Thread: Aviation riddles

I'd fill the 5 litre jug to the brim, then use that to fill the 3 litre jug to the brim, leaving me with 2 litres in the 5 litre jug.
I toss out the contents of the 3 litre jug and then pour the 2 litres from the 5 litre jug into the three litre. I refill the 5 litre and then fill up the three litre jug - it already had two litres in it, so only needs 1 litre to fill, leaving me with 4 litres in the 5 litre jug.

How's that one sound oh Lady of the Limerick??

Sounds good Al, well done
Another solution
Fill the 3 liter container and pour it into the 5 liter container. Fill the 3 liter again and then pour it into the 5 liter until it fills up. It should take 2 liters to fill up to the 5 so you should have 1 liter left in the bottom of the 3 liter container. Empty the 5 liter container back into the pool. Pour the 1 liter from the 3 into the 5 liter. Fill up the 3 liter and pour it into the 5 liter. The 5 liter should now contain 4 liters.

BTW, 'The jugs of water' is a logic riddle, a limerick is something completely different.
This is a limerick:

There was a non-rev named Al
who one night went drinking with pals
But he'd forgotten to list
And so he did miss
The roundtrip from Sydney to Cal.


Keep'em flying

The math problem.... what is the solution?

(1. Grab a calculator. (you won't be able to do this one in your head)
2. Key in the first three digits of your phone number (NOT the area code)
3. Multiply by 80
4. Add 1
5. Multiply by 250
6. Add the last 4 digits of your phone number
7. Add the last 4 digits of your phone number again.
8. Subtract 250
9. Divide number by 2

Do you recognize the number?)

and just wondering why this person should run the country too =/

Hi Faux_Leopard, always nice to see another gamer on the board.
So you want the solution to the math riddle, all right but I warn you, it involves that high school algebra you thought you'd never use again.
<UL TYPE=SQUARE>
Key in the first three digits of your phone number (not area code)

Call this number 'x'

multiply by 80

Now we are at 80x.

Add 1.

Now we are at 80x + 1.

multiply by 250.

Now, we are at 250(80x + 1), or 2000x + 250

Add the last four digits of your phone number.

Call this 'y'. So new we are at 20000x + 250 + y.

Add the last four digits of your hone number again.

Now we are at 20000x + 250 + 2y.

Substract 250

Now we are at 20000x + 2y

Lastly divide by 2.

Now we are at 10000x + y

Is it your phone number?

Example
My number is 836-7521 (not really )

1. first three digits- 836

2. 836 x 80= 66,880

3. 66,880 + 1 = 66,881

4. 66,881 x 250 = 16,720,250

5. 16,720,250 + 7,521 = 16,727,771

6. 16,727,771 + 7,521 = 16,735,292

7. 16,735,292 - 250 = 16,735,042

8. 16,735,042/2 = 836-7521---my phone number

The simple explanation---all that multipling, adding and subtracting, is smoke and mirrors

BTW, the 'trick' will work for any seven-digit number.[/list]

Now
Another problem to sink your teeth into

Mystery braintreaser-can you figure out what happened based on the clues?

Randy, was a prisoner who was sentenced to life in prison. He was desperate to get out, (missing the smell of jet fuel in the morning) but the prison was heavily barred and well guarded, making it impossible for him to escape.
Randy has a small dagger (hey, he's from Chicago) with which he could dig a hole into the dirt floor, but the walls of his cell are made of concrete that extend deep into the ground, making a tunnel not a viable option. The only opening is a small skylight in the middle of the ceiling nine feet above. The cell is bare and there is nothing to stand on to reach the celing, yet Randy our hero, manages to escape.
How does Randy do it?

Ok, lets see some answers

Keep'em flying

This may be simplistic but if Randy couldn't overpower his guards with his superior airline customer service skills I would suggest he start digging to pile the dirt up to reach the skylight. That is if it is only 9 feet above the ground. If it is 9 feet above his head we will have to think of another solution.

Coyne you are correct, that is exactly how Randy escaped.

Left brain, right brain test

While sitting at your computer, lift your right foot off the floor and make clockwise circles. While doing this, draw the number '6' in the air with your right hand. Your foot will automatically change directions--interesting isn't it?

I'm not sure if I'm being complimented or insulted?

Thanks for the solution to the math one... the algebra was bugging me...

I am currently a college sophomore and took calculus I this year. Look forward to taking more math, cause I'm weird? I have another riddle... one that took me about a week to reason out but here goes:

Two planes leave at exactly the same time. One plane traveling 400 mph leaves New York and heads towards Paris. The second plane leaves Paris and travels 500 mph and heads towards New York. When the planes meet, which plane will be closer to Paris?
