Dear Abdul,


 Use componendo and divinend rule :



first take, s-a/s-b = 1 /2

or  (2s - a -b) / b-a  =   1+2/ 1-2

or a+b+2c/b-a = -3 eq. 1

similarly, make 2 more equation n solve them for a,b and c.

The circle drawn with variable chord x+ay=5 (a being parameter) of the parabola y^2=20x as diameter will touch the line:A) x=-5B) y=-5C) x+y =-5D) x-y+5=0
The chord is the focal chord, because focus (0,5) is satisfied on it. So it always passes through the directrix. Hence x=-5 is the right answer
