1.	A ray M is sent along the line x−02=y−22=z−10 and is reflected by the plane x=0 at point A. The reflected ray is again reflected by the plane x+2y=0 at point B. The initial ray and final reflected ray meets at point J. Then absolute value of sum of the co-ordinates of point J is
Answer» A ray $M$ is sent along the line $\frac{x - 0}{2} = \frac{y - 2}{2} = \frac{z - 1}{0}$ and is reflected by the plane $x = 0$ at point $A$ . The reflected ray is again reflected by the plane $x + 2 y = 0$ at point $B$ . The initial ray and final reflected ray meets at point $J$ . Then absolute value of sum of the co-ordinates of point $J$ is
