As Miss Loi embarks on yet another epic weekend of endless joss sticks sessions, here’s a short and simple and innocent-looking E-Maths problem which had many of her students stumped *scratches head* for you to ponder upon:
Two students Bryan and Joan can complete a science project in 10 hours. If Bryan alone can complete the science project in 15 hours, how long will Joan take to complete the science project by herself?
P.S. This is a serious question ok??? Definitely NOT an April’s Fool joke!
