Generally I.S.I entrance hits the floor in the month of May. ISI 2018 Problem 2 discussion has been written for I.S.I preparation series.. The book, Challenge and Thrill of Pre-College Mathematics is very useful for preparation of I.S.I.


The Problem


Suppose that \(PQ\) and \(RS\) are two chords of a circle intersecting at a point \(O\). It is given that \(PO=3 \text{cm}\) and \(SO=4 \text{cm}\). Moreover, the area of the triangle \(POR\) is \(7 \text{cm}^2\). Find the area of the triangle \(QOS\).
