A 50 ml mixture of $\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3$ and $\mathrm{NaHC}{\mathrm{O}}_3$ is titrated against 1 M $\mathrm{HCl}$. If ${\mathrm{V}}_1$ L and ${\mathrm{V}}_2$ L are consumed when phenolphthalein and methyl orange are used as indicators, respectively, in two separate titrations, which of the following is true for molarities in the original solution?
