Three containers \[{{C}_{1}}\], \[{{C}_{2}}\] and \[{{C}_{3}}\] have water at different temperatures. The table below shows the final temperature T when different amounts of water (given in liters) are taken from each container and mixed (assume no loss of heat during the process)

\[{{C}_{1}}\]	\[{{C}_{2}}\]	\[{{C}_{3}}\]	T
\[1\ell \]	\[2\ell \]	-	\[60{}^\circ C\]
-	\[1\ell \]	\[2\ell \]	\[30{}^\circ C\]
\[2\ell \]	-	\[1\ell \]	\[60{}^\circ C\]
\[1\ell \]	\[1\ell \]	\[1\ell \]	\[\theta \]

The value of \[\theta \] (in \[{}^\circ C\] to the nearest integer) is _______.               [JEE MAIN Held on 08-01-2020 Evening]
