When $\displaystyle 10$ mL of an aqueous solution of $\displaystyle \mathrm{KMnO}_4$ was titrated in acidic medium, equal volume of $\displaystyle 0.1$ M of an aqueous solution of ferrous sulphate was required for complete discharge of colour. The strength of $\displaystyle \mathrm{KMnO}_4$ in grams per litre is \_\_\_\_ $\displaystyle \times 10^{-2}$. (Nearest integer) [Atomic mass of $\displaystyle \mathrm{K}=39, \mathrm{Mn}=55, \mathrm{O}=16$ ]
