Answer 1

To find out how many people above age 30 are for the candidate, we need to look at the age groups 31-40 and Over 40 and sum the number of people who are "For" the candidate in those groups.

From the table:

• For the age group 31-40, the number of people who are "For" the candidate is 30.
• For the age group Over 40, the number of people who are "For" the candidate is 25.

Now, we add these two amounts together:

30 (For in 31-40 age group) + 25 (For in Over 40 age group) = 55

Therefore, the number of people above age 30 who are for the candidate is 55.

The correct answer is 55.
