this is a P.S.L.E. math question...

this is what a primary 6 (12-year-old) student had to answer in this year's Primary School Leaving Examination (P.S.L.E.) mathematics paper:

"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?"

supposedly, students are now allowed to use calculators for some sections of the math paper (including the one above).

so what do you think?
is this too demanding/difficult for them?

ps: i have to admit it took me quite some time to finally get to the answer *oops* :P
