The number of people above age 30 who are for the candidate can be found by adding up the number of people in the "For" category for the age groups 31-40 and over 40.
For the age group 31-40, there are 30 people in the "For" category.
For the age group over 40, there are 25 people in the "For" category.
Adding these two numbers together, we get:
30 + 25 = 55
Therefore, there are 55 people above age 30 who are for the candidate.
