3-D Geometry for JEE Advance

Geometry Level pending

A line \(L_1\) with direction ratios \((-3,2,4)\) passes through the point A\((7,6,2)\) and a line \(L_2\) with direction ratios \((2,1,3)\) passes through the point B\((5,3,4)\). A line \(L_3\) with direction ratios \((2,-2,-1)\) intersects \(L_1\) and \(L_2\) at C and D. Then C and D are:

  1. \((1,10,10)\)
  2. \((-1,12,11)\)
  3. \((7,4,7)\)
  4. \((3,8,9)\)

Details: There can be multiple correct answers. If your answer is choice 1 and 2 then type your answer as 12 (choices must be in ascending order).
