If the lines `x+2ay+a=0, x+3by+b=0` and `x+4cy+c=0` are concurrent then `a,b,c` are in

If the lines : x+2ay+a=0, x+3by+b=0 and x+4cy+c=0 are concurrent, where a,b,c are non-zero real numbers, then :

If the lines x+2ay+a=0, x+3by+b=0, x+4cy+c=0 are concurrent, then a, b, c are in

If the lines x+2ay+a=0, x+3by+b=0, x+4cy+c=0 are concurrent, then a,b and c are in

For a ne b ne c if the lines x + 2ay + a = 0 , x + 3by + b = 0 and x + 4cy + c = 0 ar concurrent , then a , b, c are in

If the lines x+ 3y -9=0 , 4x+ by -2 =0, and 2x -4 =0 are concurrent, then the equation of the lines passing through the point (b,0) and concurrent with the given lines, is

If the lines 2x-ay+1=0, 3x-by+1=0, 4x-cy+1=0 are concurrent, then a, b, c are in

If the three distinct lines x + 2ay + a = 0 , x+ 3by + b = 0 and x + 4ay + a = 0 are concurrent , then the point (a,b) lies on a .

If the three distinct lines x + 2ay + a = 0 , x+ 3by + b = 0 and x + 4ay + a = 0 are concurrent , then the point (a,b) lies on a .
