Two resistances X Omega and Y Omega are ...

Two resistances `X Omega` and `Y Omega` are connected in the left and right gap of a metre bridge. A null point was found on the bridge wire such that the ratio of lengths of two segments of wire is `2:3`. The distance of the null point was measured from the left end of the wire. When the valueof X is increased by `20 Omega`, the position of the null point divides the wire into segments of lengths in the ratio `4:1`.Determine X and Y.
