JEE Main 2023 — Ellipse Question with Solution

Let the ellipse $$E:x^2+9y^2=9$$ intersect the positive x and y-axes at the points A and B respectively. Let the major axis of E be a diameter of the circle C. Let the line passing through A and B meet the circle C at the point P. If the area of the triangle with vertices A, P and the origin O is $$\frac{m}{n}$$, where m and n are coprime, then $$m-n$$ is equal to :
