Initially

$0.1\times 100\times 10^{-3}$ mole

$2{\mathrm{KMnO}}_4+3{\mathrm{H}}_2{\mathrm{SO}}_4+5{\mathrm{H}}_2{\mathrm{O}}_2\to {\mathrm{K}}_2{\mathrm{SO}}_4+2{\mathrm{MnSO}}_4+3{\mathrm{H}}_2\mathrm{O}+{\mathrm{SO}}_2$

no. of moles of ${\mathrm{H}}_2{\mathrm{O}}_2$ reacted with ${\mathrm{KMnO}}_4=\frac{5}{2}\times 0.01=0.025$

Molarity of H 2 O 2 solution $=\frac{0.025}{280}\times 1000$

Volume strength $=11.2\times$ molarity $=11.2\times \frac{0.025}{280}\times 1000=1$
