RMO is really insane
Let \(ABC\) be a triangle.Let \(D\) and \(C\) be points on segments \(BC\) such that \(BD=DE=EC\).
Let \(F\) be the midpoint of \( AC\). Let BF intersect \(AD\) in \(P\) and \(AE \) in \( Q\) respectively. Determine the ratio of area of the triangle \(APQ\) to that of the quadrilateral \(PDEQ\).
