A $\displaystyle 1$ kg block subjected to two simultaneous forces $\displaystyle (2 \hat{\mathrm{i}}+3 \hat{\mathrm{j}}+4 \hat{\mathrm{k}}) \mathrm{N}$ and $\displaystyle (3 \hat{\mathrm{i}}-\hat{\mathrm{j}}-2 \hat{\mathrm{k}}) \mathrm{N}$ is moved a distance of $\displaystyle 25$ m along $\displaystyle (3 \hat{\mathrm{i}}-4 \hat{\mathrm{j}})$ direction. The work done in this process is $\displaystyle \_\_\_\_$J.
