The sum of the ages of 3 people A, B and C is 90 years. What would be the total of their ages 4 years back?
-
A.
74 years
-
B.
78 years
-
C.
86 years
-
D.
80 years
Correct Answer:
B. 78 years
Explanation:
To find the total age of three individuals four years ago, you must subtract four years from each person's current age. Since there are three people (A, B, and C), the total reduction is 12 years (3 people multiplied by 4 years). Subtracting 12 from the current combined total of 90 years results in a sum of 78 years.
