Equal masses of three liquids 
and C have temperatures 
and 
, respectively. If A and B are mixed, the mixture has a temperature of 
. If B and C are mixed, the mixture has a temperature of 
. If A and C are mixed, the mixture will have a temperature of
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
When A and B are mixed,
… (i)
When B and C are mixed,
… (ii)
From Eqs. (i) and (ii), we get
Now, let 
be the equilibrium temperature when A and V are mixed.
Then, 
or 
= 40 – 
or
