I think the blue eye bit should be the "youngest has blue eyes" and the answer eliminates twins. Thus 2, 3, 6. Also you have the sign reversed. Should be x + y

I think the blue eye bit should be the "youngest has blue eyes" and the answer eliminates twins. Thus 2, 3, 6. Also you have the sign reversed. Should be x + y + z >= 10.

> the answer eliminates twins I don't believe so, because regardless of which child has blue eyes, it doesn't eliminate the possibility that either or both of the other children also have blue eyes. If the statement was qualified with an "only", then you could eliminate twins.
