The Chicken and the Egg

The Puzzler


RAY: Here's the answer. If a chicken and a half can lay an egg and a half in a day and a half, let's double the number of chickens, to three chickens. Because one and a half chickens laid one and a half eggs, three chickens laid three eggs in how long?

TOM: In a day and a half.

RAY: Exactly. So if we have three chickens laying three eggs in a day and a half, then clearly one chicken lays one egg in a day and a half. And two chickens will lay four eggs in three days. So, if two chickens can lay four eggs in three days, then two chickens can lay 32 eggs in 24 days.
