The puzzle, shared by user @ellis_puzzles, reads: “When I was 2, my sister was twice my age. Now I’m 30. How old is my sister?” This simple question has sparked a range of responses, both thoughtful and humorous, with users debating the solution in the comment section.
One user confidently responded, “32. When you were 2, your sister was 4. She’s 2 years older than you.” Another chimed in with, “This is so dumb. No one will get this wrong. 32!” The comments continued with a touch of humour, with one user joking, “She’s 25… she’ll remain 25 until her 45th birthday.” Clearly, even a straightforward puzzle can bring out the comedic side of social media.
A fourth user admitted that maths might not be their strong suit but offered the same answer, saying, “Maths was never my forte, but if she was 4 when you were 2, then she would be 2 years older than you. Therefore, she’s 32 now.”
