Tom and Tim, time tested twice troublesome twins, entered the kitchen at ten
o'clock on a Tuesday evening. "Mom, mom, look what I found" said Tom,
waving a sheet of faded paper.
"No, I found it." said Tim.
"What is it, Tom?" Mom asks.
"I don't know, mom, but it talks about Genies."
"really?" she replied as she took the paper from him. It was a copy of the family geneaology she had been looking for so she could do some research. "where was it?"
"It was in that Bible on the mantle." said Tim, "Between page 588 and 589."
"No," said Tom, "it was between pages 1201 and 1202!"
Mom gave Tom a dirty look, and said to Tim, "thanks for finding this sweetie." She looks at Tom.
"Why did you lie to me, Tom?"
How did Mom know that Tom was lying?
"No, I found it." said Tim.
"What is it, Tom?" Mom asks.
"I don't know, mom, but it talks about Genies."

The Geneaology Puzzle Solution
Page 1 in a book is the page just inside the front cover. Page 2 is the other side of the same sheet.Pages 1201 and 1202 are opposite sides of the same sheet of paper, so finding something between these two is highly improbable.

I told Alan and Bert that I had two different whole numbers in mind, each bigger
than 1, but less than 15. I told Alan the product of the two numbers and I told
Bert the sum of the two numbers. I explained to both of them what I had done.
Now both these friends are very clever. In fact Bert, who is a bit of a know it all, announced that it was impossible for either of them to work out the two numbers. On hearing that, Alan then worked what the two numbers were!
What was the sum of the two numbers?

Alan and Bert Puzzle Solution
| Starting Numbers | Sum | Product | Product can also be made using |
|---|---|---|---|
| 6, 5 | 11 | 30 | 10, 3 |
| 7, 4 | 11 | 28 | 14, 2 |
| 8, 3 | 11 | 24 | 6, 4 and 12, 2 |
| 9, 2 | 11 | 18 | 6, 3 and 9, 2 |
As mentioned in the question, he's quite clever - so he looks at the product that would appear if he used each of the four possible combinations. As shown in the table above, the product that appears can also be made from different numbers.
So, he announces that it is impossible for him or Alan to work out what the original numbers were. He seems to be on fairly safe ground.
Alan is a little bit more devious as well as being clever. Armed with this snippet of information he needs to look for a pair of numbers that give a non-unique sum and also give a non-unique product.
11 is the only non-unique sum which always gives a non-unique product. Alan is very clever and very smug.
