${\mathrm{AB}}_2$ is $10\%$ dissociated in water to ${\mathrm{A}}^{2+}$ and ${\mathrm{B}}^{-}$. The boiling point of $10.0$ molal aqueous solution of ${\mathrm{AB}}_2$ is-- ${}^{\circ }\mathrm{C}$. (Round off to the Nearest Integer).

[Given : Molal elevation constant of water ${\mathrm{K}}_{\mathrm{b}}=0.5 \mathrm{K} \mathrm{kg}{ \mathrm{mol}}^{-1}$ boiling point of pure water$=100°\mathrm{C}$]
