The reaction is given by 2 \mathrm{KMnO}_4+3 \mathrm{Mn}^{2+}+4 \mathrm{OH}^{-} \rightarrow 5 \mathrm{MnO}_2+2 \mathrm{H}_2 \mathrm{O} 

So, 2 moles of \mathrm{KMnO}_4 reacts with 3 moles of \mathrm{MnCl}_2 to give 5 moles of \mathrm{MnO}_2

And 2/5 moles of \mathrm{KMnO}_4  reacts with 3/5 moles of \mathrm{MnCl}_2 to give 1 mole of \mathrm{MnO}_2.
