Expert Answer:

Let T be be the final equilibrium temperature after mixing liquid-A and liquid-C
 
Heat energy gained by liquid-A = mA Cp ( T - 10 )
 
Heat energy lost by liquid-C = mC Cp ( 40 - T )
 
By conservation of energy Heat gain equals heat loss.
 
If we assume masses of liquids are equal and Specif heats are equal ( A and C are same liquid) , then by conservation of energy
 
 
mA Cp ( T - 10 ) = mC Cp ( 40 - T )
 
(T-10) = ( 40 - T )
 
from above expression we get , T = 25o C
