Question
The average age of a family of five is 32 years.
If the ages of four family members are 28, 34, 30, and 38, how old is the fifth family member?
Solution
To find the age of the fifth family member, we first need to find the total age of the family. Since the average age is 32 years and there are 5 family members, the total age of the family is 32 years * 5 = 160 years.
Next, we add up the ages of the four known family members: 28 + 34 + 30 + 38 = 130 years.
Finally, we subtract the total age of the four known family members from the total age of the family to find the age of the fifth member: 160 years - 130 years = 30 years.
So, the fifth family member is 30 years old.
