Answer:
John, Tom, Andy
Explanation:
We should carefully read this to get to an answer. To make it easier we are going to use letter T for Tom’s age, J for John’s and A for Andy’s
It first says “Tom is younger than Andy” meaning Andy is older than Tom. So, it is A>T. For now, the ranking might be 1) Andy, 2) Tom.
Then it says „John is not older than Tom” meaning, Tom is older than John. As we set number 2) for Tom, and John is younger, this will be T>J, meaning 3)John.
Seeing this backwards, from younger to older, as the questions says, the rank will be: J<T<A, John (youngest), Tom (middle one), Andy (the oldest)
