In a joint family of 16 persons, the eldest and the youngest members have an age difference of 82 years. If these two are left
out of the counting, then the average age of the remaining 14 persons is 28. The average age of the entire family being 30, what
is the age of the eldest person?
85 years
88 years
76 years
60 years
- The total number of family members is 16, and the total average age is 30.
- This means the total age for all members is \(16 \times 30 = 480\).
- The ages of the two members excluded are the eldest and the youngest, with an age difference of 82 years.
- With the remaining 14 members, the average age is 28, so their total age is \(14 \times 28 = 392\).
- Therefore, the combined age of the eldest and youngest is \(480 - 392 = 88\).
- Let the youngest be \(x\), so the eldest is \(x + 82\).
- Equation: \(x + (x + 82) = 88\).
- Solving: \(2x + 82 = 88 \rightarrow 2x = 6 \rightarrow x = 3\).
- So the youngest is 3 years old and the eldest is \(3 + 82 = 85\) years old.
- The correct answer is Option 1: 85 years.
