Equal increase in length occurred in two wires, one is of steel of cross sectional area `3.0 xx10^-5 m^2` and another one is of copper of cross sectional area `4.0xx10^-5m^2`, by applying equal load on them. If Young's modulus of steel and copper are `2.0xx10^11 Nm^-2` and `1.0xx10^11Nm^-2` respectively, then the ratio of their initial lengths will be
