Similar to the % labelling of oleum, a mixture of ${\mathrm{H}}_3{\mathrm{PO}}_4$ and ${\mathrm{P}}_4{\mathrm{O}}_{10}$ is labelled as $(100+\mathrm{x})\%$ where $x$ is the maximum mass of water which can react with ${\mathrm{P}}_4{\mathrm{O}}_{10}$ present in 100 gm mixture of ${\mathrm{H}}_3{\mathrm{PO}}_4$ and ${\mathrm{P}}_4{\mathrm{O}}_{10}$. If such a mixture is labelled as $127\%$. Mass of ${\mathrm{P}}_4{\mathrm{O}}_{10}$ in 100 gm of mixture, is
