Puzzle 17
Yesterday I was asked to buy some stamps.
In the land of BrainBashers, stamps are available in denominations of 3p, 9p, 11p, 17p, and 21p (just these five different values).
For three denominations of stamp I was asked to buy eight of each, and for the other two denominations I was asked to buy nine of each.
Unfortunately, I forgot which I was supposed to buy eight of, and which to buy nine of!!
Luckily I had been given the exact money required to buy the stamps, £5.00, so the shopkeeper was able to work out the stamps I needed.
Which stamps did I have to buy?
Puzzle 18
Kevin wants to go and see his brother, who lives across the valley, and he wants to take his three pets with him, a dog, a cat, and a mouse.
However, the shortest way to his brother's house involves a river crossing, and Kevin only has a very small boat that can carry him and just one of his pets.
He doesn't want to leave the dog alone with the cat, nor does he want to leave the cat alone with the mouse. However, the dog and mouse are great friends.
How can Kevin cross the river to see his brother, and make sure his pets are all happy?
