On Friday I set this puzzle….
A mother takes two steps to her son’s three. If they go out for a walk together, and each starts with their right foot, when will they first step together with their left foot?
If you have not tried to solve it, have a go now. For everyone else the answer is after the break.
Never. After the mother’s first four steps and the son’s first six steps, the two of them will again step together with their right feet. This cycle will then repeat, ensuring that they never step together with their left feet.
Did you solve it?
