The second T-ds relation reduces to Tds = dh at constant pressure (cp), use the superheated table

Question:

The second T-ds relation reduces to Tds = dh at constant pressure (cp), use the superheated table of water (Table B-3) to evaluate the two sides of this equation at
(a) 100 kPa, 200oC.
(b) 50 MPa, 500oC. Calculate for dT = 10oC.
(c) What-if Scenario: What would the answer in part (b) be if the PC system state daemon were used with dT = 10oC?
