Thinking Thursdays – Riddles and Brainteasers

It’s time again for our Riddles and Brainteasers post for the month. Last month’s post really got your brain working out. Hopefully, today’s questions have you testing your mental agility again! As usual, we will post the 10 riddles below, then the answers, with a graphic separating the two, so hopefully you will notice if you start to scroll too far (but I won’t tell anyone if you cheat and peek at the answers!)

Don’t forget to tell us in the comments how you did!

  1. One sunny afternoon, three men go for a ride on a hot air balloon over the Sahara desert. An hour into the trip, the balloon begins to lose altitude. A month later, someone found one of the ballooners laying on the desert sand dead, naked, and holding half a toothpick. What happened to him?
  2. A donkey travels a certain distance each day. Strangely enough, two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles. It would seem that two of the donkey’s legs must be one mile ahead of the other two legs, but of course this can’t be true. Since the donkey is normal, how is this situation possible?
  3. Some say we are red, some say we are green. Some play us, some spray us. What are we?
  4. As I was going to St. Ives, I met a man with seven wives. Every wife had seven sacks, every sack had seven cats. Every cat had seven kittens. Kittens, cats, sacks, and wives, how many were going to St. Ives?
  5. The king dies and two men, the true heir and an impostor, both claim to be his long-lost son. Both fit the description of the rightful heir: about the right age, height, coloring and general appearance. Finally, one of the elders proposes a test to identify the true heir. One man agrees to the test while the other flatly refuses. The one who agreed is immediately sent on his way, and the one who re-fused is correctly identified as the rightful heir. Can you figure out why?
  6. A mother has three sick children. She has a 24-ounce bottle of medicine and needs to give each child eight ounces of the medicine. She is unable to get to the store and has only three clean containers, which measure 5, 11 and 13 ounces. The electricity is out and she has no way of heating water to wash the containers and doesn’t want to spread germs. How can she divide the medicine to give each child an equal portion without having any two children drink from the same container?
  7. A wealthy wise old woman feared that her daughter was lazy and as a result rather stupid. When the old woman died, her will stipulated that her assets were to be liquidated and a check was to be written for the full amount. The check was to be placed in one of three envelopes. The other two envelopes would contain a blank piece of paper. If the daughter could determine from the writing on the envelope which envelope contained the check, she would inherit her mother’s fortune. Otherwise, the fortune would go to the old woman’s favorite charity for animals. The daughter was not allowed to touch the envelopes. Her decision had to be made based on the writing on the envelopes. The daughter was told that only one envelope had a true statement and that the other two statements were false. The envelopes had the following writing: 1. This envelope does not have the check 2. This envelope has the check 3. The second envelope does not have the check. Which envelope should the daughter pick?
  8. Jack has 8 bricks. 7 of them weights the same amount and one is slightly heavier. Using a balance scale, how can Jack find the heavier brick in two weighings?
  9. What word starts with E and ends with E but only has one letter in it?
  10. A bus driver goes the wrong way on a one-way street. He passes the cops but they don’t stop him. Why?

The Answers

  1. As the balloon lost altitude, the men took off their clothes and threw them overboard to decrease the weight of the balloon. The balloon continued to drop so the men drew straws to see who would be forced to jump. The dead man in the desert drew the shortest one (the half toothpick).
  2. The donkey operates a mill and travels in a circular clockwise direction. The two outside legs will travel a greater distance than the two inside legs.
  3. Pepper
  4. One. The man, his wives, sacks, cats, and kittens aren’t going anywhere.
  5. The test was a blood test. The elders remembered that the true prince was a hemophiliac.
  6. Fill the 5 oz. and 11 oz. containers from the 24 oz. container. This leaves 8 oz. in the 24 oz. bottle. Next empty the 11 oz. bottle by pouring the contents into the 13 oz. bottle. Fill the 13 oz. bottle from the 5 oz. container (with 2 oz.) and put the remaining 3 oz. in the 11 oz. bottle. This leaves the 5 oz. container empty. Now pour 5 oz. from the 13 oz. bottle into the 5 oz. bottle leaving 8 oz. in the 13 oz. bottle. Finally pour the 5 oz. bottle contents into the 11 oz. bottle giving 8 oz. in this container.
  7. The daughter should pick envelope 1. If the check was in envelope 2, statements 1 and 2 would both be true. If the check was in envelope 3, statements 1 and 3 would both be true. If the check was in envelope 1, that would make statement 1 false, statement 2 false and statement 3 is the only true statement, making it the envelope with the cheque.
  8. First he split them in to piles of 3, 3, and 2 bricks. Then he weighs both groups of 3 with each other. If they balance he knows the brick is one of the 2 unweighed bricks and he can weigh them to find the heaver one. If the the stacks of 3 bricks do not balance, he will weigh 2 of the 3 bricks. If they balance he will know the brick left unweighed is heavier, or if they do not balance, he will find the heavier one.
  9. Envelope
  10. He was walking.

Thinking Thursdays – Riddles and Brainteasers

It’s time again for our Riddles and Brainteasers post for the month. Last month’s post really got your brain working out. Hopefully, today’s questions have you testing your mental agility again! As usual, we will post the 10 riddles below, then the answers, with a graphic separating the two, so hopefully you will notice if you start to scroll too far (but I won’t tell anyone if you cheat and peek at the answers!)

