Problem Of The Week 38

with 2 comments


My grandson, my son, and i share the same bday, this year all 3 of our ages have become prime numbers. i remarked to my son that For the last 17 years prior to this year, whenever your age was a prime number, so was mine and vice versa. “yes” he replied and said that 17 years from now, i will say to my son, for that last 18 years prior to this year, whenever your age was a prime number so was mine. How old are we?

  1. Pretty easy once you list all the primes below 100. The ages of you, your son and your grandson are 67,37 and 13 respectively.Never knew you grew so old!:p
