JEE Math Practice Question
A line with direction cosines proportional to $$2,1,2$$ meets each of the lines $$x=y+a=z$$ and $$x+a=2y=2z$$ . The co-ordinates of each of the points of intersection are given by :
- A.$$\left( {2a,3a,3a} \right),\left( {2a,a,a} \right)$$
- B.$$\left( {3a,2a,3a} \right),\left( {a,a,a} \right)$$
- C.$$\left( {3a,2a,3a} \right),\left( {a,a,2a} \right)$$
- D.$$\left( {3a,3a,3a} \right),\left( {a,a,a} \right)$$
