Three Monkeys

Three Monkeys


Three monkeys walk into a motel on the Planet of the Apes and ask for a room. The desk clerk says a room costs 30 bananas, so each monkey pays 10 bananas towards the cost.

Later, the clerk realizes he made a mistake, that the room should have been 25 bananas. He calls the bellboy over and asks him to refund the other 5 bananas to the 3 monkeys. The bellboy, not wanting to make a mess dividing the 5 bananas three ways, decides to lie about the price, refunding each monkey 1 banana, keeping the other 2 bananas for himself. Ultimately each monkey paid 9 bananas towards the room and the bellboy got 2 bananas, for a total of 29 bananas. But the original charge was 30 bananas.


Where did the extra 1 banana go?

    There is no missing banana. This is because the bell boy refunded the monkeys each one banana, leaving 27, not 29. Because the there are three monkeys, each getting refunded one banana, there are two bananas left, so the Bell boy takes those, leaving the three monkeys as only paying 29 originally.

    There isn’t a missing banana. This is because if he refunds the monkeys the amount he did, then it totals up to 27, plus two equals 29. They only paid 29 bananas (bananas as a currency, come on).

  3. The clerk has 30 bananas
    Then, clerk refunds five bananas to the bellmonkey.
    The bellmonkey gives three bananas to the 3 monkeys.
    So at the end,
    The clerk has 25 bananas, since she refunded 5
    The bellmonkey has 2 bananas
    The three monkeys each have 1 banana.
    25+2+3=30.
    So at the end, the clerk has the extra banana.

    Ignore my first comment. There is no missing banana. This is because the bell boy refunded the monkeys each one banana out of the original thirty bananas, leaving 27, not 29. It goes down to 25, because the bellboy took the last 2 bananas.

    There isn’t a missing banana. This is because if he refunds the monkeys one each, then it totals up to 27, instead of 29. Then down to 25 because the evil bellboy took two bananas.

  6. There was no extra bannana because the clerk gave the bellboy 5 dollars plus 25 equals 30 so there wasnt any missing dollar the question and logic is wrong.

    So all three monkeys paid 25 bananas total in the long run so two monkeys paid 8 and 1 monkey paid 9 adding up to 25 meanwhile each money got 1 banana back adding up to 3 plus the original 25 bananas paid then the bellboy monkey had 2 so it adds up to 30 bananas so the missing banana was with the 25 paid

    Clerk: 30-5=25
    Monkeys: 10-9=1
    10-9=1
    10-9=1
    Bellboy: 5-3=2

    If the clerk gave the bellboy 5 bananas from his 30 bananas, the clerk is left with 25 bananas. The bellboy gave the three monkeys 3 bananas, and kept 2 for himself. This means that the extra banana is with the clerk!

    There is no missing dollar. When the clerk refunded the 5 dollars, the three men only paid 25 dollars. Then the bellboy gave them 1 each, adding it up to 28. The bellboy also kept 2 for himself, adding up to 30.

    30b-5b=25b
    25b= owners bananas
    5b-3b=2b
    3b= monkeys bananas
    2b= Bellboy bananas
    25+3+2=30
    30 bananas is the original cost.
    There is no extra banana.

  12. There is no missing bannana because the question and logic is wrong so 5 minus 30 equals 25 so the logic was wrong.

    25+ the 2 from the bell boy equals 27 plus the three back to the monkeys equals 30 bananas.

    There isn’t a missing banana because the monkeys paid 30 bananas. When the store clerk that the bellboy didn’t keep went to each of asked the bellboy to refund the 5 bananas, he kept 25 bananas. Each monkey received one and the bellboy kept the other 2 because “he didn’t want it to be messy”. The other three bananas the monkeys. Therefore there wasn’t a banana missing in the first place.

    There was an original 30 bananas. Then the clerk gave the bell boy 5 bananas which meant that the clerk has 25 bananas still. The bell boy gave the other monkeys three bananas back and the bell boy kept 2 bananas for himself. So there are still 30 bananas.
    25+3+2=30

    The room cost 25 bananas. Each monkey paid 9, 9 times 3 monkeys is 27. The room doesn’t cost 27 it cost 25, so the other 2 are the ones the clerk took. There is no extra bananas.

    The problem is wrong because when it says that the pay 27 bananas, the room doesn’t cost that much. The room only costs 25 bananas so the clerk also gets 2 bananas for himself. And there is no extra banana.
    To prove there is no extra banana you can take 25 bananas and add the three the monkeys got back and then add the two that were left over and it equals 30.

    First, we read the POW really carefully. We got out 33 pens because we wanted to reenact the problem. We used 3 pens to each represent 1 monkey. Then we made 3 piles of 10, since each monkey first paid 10. Then we took 1 pen from each pile, since they were each refunded 1 banana. That makes a total of 27 bananas. Then you subtract 2 since the bellboy had 2 bananas. The confusing information in the POW was that it added the two bananas, which is misleading because you have to subtract it to get the total of 25 bananas, which was the correct price.

    There were 30 bananas.

    5 were taken away, resulting in a total of 25.

    The bellboy kept 2, so there were 3 left.

    Each monkey got 1 of the 3 bananas back.

    You subtract the two bananas that the bellboy got, you get 27. The room was 25 bananas. The difference between 25 and 27 is 2, which is what the bellboy got. So, no bananas are actually missing.

    If the monkeys spent 30 and 3 was returned to them, the monkeys spent a total of 27. The actual price was 25 so the extra 2 went to the bellboy. The 9 that each monkey paid also included the money that the bellboy took.

    The cost at first was 30 bananas. But it was wrong and was supposed to be 25 bananas. So the bellboy had the 5 bananas, and gave 3 to the monkeys. He kept 2. The cost of the room was 25 bananas, and the monkeys paid 27 bananas. The difference between 27 and 29 is 2. Which is the amount the bellboy had. So there really wasn't any missing bananas.

    They all spent thirty, and then three was returned to the whole of them making each one having paid nine, nine times three is twenty seven, the real price was really twenty five and the last two went to the bell boy, s there is no missing bananas.

    In the beginning of this problem originally the monkeys paid 10 dollars each. The clerk then saw that he made a mistake by charging them 30 bananas instead of 25. So what the clerk did was took out 5 bananas and told the bell boy to go and refund the monkeys the extra 5 bananas. The bell boy did not want to make a mess by trying to split 5 bananas amongst 3 monkeys. He decided to lie and only give them 3 bananas each and keep 2 for himself. So the monkeys thought they paid 9 bananas each for the room. They thought the room came out to be 27 bananas. What the monkeys didn’t know was that the bell boy took 2 for himself so they were still overcharged 2 bananas. So if the monkeys would have gotten all of there bananas back, 2 of the monkeys would have gotten 2 bananas and 1 of them would have gotten 1 banana back. 2 plus 2 plus 1 equals 5. 5 plus what the clerk has which is 25 bananas equals 30 bananas.
