357288 With resistance \(P\) and \(Q\) in the left and the right gap respectively of a metre bridge, the null point divides the wire in the ratio \(3: 4\). When \(P\) and \(Q\) are increased by \(20\,\Omega \) each, the null point divides the wire in the ratio \(5: 6\). The values of \(P\) and \(Q\) are
