You must find the ages of nine brothers and sisters in the same family so that:
- There is a triplet and two pairs of twins
- Every age is a prime number
- The sum of the nine ages is 153
- We can build a magic square 3×3 with the nine ages
Another fine math/logic puzzle by Bilbao!
Will give you several days to work this one out; answers to be unmasked Tuesday next week!
