# 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. $$(3,8,9)$$
