B

`2x+y+5z-30=0`

C

`5x+10y+2z+30=0`

D

`5x+10y+2z+30=0`

HINT

Let the points on the coordinate axes, at which the plane meets be `A(a,0,0), B(0,b,0)` and `C(0,0,c)` `therefore` The equation of the plane is `frac{x}{a}+frac{y}{b}+frac{z}{c}=1`
