Question

Column I		Column II
A	If $3a-2b+5c=0$, then family of straight lines $ax+by+c=0$ are always concurrent at a point whose co-ordinates is $(a,b)$, then the values of $a-5b$	p	$3\sqrt{2}$
B	Number of integral values of $b$ for which the origin and the point $(1,1)$ lie on the same side of the straight line $a^{2}x+aby+1=0$ for all $a\in R-\{0\}$ is	q	5
C	Vetices of a right angled triangle lie on a circle and extrimites of whose hypotenuse are $(6,0)$ and $(0,6)$, then radius of circle is	r	12
D	If the slope of one of the lines represented by $a{x}^2-6xy+y^2=0$ is square of the other, then a is	s	3
		t	8
