## The Man With 3 Caskets

You are going to a place called Transylvania for a trip. You meet a man with three caskets. The first one is made of lead, the second one is made of silver and finally third one is made of gold. Now in one of there is a Dracula! And each of these three caskets have an inscription. At most one inscription is true.

You have to figure out, which one the Dracula is in. The following caskets inscription goes like this...

First one is Lead Casket: It says: Dracula is Here

Second one is Silver: It says: Dracula is not Here

Third one is Gold: It says: Dracula is not in the second one

So the question is: Where is the Dracula?

You have to figure out, which one the Dracula is in. The following caskets inscription goes like this...

First one is Lead Casket: It says: Dracula is Here

Second one is Silver: It says: Dracula is not Here

Third one is Gold: It says: Dracula is not in the second one

So the question is: Where is the Dracula?

Hint: If the first casket is true, that would make all 3 true

In the 3rd coffin it says dracula is not in the second one. If this is true, that would lead the second to be true as well. Therefore they all lie and Dracula is in the second one (AKA silver)

YES NO

## The Family Murder Riddle

One evening there was a murder in the home of married couple, their son and daughter. One of these four people murdered one of the others. One of the members of the family witnessed the crime.

The other one helped the murderer.

These are the things we know for sure:

1. The witness and the one who helped the murderer were not of the same sex.

2. The oldest person and the witness were not of the same sex.

3. The youngest person and the victim were not of the same sex.

4. The one who helped the murderer was older than the victim.

5. The father was the oldest member of the family.

6. The murderer was not the youngest member of the family.

Who was the murderer?

The other one helped the murderer.

These are the things we know for sure:

1. The witness and the one who helped the murderer were not of the same sex.

2. The oldest person and the witness were not of the same sex.

3. The youngest person and the victim were not of the same sex.

4. The one who helped the murderer was older than the victim.

5. The father was the oldest member of the family.

6. The murderer was not the youngest member of the family.

Who was the murderer?

Hint:

We know from (3) that the youngest person was not the victim, from (4) that the youngest person was not the helper and from (6) that the youngest person was not the killer. The youngest person can only have been the witness therefore. If we make up a chart there are now three possible combinations:

Oldest person (father) H H M

Next to oldest (mother) V M H

Next to youngest (son) M V V

Youngest (daughter) W W W

(H = Helper ; V = Victim ; M = Murderer ; W = Witness)

We can work out from (5) that the father was the oldest, from (2) that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother.

Of three possibilities: the first is impossible (from (3) the youngest person and the victim were of different sexes); the third is also impossible (from (1) the witness and the helper were of different sexes). Therefore only the second possibility holds and the mother was the murderess

YES NO

Oldest person (father) H H M

Next to oldest (mother) V M H

Next to youngest (son) M V V

Youngest (daughter) W W W

(H = Helper ; V = Victim ; M = Murderer ; W = Witness)

We can work out from (5) that the father was the oldest, from (2) that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother.

Of three possibilities: the first is impossible (from (3) the youngest person and the victim were of different sexes); the third is also impossible (from (1) the witness and the helper were of different sexes). Therefore only the second possibility holds and the mother was the murderess

## Digits From 1 To 9 Riddle

This is what you know:

1. Each letter represents a different digit from 1 to 9

2. The total of each row is 17.

3. (B × B) + B + F = A

4. C × F = EF (a 2-digit number, not their product)

A B C

D E F

What digit does each letter represent?

1. Each letter represents a different digit from 1 to 9

2. The total of each row is 17.

3. (B × B) + B + F = A

4. C × F = EF (a 2-digit number, not their product)

A B C

D E F

What digit does each letter represent?

Hint:

A = 7

B = 1

C = 9

D = 8

E = 4

F = 5

A + B + C = 17

D + E + F = 17

B2 + B + F = A

C × F = EF

To begin with, B has to be a 1 or 2 or else A wouldnt be a single digit. Plug in B = 2, gives you 6 + F = A, meaning F and A can only be (1,7) or (3,9). To get 17, C would have to be 8 or 6, but those values dont work for C × F = EF. So B must be 1.

2 + F = A means F and A can be (2,4), (3,5), (4,6), (5,7), (6,8) or (7,9). To get 17 on the top row, the only option that leaves C as a single digit is F = 5 and A = 7.

C × F = EF

9 × 5 = 45, so E = 4 and D = 8 to make the second row equal to 17.

YES NO

B = 1

C = 9

D = 8

E = 4

F = 5

A + B + C = 17

D + E + F = 17

B2 + B + F = A

C × F = EF

To begin with, B has to be a 1 or 2 or else A wouldnt be a single digit. Plug in B = 2, gives you 6 + F = A, meaning F and A can only be (1,7) or (3,9). To get 17, C would have to be 8 or 6, but those values dont work for C × F = EF. So B must be 1.

2 + F = A means F and A can be (2,4), (3,5), (4,6), (5,7), (6,8) or (7,9). To get 17 on the top row, the only option that leaves C as a single digit is F = 5 and A = 7.

C × F = EF

9 × 5 = 45, so E = 4 and D = 8 to make the second row equal to 17.
