Let A, B, C be three points on a plane and O be the origin point on this plane. Put

and

P is a point inside the triangle ABC. Suppose that the rato of the areas of is 2:3 :5 respectively

(1) The straight line BP intersects the side AC at point Q

Find AQ:QC

How do I even start with this? Can i assume the triangle to be a right triangle so that things might be easier?
