The Internet is Finding This Math Problem From Singapore Insanely Difficult

If you spent a major part of high school dreading Mathematics, do not read further. Because just when you thought you had left Math behind for good, the Internet decided to throw a curveball your way.

A question based on logical reasoning has stumped netizens across the world after a news presenter from Singapore shared it on his Facebook timeline on April 11:

Everyone on the Internet wants to know - "when is Cheryl's birthday?" Now with everyone sharing, solving, and deliberating on the problem, the question has gone viral and the Facebook post itself has over 5,000 shares.

While Kennethjianwen first mentioned in his post that the question was meant for fifth graders (the reason it probably went viral in the first place), it turned out the Math problem was actually from a Singapore and Asian Schools Math Olympiad (SASMO) paper.

To give you a little perspective, SASMO, primarily a Math competition for the best at the subject, "is  devoted and dedicated to bringing a love for Mathematics to students." Based on this question, we really wonder how.

Kennethjianwen did post an explanation by a Facebook group called Study Room in the comments section, but people still seem to be looking (mostly in vain) for the answer on their own. 

Can you solve this problem? If you do take a crack at it and it leaves you tearing your hair out, just be glad you don't have a friend like Cheryl.