Don’t forget to tell us in the comments how you did!

The Questions

  1. When John was six years old, he hammered a nail into his favorite tree to mark his height. Ten years later at age sixteen, John returned to see how much higher the nail was. If the tree grew by five centimeters each year, how much higher would the nail be?
  2. I am four times as old as my daughter. In 20 years time I shall be twice as old as her. How old are we now?
  3. There is a lily pad in a small pond. The lily pad doubles in size each day. On the 20th day, it covers the whole pond. On what day was the lily pad  half the size of the pond?
  4. Which word is the odd one out?
    Seventy Brawl
    Clover Proper
    Carrot Swing
    Change Travel
    Sacred Stone
  5. You want to boil a two-minute egg. If you only have a three-minute timer (hourglass), a four-minute timer and a five-minute timer, how can you boil the egg for exactly two minutes?
  6. What has five wheels, though most people think of it as having only four. You cannot use it without that one wheel more, you can put things in it, you can strap things on top, You can’t find it in the market, but you can still go shop. What is it?
  7. If you were to spell out every whole number (in English), how high would you have to count before you would use the letter A?
  8. There is a certain club which is for men only. There are 600 men who belong to this club and 5% of these men wear one earring. Of the other 95% membership, half wear two earrings and the other half wear none. How many earrings are being worn in this club?
  9. A 300 ft. train is traveling 300 ft. per minute must travel through a 300 ft. long tunnel.  How long will it take the train to travel through the tunnel?
  10. You are standing in front of a room with one lightbulb inside of it. You cannot see if it is on or off. Outside the room, there are 3 switches in the off positions. You are allowed to flip whatever switches you want but can only enter the room once. How can you determine which switch controls the lightbulb?


The Answers

  1. The nail would be at the same height since trees grow at their tops.
  2. I am 40 and my daughter is 10. (In twenty years, I will be 60 and she will be 30)
  3. Day 19.  Most will say day 10, but that is incorrect because on day 20 the lily pad will have  doubled from day 19, so 19 must be half the size of the pond.
  4. Carrot. When the first and last letters are removed from the other words, they still spell another word.
    Seventy -> Event Brawl -> Raw
    Clover -> Love Proper -> Rope
    Swing -> Win Change -> Hang
    Travel -> Rave Sacred -> Acre
    Stone -> Ton
  5. Once the water is boiling, turn the three-minute timer and five-minute timer over. When the three-minute timer runs out, put the egg in the boiling water. When the five-minute timer runs out, two minutes have elapsed, and it is time take the egg out of the water. You don’t need the four-minute timer for this riddle.
  6. A car
  7. One thousand
  8. Six hundred. We know that 5%, or 30 of the men are wearing one earring. Of the other 95%, or 570, we know that half are wearing two earrings and the other half none. This is the same as if they all wore one.
  9. 2 minutes. The front of the train will make it through the tunnel in one minute, but the back of the train will just be entering the tunnel. It takes another minute for the back of the train to exit the tunnel.
  10. You turn 2 switches “on” and leave 1 switch “off” and wait about a minute. Just before you enter the room, turn one switch from “on” to “off”. Once in the room, if the lightbulb is on, it is obviously the switch that is still “on”. If the lightbulb is cold, then it was the switch that you never touched. If the lightbulb is off, but warm to the touch, it must be the last switch you turned off right before you entered the room.

The Answers

  1. A map
  2. The letter R
  3. Heroine (He, Her, Hero, Heroine)
  4. Four sisters and three brothers
  5. ENT (One, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten)
  6. Your name
  7. Follow these steps:
    1. Fill the 3L jug (3L jug has 3L of water in it, 5L jug is empty).
    2. Transfer the water in the 3L jug to the 5L jug (3L empty, 5L has 3L of water in it).
    3. Fill the 3L jug again (3L jug has 3L of water, 5L jug has 3L of water in it).
    4. Transfer water from the 3L jug to the 5L jug until the 5L jug is full (5L jug is now full, 3L jug has 1L water that would not fit in the 5L jug).
    5. Dump out the 5L jug (3L jug still has 1L of water, 5L jug is now empty)
    6. Transfer the 1L of water in the 3L jug to the 5L jug (3L jug is now empty, 5L jug has 1L of water in it.
    7. Fill the 3L jug (3L jug has 3L of water, 5L jug has 1L of water in it).
    8. Transfer the water from the 3L jug into the 5L jug (3L jug is now empty, 5L jug now has 4L in it!)
  8. Queue
  9. 2. 11 o’clock plus 2 hours = 1 o’clock, so 9 o’clock plus 5 hours = 2 o’clock
  10. Ace of Diamonds, King of Hears, Two of Spades
    • (Explanation: It’s easiest to figure out the Suits order then the card number. Both the diamond and the heart are to the left of the spade, so spade is in Position 3. Because there is an ace to the left of the heart, the heart cannot be in Position 1, meaning it must be in Position 2, leaving the diamond in Position 1. Next, work on the order of the card numbers. We already know that the ace is to the left of the heart (which is in position 2), so the ace must be in Position 1. And since the two is to the right of the king, the king must be in Position 2 and the two must be in Position 3).
