A ladder hangs over the side of a ship anchored in a port. The bottom rung touches the water. The distance between rungs is 20 cm and the length of the ladder is 180 cm. The tide is rising at the rate of 15 cm each hour.

When will the water reach the seventh rung from the top?

It never will.

The boat and ladder will raise with the water

If you had a 5-litre bucket and a 3-litre bucket, and an unlimited access to water, how would you measure exactly 4 liters?

Fill the 5 litre and pour it into the 3 litre. This will leave you with two litres in the 5 litre bucket. Empty the 3 litre bucket, then pour the two litres from the 5 litre bucket into it. Then re-fill the 5 litre bucket and pour into the 3 litre bucket that now already contains two litres - once this is full, you'll be left with four litres in the 5 litre bucket.

Good one. BFC would have got this instantly if you had changed the nomenclature from water to lager, litres to pints and buckets to 2 pint pots at the HJ.

This reminds we of another HJ puzzle. If you have a pint in one hand, a pint in the other, how do you eat your steak and kidney?

What's the colour of the bear and why?

White. Polar bears because it is the north or south pole
