今天看到yahoo头条说几天前的2009年新加坡小学毕业考(俗称PSLE)的数学题“极难”，导致家长学生叫苦不迭。
我在网上找了一下今年的题目，发现的确是难，新加坡小学也是不教代数的，不可以设X。
大家有兴趣的话看看吧。这只是小学毕业考试，看来新加坡的孩子也是没有童年的那种。


这个是著名的被头条登出的Jim和Ken的问题。
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?.
Ans: 68 sweets

下面这个自行车的问题也难，
Mei and Lin were in a bicycle race. Mei was travelling at a constant speed of 20km/hr and they both did not change their speed. When Lin completed half the race, Mei was 3.5km ahead. Mei completed the race at 10.45am. What time did Lin complete the race?
Ans: 11.06am


下面几道题还算可以，但整个paper整体难度的确很高。
Sally baked some cookies to sell. 3/4 of them were chocolate cookies and the remaining were almond cookies. After she sold 5/6 of chocolate cookies and 210 almond cookies, she had 1/5 of the cookies left. How many cookies did she sell?
Ans: 960

6 friends decided to rent computers from 2pm to 4.30pm. While 4 of them were playing, the other two would watch. If the cycle continues, and each of them played for equal number of minutes, how many minutes will each person get to play?
Ans: 100 minutes

如图：ABCD是正方形，GH平行于AD，EF垂直于GH。现在知道FG=FE=FH。求角GEH的大小

当然，现在国内00后的小学生是怎样的，我也不清楚。反正有一点是肯定的，从小学就互相攀比名牌，比谁知道的车牌子多。

你只能画方块，连改成线段都不可以。

原因是我用国内的方法做，当时已经尽量考虑到这种差异性，所以完全不跳步，每个步骤都写的非常仔细。但没用，就是批你错。

当然大学里没这个问题。

小豆兄，为了您的孩子的未来，要早作打算啊。
