Answer the questions independently of each other.The average age of members in my family excluding me is 27 years but including me is 22.25 years. If my family includes only myself, my parents and my siblings and there are two different pairs of members whose ages differ by 3 years and 4 years, then which of the following can be the age of any one member of my family? (All the ages are natural numbers)25 years36 years35 years34 years

To solve this problem, we first need to find out the total age of all family members excluding the person in question.

Given that the average age of the family excluding the person is 27 years, and the family consists of the person, their parents, and their siblings, we can infer that there are at least 4 people in the family (the person, their two parents, and at least one sibling).

Therefore, the total age of the family members excluding the person is 27 years * 4 = 108 years.

Next, we find out the total age of all family members including the person.

Given that the average age of the family including the person is 22.25 years, and we know there are at least 5 people in the family (the person, their two parents, and at least two siblings), the total age of all family members is 22.25 years * 5 = 111.25 years.

However, since all ages are natural numbers, the total age of all family members must also be a natural number. This means that there must be more than 5 people in the family.

If we assume there are 6 people in the family, the total age of all family members would be 22.25 years * 6 = 133.5 years, which is still not a natural number.

If we assume there are 7 people in the family, the total age of all family members would be 22.25 years * 7 = 155.75 years, which is still not a natural number.

If we assume there are 8 people in the family, the total age of all family members would be 22.25 years * 8 = 178 years, which is a natural number.

Therefore, there must be 8 people in the family, and the person's age is 178 years - 108 years = 70 years.

Given that there are two different pairs of members whose ages differ by 3 years and 4 years, the possible ages of the family members could be 70 years (the person), 27 years, 24 years, 27 years, 23 years, 27 years, and 27 years.

Therefore, the possible ages of any one member of the family are 70 years, 27 years, 24 years, and 23 years.

So, none of the ages provided (25 years, 36 years, 35 years, 34 years) can be the age of any one member of the family.
