Problem

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) [8 Jan. 2020 III]

$C_1$	$C_2$	$C_3$	$T$
1 l	2 l	—	$60^\circ\text{C}$
—	1 l	2 l	$30^\circ\text{C}$
2 l	—	1 l	$60^\circ\text{C}$
1 l	1 l	1 l	$\theta$

The value of

\theta

(in

^\circ\text{C}

to the nearest integer) is ________.
