Condition of concurrency -

Solve the equations of two lines to get a point and satisfy it in the third equation of line.

-

4ax+2ay+c=0 and 5bx+2by+d=0

Let the point of intersection be (K, -K)

From both equations, we get

2aK+c = 0;3bK+d=0

$=> K\:=\:\frac{-c}{2a}\:=\:\frac{-d}{3b}\\\\=> 3bc-2ad\:=0$

Option 1)

This option is correct.

Option 2)

This option is incorrect.

Option 3)

This option is incorrect.

Option 4)

This option is incorrect.
