How can steam be at 20oC. I think there is some mistake in the question. However, you can solve it the following way.
Find heat required to convert steam into water ie be Q1=m1L
Then find heat required to bring the water at temperature T, be Q2=m1S∂T
Now, calculate the heat required to take water at temperature T, Q3=m1S∂T.
Now, by principle of calorimetry, Q+ Q= Q3
