The internet is often our first port of call when we’re stumped by a question – but the worldwide web is fighting back with a seemingly impossible brainteaser of its own.
In a maths problem that has divided readers, they are told: Seven men have seven wives. Each man and each wife have seven children. What is the total number of people?
The question in its original form appears handwritten on a piece of headed notepaper bearing the logo of Harvard University.
But the riddle’s unlikely provenance appears to be a 2021 Instagram post by rapper Ja Rule, who claimed it was sent to him by a friend as part of a university ‘interview’ process.

The doubts over the question’s actual origin may come from the fact that different interpretations of its ambiguous wording can result in various answers – at least four, according to internet users.
The wording of the question means there appears to be no definitive answer – although the viral image of the brainteaser includes the handwritten claim that ’90 per cent [of interviewees] were eliminated’.
Even Ja Rule – a Harvard Business School alumnus after completing an online course – claimed to be stumped.
The rapper, who has collaborated with the likes of Jennifer Lopez and Ashanti, posted to his one million Instagram followers: ‘The answers are all over the place lol… solve this problem… What’s the right answer?’
