“Jim bought some chocolates and gave half of it to Ken. Ken bought some sweets and gave half of it to Jim. Jim ate 12 sweets and Ken ate 18 chocolates. The ratio of Jim's sweets to chocolates became 1:7 and the ratio of Ken's sweets to chocolates became 1:4. How many sweets did Ken buy?”
For those who don’t know, the above is one of the questions that appear in this year’s PSLE mathematics exam. Chance upon it in a blog questioning why questions are set so high for this year PSLE. It took me (an engineer!) around 10 mins to read and understand the problem and another 10 to solve it in a NON-examination environment, using simultaneous equations and algebra. To think that the Primary 6 kids have to solve it with the clock ticking and not allowed to use simultaneous equations and algebra, using only model diagrams and unit methods. No wonder kids are so stressed today… Not easy to parents these days.
Btw, the kids this year are allowed to use calculators during the exam. Yeah… like that helps a lot. -_-". Dun ask for the answers to the question. Solve it yourself or click on the link above
