both the quantities of water have same mass (50 grams) so the temperature will be the mean of the two initial temperatures,
so it is 30 degree celsius
so it is 30 degree celsius

Answer:
30°C
Explanation :
Given,
Mass m1 = 50g
Temperature T1 = 40°C
Mass m2 = 50g
Temperature T2 = 20°C
By using method of mixtures,
Final temperature
T = m1T1 + m2T2/m1 +m2
= 50×40+50×20/50+50
= 2000+1000/100
= 30°C
The final temperature = 30°C
