Answer:

The fourth person is 34 years old.

Step-by-step explanation:

Step 1: Find ages of the 3 people running for election

42*3=126  Their ages combined is 126.

Step 2: Find the ages of the 4 people running for election.

40*4=160

Step 3: Subtract the two ages.

160-126=34.  

The 4th person is 34.
