Solution to: Daring Thoughtless Thief Puzzle

A daring, rather thoughtless thief once stole a car of the police chief. The police immediately started an investigation and on the basis of witness depositions, four suspects were arrested that were seen near the car at the time of the crime. Because the chief of police took the case very seriously, he decided to examine the four suspects personally using a lie detector. Each suspect gave three statements during the examinations, as follows:
Suspect A:1. In high-school I was in the same class as suspect C.2. Suspect B has no driving license.3. The thief didn't know that it was the car of the chief of police.
Suspect B:1. Suspect C is the guilty one.2. Suspect A is not guilty.3. I never sat behind the wheel of a car.
Suspect C:1. I never met suspect A until today.2. Suspect B is innocent.3. Suspect D is the guilty one.
Suspect D:1. Suspect C is innocent.2. I didn't do it.3. Suspect A is the guilty one.
With so many contradicting statements, the chief of police lost track. To make things worse, it appeared that the lie-detector didn't quite work yet as it should, because the machine only reported that exactly four of the twelve statements were true, but not which ones.Now the big Question : Who is the thief??


Solution:
There are five statements in which nothing is said about the possible offender: A1, A2, A3, B3, and C1. The statements A1 and C1 seem to be completely contradictory, but that is not the case! Although at most one of these statements can be true, they can also be both false!For example, suspects A and C might only know each other from primary school. About the statements A2 and B3 not much can be said (although it seems unlikely that statement A2 would be false and at the same time statement B3 would be true). In addition, it follows from the introduction that statement A3 is true.On the basis of an assumption about which suspect is the offender, we can count how many of the remaining statements are true:
Statement:
A is the offender:
B is the offender:
C is the offender:
D is the offender:
None of the suspects is the offender:
B1
false

B2

D2

D3

Total:
4 true, 3 false
3 true, 4 false
4 true, 3 false
4 true, 3 false
4 true, 3 false

Combined with the fact that statement A3 is true, this gives:

A is the offender:
B is the offender:
C is the offender:
D is the offender:
None of the suspects is the offender:
Total:
5 true, 3 false
4 true, 4 false
5 true, 3 false
5 true, 3 false
5 true, 3 false

Because it was given that exactly four statements were true, the statements A1, A2, B3, and C1 must be false, and suspect B must be the offender.

Paradox Puzzle


"You cannot prove this sentence is true."

Now, the question is - is that sentence true or false?

.
.
.
.
.
The answer is that this is something of a trick question brainteaser, or a paradox. This can be seen by following through the logic that the sentence is either true or false, and seeing what happens in each case.
If you can prove the sentence is true, then the sentence is false. If you can prove the sentence is false, then it is true. In this way a paradox is created.

What is the solution to the puzzle? Well, there is no direct answer to that as it is a paradox and is self-referential in a way that seems to admit of no true or false answer. One way out is to say that the sentence appears meaningless or has no definite meaning, and get out of the problem by admitting of a potential third possible logical state to a question rather than simply having to have a true or false answer.

Golden Chain Puzzle


The son of a rich bullion merchant left home on the death of his father. All he had with him was a gold chain that consisted of 148 links.
He rented a place in the city center with a shop at the lower level and an apartment at the upper level. He was required to pay every week one link of the gold chain as rent for the place. The landlady told him that she wanted one link of the gold chain at the end of one week, two gold links at the end of two weeks, three gold links at the end of three weeks and so on.
The son realized that he had to cut the links of the gold chain to pay the weekly rent.
 Also consider that when any chain is broken to get links, three links are obtained, two partitions and one link from which chain was broken.

If the son wished to rent the place for 148 weeks, what would be the minimum number of links he would need to cut?

The Adam and the God Guess me puzzle

Adam, God made out of dust
But thought it best to make me first,
So I was made before man
To answer God's most Holy plan.

A living being I became
And Adam gave to me my name.
I from his presence then withdrew
And more of Adam never knew.

I did my Maker's law obey
Nor ever went from it astray.
Thousands of miles I go in fear
But seldom on earth appear.

For purpose wise God did see,
He put a living soul in me.
A soul from me God did claim
And took from me the soul again.

So when from me the soul had fled
I was the same as when first made.
And without hands, or feet, or soul,
I travel on from pole to pole.

I labor hard by day, by night
To fallen man I give great light.
Thousands of people, young and old
Will by my death great light behold.

No right or wrong can I conceive
The scripture I cannot believe.
Although my name therein is found
They are to me an empty sound.

No feat of death doth trouble me
Real happiness I'll never see.
To Heaven I shall never go
Or to Hell below.

Now when these lines you slowly read,
Go search your Bible with all speed
For that my name is written there
I do honestly to you declare.

What Am I?
