In an experiment, the percentage of error occurred in the measurement of physical quantities $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and $\mathrm{D}$ are $1\%, 2\%, 3\%$ and $4\%$ respectively. Then the maximum percentage of error in the measurement $\mathrm{X}$, where $\mathrm{X}=\frac{{\mathrm{A}}^2{\mathrm{B}}^{{\displaystyle \raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}}}{{\mathrm{C}}^{{\displaystyle \raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$3$}\right.}}{\mathrm{D}}^3}$, will be:
