Answer: 68
Find the angle.
Answer: 150 degrees Comment: Guess where I found these questions. No prizes for correct guesses. Nope, it is not the GCE "O" Levels AMaths or Emaths Paper. PSLE MATHS 2009. For the sweets questions, it is solved using simultaneous by subsituition method. Yes, we can solve within 3mins. But for a P6 student who is used to models and not algebra, and under tremendous exam stress, you think he can cope. This sweets quetion was dubbed the most difficult question this year. For angle one, I do not kno how to do. Serious. Some smart people out there to help me solve? Thanks:D
