Puzzle Details

A hen and a half will lay an egg and a half in a day and a half.

How many eggs would six hens lay at the same rate in six days?

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 double the chickens again:

6 hens will lay 6 eggs in 1.5 days.

We can now multiply the number of days by 4 (which multiplies the number of eggs by 4).

Therefore 6 hens will lay 24 eggs in a 6 days.
