[Ans] To boast that their age is a prime number, a nonagenarian must be how old?

To boast that their age is a prime number, a nonagenarian must be how old? –As we learned on Trivia Today five months ago, a prime number is a whole number whose only factors are 1 and the number itself. For example, the prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. Prime numbers are divisible only by the number 1 or itself. With that in mind, a nonagenarian is a person whose age is in the nineties. The number 97 is the only prime number in the nineties. That’s because 97 is not divisible by any other natural number apart from 1 and 97.

To boast that their age is a prime number, a nonagenarian must be 97 years old. the prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. All their ages are to be considered from the base year.

The difference between the age of A and B is twice the age of B. Difference between the age of B and D is 4 years. The age of E is not less than G’s age and he is 9 years older than H. Difference between the age of C and F is not more than 5 years.

Prime number birthdays should be the same as all other birthdays. So common sense tells me. There’s probably nothing special about those years which are divisible only by one and themselves. But experience tells me differently. It seems to me that prime number birthdays and the years that follow often possess special magic. I’m curious to know if this happens for others?
