Puzzle 47

-

 

Solution:

First and last chests have treasure in them.


Explanation :

Message 1 says that middle chest has treasure. Since all messages are false, middle chest has no treasre.

Message 2 says that all these chests have treasure. Which means at least one of them does not have treasure (and has poison). Which is middle chest.

Message 3 says that only one of the chests has treasure. As this is false, more than one of the chests have treasure. As middle one has no treasure, the other two - first and last have treasure.

 The question was  What is wrong with this proof ? a=b multiply both the sides by a     --1 a2 = ab  add -b2 to both the side           --2 a2-b2 =ab-b2  factorizing                                --3 (a+b)(a-b) = b(a-b)  divide both the sides by (a-b)    ---4 a+b=b Substituting a with b,              ---5 2b = b Dividing both the sides by b    ---6 2 = 1   The problem is with step 4. When a is equal to b, a-b is zero. You can not divide numbers by zero because division is only defined for non-zero numbers.
