    Unlock This!

    Alf's locker is protected by a digital combination lock. It requires Alf to input three two-digit numbers into a keypad. Unfortunately, he has forgotten the combination but, in a rare moment of forsight, he jotted down some clues from which he could deduce it. In common with his alter ego, Alf is sttruggling to work this out. Can you help him? Here are the clues.

    Each of the 3 numbers can be between 1 and 39.
    Each number is different.
    The sum of the first two numbers is 42 (The answer to Life, The U............. etc)
    The last two numbers differ by 2.
    The three numbers are all primes.
    The product of the numbers ends in a number less than 5.
