Question

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