n-factor of$\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}\Rightarrow 5$
n-factor of${\mathrm{C}}_2{\mathrm{O}}_4^{2-}\Rightarrow 2$
Ratio of n-factors of$\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}$and${\mathrm{C}}_2{\mathrm{O}}_4^{2-}$is 5 : 2
So, molar ratio in balanced reaction is 2 : 5
Hence the balanced equation is
$2\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}+5{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+16{\mathrm{H}}^{+}\to 2\mathrm{M}{\mathrm{n}}^{2+}10\mathrm{C}{\mathrm{O}}_2+8{\mathrm{H}}_2\mathrm{O}$
