The temperature of equal masses of three different liquids

x

y

and

z

are

10^\circ C,\,\,20^\circ C

and

30^\circ C

, respectively. The temperature of mixture when

x

is mixed with

y

16^\circ C

and that when

y

is mixed with

z

26^\circ C

. The temperature of mixture when

x

and

z

are mixed will be

View answer and explanation

Correct option: C

23.84^\circ C

Option C (

23.84^\circ C

) is correct because it is derived from setting up and solving equations based on the heat exchange between the liquids when mixed.
