Puzzle 1 


I recently gave a new watch to my friend for their birthday.

However, as usual with my presents, it was quite useless as it gains 6 minutes every hour.

I set it using my own accurate clock at midnight, and the watch now shows 8:26am.

I know that it stopped 30 minutes ago, so what is the correct time now?

Puzzle 3 


Yesterday I was asked to buy some stamps.

In the land of BrainBashers, stamps are available in denominations of 4p, 5p, 7p, 12p, and 19p (just the five different values).

For three denominations of stamps, I was asked to buy six of each. For the other two denominations. I was asked to buy ten of each.

Unfortunately, I forgot which I was supposed to buy six of, and which to buy ten of!

Luckily I had been given the exact money required to buy the stamps, £3.50, so the shopkeeper was able to work out the stamps I needed.

Which stamps did I have to buy?
