Three Children is a puzzle in the UK version of Professor Layton and the Curious Village.

## Puzzle

The king of an ancient kingdom had three children, A, B, and C.

The difference in age between A and B is three years, while the difference between B and C is two years. A is definitely not the oldest son.

How many possible ways are there to order the ages of the three children?

## Hints

Click a Tab to reveal the Hint.

The difference between A and B is three years, and the difference between B and C is two years.

This means you can rule out the order BAC.

## Solution

### Correct

That's right! There are four possible orders.

A and B are three years apart, while B and C are two years apart, so that rules our BAC.

A may not be the oldest son, but what if A was the oldest daughter? That means you have to include orders where A comes first.
