$20\mathrm{gm}$ of water at $30^{\circ }\mathrm{C}$ is mixed with $5\mathrm{gm}$ of ice at $-10^{\circ }\mathrm{C}$. Find the final temperature of mixture (in ${}^{\circ }\mathrm{C}$) if latent heat of fusion of ice is $80cal/gm$, specific heat of water = $1cal/gm$${}^{\circ }\mathrm{C}$, specific heat of ice = $0.5cal/gm$${}^{\circ }\mathrm{C}$.
