Let O be the origin, A(1, 0) and B(0, 1) and P(x, y) are points
such that xy > 0 and x + y < 1, then
ekuk O ewy fcUnq gS A(1, 0)
> 0
Show answer and solution
xy > 0 P either lies in first quadrant or in
third quadrant
x + y < 1 P lies below line x + y = 1 P js[kk x + y = 1
third quadrant
x + y < 1 P lies below line x + y = 1 P js[kk x + y = 1
