出道智力测验题,换换脑子:
有三名乘客,姓张、李、赵。恰巧火车司机,乘务员、乘警也姓张、李、赵。但我们不知道谁姓什么。我们只知道:
1 姓张的乘客住在北京。
2 乘警住在北京与天津之间。
3 与乘警同姓的乘客住在天津。
4 住家离乘警最近的乘客月薪是乘警月薪的整三倍。
5 姓李的乘客月薪是1000元。
6 在火车上工作的赵氏最近打保龄球击败了乘务员。
问火车司机姓什么?
以上6条已知情况虽然没有关系,但用逻辑排除法可以得出答案。

没有做廖康的题,不过也有一道题分享:
一群外星人来到地球上。外星人中女性的特征是一只脚比另一只脚大一号儿,男性则两只脚一样大。他们一群外星人一起去买鞋,最后发现剩了一只36号和一只45号的鞋,问这群外星人最少有几人? - posted on 03/22/2009

我特喜欢做这种题。好久没做了,这次花了12分钟(觉得题目不是很清楚)。
以前做过这个 Einstein Problem,花了一晚上。现在脑子不太好使了。
Facts:
1: There are 5 houses in 5 different colours.
2: In each house lives a person with a different nationality.
3: These 5 owners drink a certain beverage, smoke a certain brand of cigar and keep a certain pet.
4: No owners have the same pet, smoke the same brand of cigar or drink the same drink.
From the following information, can you determine WHO KEEPS FISH?
1: The Brit lives in a red house.
2: The Swede keeps dogs as pets.
3: The Dane drinks tea.
4: The green house is on the left of the white house.
5: The green house owner drinks coffee.
6: The person who smokes Pall Mall rears birds.
7: The owner of the yellow house smokes Dunhill.
8: The man living in the house right in the centre drinks milk.
9: The Norwegian lives in the first house.
10: The man who smokes Blend lives next to the one who keeps cats.
11: The man who keeps horses lives next to the man who smokes Dunhill.
12: The owner who smokes Blue Master drinks beer.
13: The German smokes Prince.
14: The Norwegian lives next to the blue house.
15: The man who smokes Blend has a neighbour who drinks water.

对,说出推理更重要。下礼拜出个难的。 - Re: 智力测验posted on 03/22/2009
记错了,做了一晚的不是这题,是另外一题,等我找出来。当时我刚认识我先生,他写了个程序来算那题的答案,电脑算了一整晚。
现在我的记性真的是太差了。我儿子记性可好了。说过什么话,当时没觉得他听了记了,过了好几天他突然说出来给我。才两岁。 - posted on 03/23/2009
找到了:Self-Referential Aptitude Test
Date: Thu, 14 Dec 1995 15:03:28
From: Jim Propp
Subject: Self-Referential Aptitude Test
A few years ago I wrote a "Self-Referential Aptitude Test" as part of a
longer chain of puzzles. Since this puzzle seems to have taken on a life
of its own and has been spreading around various parts of the 'net, I
figure I might as well post it to silent-tristero before someone else
does. Feel free to pass it on (with attribution).
The solution to the puzzle is unique, and in some cases the knowledge that
the solution is unique can actually give you a short-cut to finding the
answer to a particular question, but it's possible to find the unique
solution even without making use of the fact that the solution is unique.
(Thanks to Andy Latto for bringing this subtlety to my attention.)
I should mention that if you don't agree with me about the answer to #20,
you will get a different solution to the puzzle than the one I had in mind.
But I should also mention that if you don't agree with me about the answer
to #20, you are just plain wrong. :-)
