Singaporean Logical Puzzle Goes Viral: When Exactly Is Cheryl's Birthday?

A math question, originally designed for high school students in Singapore, has stumped thousands across the world since it was posted on Facebook over the weekend. The problem, which was first posted by Singaporean television presenter Kenneth Kong and was initially mistaken for a primary school problem, has been making rounds in various forums stirring debate among adults and children alike.

The unexpected interest that the logical puzzle garnered globally forced the Singapore and Asian Schools Math Olympiad (SASMO) to release a statement clarifying that the question was in fact meant for 14- to 15-year-old participants of the Asian Schools Math Olympiad conducted last week.

“This is a difficult question meant to sift out the better students. SASMO contests target the top 40 percent of the student population and the standards of most questions are just high enough to stretch the students,” the organization said, adding that the clarification was important so that “parents will not worry unnecessarily.”

If you can’t figure out the right answer to the problem that has left the world scratching its collective head, check out this link for the official solution released by SASMO.

And no, the answer is not, as one commentator put it, "Check Cheryl’s Facebook page."
