1. The mean of four numbers is 12. Three are 7, 11 and 14. What is the fourth?
   Show explanation

   16. The total must be 4 x 12 = 48. The known numbers sum to 32, leaving 16.

2. A three-digit lock code uses 2, 5 and 8 exactly once. It is greater than 500 and less than 800. Its final digit is even and smaller than its first digit. What is the code?
   Show explanation

   582. The first digit must be 5. The final digit must be even and below 5, so it is 2. The middle digit is 8.

3. You have 4 distinct books. Two particular books must stay next to each other, in either order. How many different left-to-right arrangements of all four books are possible?
   Show explanation

   12. Treat the adjacent pair as one block. Arrange that block and the two other books in 3! = 6 ways. The block has two internal orders, so 6 x 2 = 12.
