A school maths question posted on Facebook by a Singaporean TV presenter has stumped thousands, and left many asking if that’s really what is expected of Singaporean students.
The question asks readers to guess the birthday of a girl called Cheryl using the minimal clues she gives to her friends, Albert and Bernard.

Cheryl’s Birthday was initially reported to be an examination question for 11-year-olds.
Students stressed by tough examinations is a perennial issue here, and Cheryl’s Birthday reignited concerns that the education system was too challenging.
