Why does there need to be four people?

If one person left 3 messages, another left 2 and a third left one message that is a total of 6 messages left by three people.

Hi @ahlam,

The first rule is that at most one person left more than one message. Therefore, there will have to be at least 4 people leaving a message â€” (2) from one person, and then one each for another four.

Hope that helps.
