Puzzle 2

Yesterday I was asked to buy some stamps.

Stamps, in the land of BrainBashers, are available in 2p, 7p, 10p, 15p and 20p denominations.

For three types of stamp, I was asked to buy five of each.

For the other two types of stamps, I was asked to buy six of each.

Unfortunately, I forgot which I was supposed to buy five of and which to buy six of.

I had been given £3.00, which just happened to be the exact money required, so the shopkeeper was able to work out what stamps I needed.

Which stamps did I buy?

Puzzle 3

Unluckily, last week I lost my measuring tape. It was unlucky as I had to measure Billy's toy box.

Luckily though I could remember that the top had an area of 720 square inches, the side was 800 square inches, and the end was 360 square inches.

What were the true dimensions of the toy box?

Puzzle 4

Many years ago, a cruise liner sank in the middle of the ocean.

The castaways luckily landed on a remote desert island.

There was enough food for the 220 people to last three weeks.

Six days later a rescue ship appeared, unluckily this ship also sank, leaving an additional 55 people stranded on the island to now share the original rationed food.

The food obviously had to be re-rationed, but everyone was now on one-half of the original ration, so how many days in total would the food last for, from the day of the original sinking?
