At the recent BrainBashers Festival, the 100 metres heats were closely monitored.

Each contestant had to run in two races so that the average place could be determined.

Only one runner finished in the same place in both races.

Alan was never last. Charlie always beat Darren. Brian had at least one first place. Alan finished third in at least one of the races. Both Darren and Charlie had a second place.

To explain - since Charlie always beat Darren and Darren had a second place, one race must have been Charlie first and Darren second. Brian therefore won the other race with Charlie second. Since only one runner finished in the same place in both races, this must have been Alan in third. QED.

Puzzle 18

If a hen and a half lay an egg and a half in a day and a half, how many eggs can a hen lay in three days?

[Ref: ZRKN]

Hint: Try doubling the number of hens first.

Answer: 2 eggs.

We are told that:

1.5 hens will lay 1.5 eggs in 1.5 days.

We can double the chickens (which doubles the eggs):

3 hens will lay 3 eggs in 1.5 days.

We can now double the days (which doubles the eggs):

3 hens will lay 6 eggs in 3 days.

We can now divide the number of hens by 3 (which also divides the numbers of eggs by 3).
