  • Here you see a pool with six happy frogs. You must exchange the positions of the brown and green frogs, using the following rules:

    a frog can only jump to an empty water lily;
    a frog can only jump over at most one other frog, that has another color;
    a frog can only jump forward (so the green frogs jump right and the brown frogs jump left).

    How can this be done?

  • Jacob jumped off the top of building a suicide attempt not knowing that a safety net is already there near the 8th floor. However, he was interrupted by a bullet shot at the back of head fired near the 10th story window. Alexis falls on the safety net but was dead at the instance.
    Normally, if a person intends to commit suicide and his actions cause his death, it is a suicide even if the death does not take place in the way the person expected.
    But if it’s not the bullet Jacob must have survived.

    Later on, investigating police found out that a man angrily fired at her wife in the 1oth floor flat. however, shot missed the wife and hit the Jacob.
    Normally, when a person intends to kill one human being and by his action kills another human being accidentally, the charge is murder.

    Later on the investigation, it was found out that gun was always unloaded and the man is just threatening his wife, Further investigation revealed that the shotgun had been loaded by the couple’s adult son, who was angry at his mother for cutting off monetary support. The son was hoping one day his father accidentally kill his mother
    Normally, when a person plans something whose action kills another human being, the charge is murder.

    Is this a murder or suicide and if murder who is guilty?

  • Santa is getting ready – sorting presents, filling sacks and working out his route to make sure he can deliver all his wonderful presents. The trouble is, every year just before Christmas, the reindeer have nothing to do and mostly stand around getting rather bored. They are always asking if they can help but there’s nothing they can do until Santa’s ready to go.

    This year, Santa is prepared for them and he’s set them a little challenge to help keep them busy. He’s given them the following problem:

    Five children from five different families living in five different counties of England have asked for a different gift each. From the clues, the reindeer have to work out who’s who, where each child lives and what present each has asked for. The first reindeer to solve the problem gets an extra portion of Christmas pudding on Christmas Day!

    1. Neither Cliff, nor Jennifer Feather (who does not live in Yorkshire), lives in Kent.

    2. Young Crawford, who is neither Sarah nor Cliff, asked for the pony (a gift that Santa would have particular difficulty getting down the Crawford family’s chimney!).

    3. Young Rowlands is neither the child who lives in Yorkshire nor the child who has asked for a bicycle.

    4. The gift due for delivery to Cornwall, which is not for the child surnamed Rowlands, is a computer.

    5. Liz, who has asked for the painting set, is not from Kent. Her surname is not Jamison.

    6. The child who lives in Essex has asked for a guitar. Alan lives in Cumbria.

    Children’s first names : Alan, Cliff, Jennifer, Liz, Sarah
    Children’s last names : Crawford, Feather, Jamison, Northey, Rowlands
    Counties : Cornwall, Cumbria, Essex, Kent, Yorkshire
    Presents : Bicycle, Computer, Guitar, Painting Set, Pony

  • You met three Monsters. One always tells the truth, other one always lies and the last one alternates between lie and truth.
    Monster 1: You may ask us one question, then you must guess which dragon is which
    Monster 2: He is lying. You may get three questions
    Monster 3: Oh no It is definitely one question
    You asked the first Monster a question
    You: What would the second Monster say if you were to ask it if the 3rd dragon had been lying when it agreed with the first one that you could ask only one question
    Monster 1: He’d say, “Yes, the 3rd Monster was lying”
    Then you asked a second question addressing the three Monsters…… But they remained silent.
    And, you solved the puzzle in 90 sec.
    So, which dragon is which?

  • Paul, Sam and Dean are assigned the task of figuring out two numbers. They get the following information:

    Both numbers are integers between (including) 1 and 1000

    Both numbers may also be identical.

    Paul is told the product of the two numbers, Sam the sum and Dean the difference. After receiving their number, the following conversation takes place:
    Paul: I do not know the two numbers.
    Sam: You did not have to tell me that, I already knew that.
    Paul: Then I now know the two numbers.
    Sam: I also know them.
    Dean: I do not know the two numbers. I can only guess one which may probably be correct but I am not sure.
    Paul: I know which one you are assuming but it is incorrect.
    Dean: Ok, I also know the two numbers.

    What are the two numbers?
