Which of the following pairs of physical quantities does not have same dimensional formula?

Measure of two quantities along with the precision of respective measuring instrument is$A=2.5 \mathrm{m} {\mathrm{s}}^{-1}\pm 0.5 \mathrm{m} {\mathrm{s}}^{-1}$ and $\mathrm{B}=0.10 \mathrm{s}\pm 0.01 \mathrm{s}$.

Find the value of $\mathrm{AB}$ will be
