1. $10, $20, or $30? �Q���A�ܤ��A�٬O�ʤ��H

Painter John finished an art work and asking for sale. Peter bought it with $100. But then, changed his mind and returned it back to John for $80. John, then, sold it to Ken for $90.  How much did John earn? 

John's point is that $100 would be paid off the expenses of art tools, time and etc.  He bought it back at $80 and sold it for $90.  He earned $10. Peter thought that when John sold it for $100, he earned $20.  Then, the second time sold for $90, he earned $10. Then, John earned a total of $30.  Ken thought that a $90 art work sold for $100, which John earned $10. Then, he got it at $80, sold it for $90, he earned another $10. John earned the total of $20.  Did John earn $10, $20 or $30?

2. All men are beasts, �k�H���O���~

Assume a=c and b=c, therefore a=b.  �]��a=c��b=c�A�ҥHa=b

now let a is men, b is beasts and c is animals.  �{���]a�O�k�H�Bb�O���~��c�O�ʪ�

men=animals and beasts=animals, therefore men are beasts.

3. All men are interesting, �@�W�S���S�쪺�H

Lets assume men on this planet divide into two groups.  One group with interesting people and the rest are considered uninteresting (or boring).  There is a rule according to the logic: within the uninteresting group, the most uninteresting person will becomes interesting since people are so curious on why he is so boring, what he did daily and etc.  In this case, the second most uninteresting person will become the most uninteresting, then again, move to the interesting group.  On and on, people in this world will be all interesting.

4. 4 Kids �|�Ӥp��

John's cat gave birth 4 kitties. His friends asked him what are the kitties' genders.  John doesn't know but took a guess. The ratio of the male and female can only be 4:0, 3:1 or 2:2.  John guesses 2:2 since the probability of each gender is 50%, therefore the overall gender ratio would be 2:2. What do you think?
