Singapore high school math problem stumps the Internet
A math problem that first appeared in a test for Singapore’s elite high school students has baffled Internet users around the world after it went viral, prompting a rush of attempts to solve it.
The question, involving a girl asking two boys to guess her birth- day after giving them scant clues, first appeared in an April 8 test organized by the Singapore and Asian School Maths Olympiads (SOSMA).
It was meant for 15- and 16-yearold elite secondary school students, but swiftly went global after a local television news presenter posted it on his Facebook page Saturday.
In the question, Cheryl gives her new friends Albert and Bernard 10 possible dates when they enquired about her birthday, before separately giving each of them further clues.
Test-takers are then asked to use logic to deduce Cheryl’s birthday using a short conversation between the two boys about the information given to them.
By Monday Internet users around the world were posting meticulously detailed answers to the puzzle on social media networks such as Facebook and Reddit, only to prompt a slew of comments disputing their findings and methodology.
