The temperature of equal masses of three different liquids $\displaystyle x, y$ and $\displaystyle z$ are $\displaystyle 10^{\circ} \mathrm{C}, 20^{\circ} \mathrm{C}$ and $\displaystyle 30^{\circ} \mathrm{C}$ respectively. The temperature of mixture when $\displaystyle x$ is mixed with $\displaystyle y$ is $\displaystyle 16^{\circ} \mathrm{C}$ and that when $\displaystyle y$ is mixed with $\displaystyle z$ is $\displaystyle 26$°C. The temperature of mixture when $\displaystyle x$ and $\displaystyle z$ are mixed will be :
