Brain workouts

Welcome to brain workouts. For those of you tired of my ufo claims here is some exercises for your brain. The first person to submit the answer and an explanation of how you worked it out is the winner. Simply guessing which one it is wont cut it. You must explain how you came to the conclusion.

Puzzle #1

A wine merchant has six barrels of wine and beer containing: 30 gallons; 32 gallons; 36 gallons; 38 gallons; 40 gallons; 62 gallons

Five barrels are filled with wine and one with beer. The first customer purchases two barrels of wine; the second customer purchases twice as much wine as the first customer.

Which barrel contains beer?

2 lots of wine,one being double the amount means the quantity should be divisible by 3. The only way I seem to be able to manage that is to exclude the 40 gallon barrel,so my answer is the 40 gallon barrel contains the beer.

Customer #1 bought 2 barrels @ 66 gallons wine => 30 + 36

Customer #2 bought 3 barrels @ 132 gallons wine => 32 + 38 + 62

Barrell of Beer = 40 Gallons

Okay here is another brain workout.

Puzzle #2

Mr Carter, Mr Butler, Mr Drover and Mr Hunter are employed as a carter, a butler, a drover and a hunter. None of them has a name identifying their profession. They made four statements:

1. Mr Carter is the hunter.

2. Mr Drover is the carter.

3. Mr Butler is not the hunter.

4. Mr Hunter is not the butler.

According to those statements, the butler must be Mr Butler, but this cannot be correct. Three of the four statements are untrue. Who is the drover?

Mr Carter is the Drover

Mr Butler is the Carter

Mr Hunter is the Butler

Mr Drover is the Hunter

T/F statement 3 is correct

and Mr Carter is the drover

Puzzle #3

A man goes into a bar in Melbourne. "Glass of beer" he says to the bartender. "Light or special?", asks the bartender. "What's the difference?", asks the man. "Light is 90 cents, special is $1" replies the bartender. "I'll have the special", says the man, placing the $1 on the counter.

Another man comes into the bar. "Glass of beer please" he says, placing $1 on the counter. The bartender gives him the special.

How does the bartender know he doesn't want the light?

Because he's Richo? 🙂

Re: Brain workouts

ufo_investigations — Sat, 12 Apr 2014 01:04:07 GMT

sorry but Richo wasn' there.

The money was in loose coins. If he'd wanted light he'd have put down 10c less.

he knew the price and didn't proffer the correct change for a light beer. He put down $1 inferring that was the beer he wanted.

Correct! 🙂

Man 1. put down $1 coin

Man 2. put down 50 cents, 2 x 20 cents and 10 cent coin. therefore is was obvious he wanted the special.

how do you know that from the info given?

That's how the bartender knew that man 2 wanted the special. If man 2 put down a $1 coin that would have caused doubt in the bartender as he could want to buy the 90 cent beer and get 10 cent change, but because he put down 50 cents, two 20 cents and a 10 cent coin, the bartender was absolutely sure he wanted the more expensive beer, the special.

Re: Brain workouts

cq_tech — Sat, 12 Apr 2014 02:21:06 GMT

Man 2 could also have put down 4 x 20c and 2 x 10c coins, or even 20 x 5c coins for that matter (amongst many other combinations).
