2 Men & 2 Doors – Get Out Alive Riddle

There are 2 men – One of them always tells the truth while the other always tells lies.

There are 2 doors – If you walk though one of them, you stay alive and safe… whereas the other door is dangerous and you die.

Another rendition of this riddle suggests that there are two guards, a truth teller and a lie teller — and these guards are blocking 2 doors which lead to either heaven or hell… whatever your preference…

One door sucks & the other one rules… that’s all you need to know.

You have to walk through one of the doors.

You also have 1 question which you must ask to either one of the men.

What is the question that you ask to either of the men to be sure you know which door to choose in order to stay alive?

Help The Band Cross The Bridge

There are 4 band members that are trying to get to their concert.. they are late – AND – they have to cross a bridge! (don’t worry how this happened .. it just did, ok?)

This riddle is a little more difficult then the “find the heavy egg” … I think I got it from an compsci interview question.

Help The Band Cross The Bridge

The situation:

There are 4 band members that are trying to get to their concert.. they are late – AND – they have to cross a bridge!

(don’t worry how this happened .. it just did, ok?)

If they’re going to make it to the concert on time, they have to cross the bridge in 17 minutes or less.

Here is where it gets complicated:

  • It’s night time and they only have 1 flashlight.
  • The bridge is old and narrow, so only 1 or 2 members can cross at any one time.
    • The flashlight can provide enough light for either 1 or 2 band members, but whoever is crossing the bridge must have the flashlight or be with someone who has the flashlight.
  • They figured out the only way to make this happen is to have 2 people cross the bridge, then send 1 person back with the flashlight.
    • They can’t throw the flashlight.. the bridge is too long (nice try).

Meet the band members:

As stated before, there are 4 band members:

  1. Alex – Vocals – Takes 1 minute to cross the bridge
  2. Mark – Violin – Takes 2 minutes to cross
  3. John – Guitar – Takes 5 minutes to cross
  4. Chris – Drums – Takes 10 minutes to cross

Remember, 2 people can cross at once, but they will go at the slower persons speed!

So if Alex and John go across, it will take them 5 minutes.

If only Mark goes across, it will take him 2 minutes (because he doesn’t have to wait on anyone else).

How can they all make across the bridge in 17 minutes?

The format should look something like this:

Alex and John go across for 5min… Total: 5min

Alex brings the flashlight back for 1min… Total: 6min

Chris and Mark go across for 10min… Total: 16min

etc..

As you can see, with the example started above, it’s already been 16 minutes and there is still someone left on the other side.. they aren’t going to make the concert.

Your turn.. leave your questions, thoughts, and answer in the comments below.. good luck 🙂

SPOILER ALERT: The answer is in the comments below… It is blacked out .. but you can put your mouse over it to reveal it… don’t look if you want to figure it out on your own!

Find The Heavy Egg

Heard this one from the taxi driver taking us from Esfahan to Tehran.

Find The Heavy Egg

There are 8 identical eggs laying on the table (don’t worry about why).

They are all identical in color, shape, smell, etc.. identical in every way except: one of the eggs weighs just slightly more than all the others.

You can’t tell by feeling it in between your hands.. but you do have a scale (no, it’s not digital).  It’s an old-school scale, like this one:

With ONLY 2 WEIGHS – Each weigh can have any number of the 8 eggs on either side.  You must determine which eggs you are going to weigh against each other before putting them on the scale.

YOU ONLY GET 2 ATTEMPTS AT WEIGHING THEM…

How do you find the heavy egg?

Leave the answer below, don’t holler it on Facebook, I want to see who can figure it out =)
