1)

The line which passes through the origin and intersect the two lines

x12=y+34=z53, x42=y+33=z144 is

 


A) x1=y3=z5

B) x1=y3=z5

C) x1=y3=z5

D) x1=y4=z5

Answer:

Option A

Explanation:

Let the line be xa=yb=zc ...(1)

If line (1) intersects with the line x12=y+34=z53, then

|abc2434314|=0

9a - 7b - 10c = 0   ...(2)

from (1) and (2) , we have,

a1=b3=c5

.'. The line  is x1=y3=z5
