A circle touches the line 4x+3y=12 at D and positive x,y axes. Let DE be
diameter of circle and OE intersect the line at F, then [4DF] is equal to ([.] is GIF) (Provided OE<OD and O being origin ).
Equation of circle is x2+y2−2x−2y+1=0D is 95,85
taking (1,1) as and point E is 15,25
OE has equation y=2x
⇒F is 65,125⇒DF=1
