Question

The average age of three people running for election is 42. A fourth person joins the race and the average drops to 40. What is the fourth

person's age?
A. 32
B. 34
c. 35
D36
E. 40

Answer 1

B - 34 years old

Explanation:

First you have to multiply 42 times 3 to find the total age of the three people. Then multiply 40 times 4 to find the age of the four people in all. Subtract.

42 × 3 = 126

40 × 4 = 160

160 - 126 = 34
