The temperature of equal masses of three different liquids $x$, $y$ and $z$ are $10^\circ\text{C}$, $20^\circ\text{C}$ and $30^\circ\text{C}$ respectively. The temperature of mixture when $x$ is mixed with $y$ is $16^\circ\text{C}$ and that when $y$ is mixed with $z$ is $26^\circ\text{C}$. The temperature of mixture when $x$ and $z$ are mixed will be:
(1) $25.62^\circ\text{C}$
(2) $20.28^\circ\text{C}$
(3) $28.32^\circ\text{C}$
(4) $23.84^\circ\text{C}$
