Under the same load, wire $\displaystyle A$ having length $\displaystyle 5.0$ m and cross section $\displaystyle 2.5 \times 10^{-5} \mathrm{~m}^2$ stretches uniformly by the same amount as another wire B of length $\displaystyle 6.0$ m and a cross section of $\displaystyle 3.0 \times 10^{-5}$ $\displaystyle \mathrm{m}^2$ stretches. The ratio of the Young's modulus of wire A to that of wire B will be :
