Equal masses of three liquids A, B and C have temperatures $10{}^{\circ }\mathrm{C}$, $25{}^{\circ }\mathrm{C}$ and $40{}^{\circ }\mathrm{C}$ respectively. If A and B are mixed, the mixture has a temperature of $15{}^{\circ }\mathrm{C}$. If B and C are mixed, the mixture has a temperature of $30{}^{\circ }\mathrm{C}$. If A and C are mixed the mixture will have a temperature of
