i think that... since 1 brick=1kg... and half a brick is heavy (that's how i read it), that 1 brick would be *too(2) heavy*.

...but obviously that's wrong... ah well, was worth a try, hehe

Each brick weighs 1 Kg and half a brick.....now break this brick.....u will get 2 half bricks weighing 1 kg each....so each brick weighs 2 Kg's

Well, if one brick is 1 kilogram and half a brick heavy, how heavy is half brick?

X= weight of the brick.

X= 1 Kg + 1/2X

X-1/2X= 1 Kg

1/2X= 1 Kg

X= 2 Kg.

Prove:

2Kg= 1 Kg + 1/2(2 Kg)

Isn't it clear?

X= weight of the brick.

X= 1 Kg + 1/2X

X-1/2X= 1 Kg

1/2X= 1 Kg

X= 2 Kg.

Prove:

2Kg= 1 Kg + 1/2(2 Kg)

Isn't it clear?

You cant take the 'and' as a logical operator without rearranging the question

because, "One brick is one kilogram "AND" half a brick heavy"

is NOT "1 brick = (1kilo) X (1/2 brick)"

and its NOT "1 brick = (1kilo) X 1 brick = (1/2 a brick)

it is actually (1 brick = 1 kg) X (1/2 brick) if you take 'and' as logical rather than arithmetic.

because '1/2 brick' is not a proposition, an attempt to take 'and' as a logical (rather than arithmetic) operator falls apart.

lol

applying boolean logic here

One brick is one kilogram "AND" half a brick heavy

1brick = (1kilo) X (1/2 brick) [ 'X' for the boolean operator AND ]

because, "One brick is one kilogram "AND" half a brick heavy"

is NOT "1 brick = (1kilo) X (1/2 brick)"

and its NOT "1 brick = (1kilo) X 1 brick = (1/2 a brick)

it is actually (1 brick = 1 kg) X (1/2 brick) if you take 'and' as logical rather than arithmetic.

Very Heavy.

Says, 1 Brick Is 1 KiloG

Looks like if the cat thinks**1/2 a brick is heavy**

Then a**WHOLE BRICK MUST BE CRIPPLING**.

that's a good one. i approve.

i think that... since 1 brick=1kg... and half a brick is heavy (that's how i read it), that 1 brick would be

too(2) heavy.

Brick - Back to the Logic Puzzles

An old riddle is as follows: One brick is one kilogram and half a brick heavy. What is the weight of one brick (previously: How heavy is one brick)?

(This is a typical elementary math brain teaser.)

If the above contains two statements, then it says that 1 brick is 1 kilogram, and that 1/2 brick is heavy.

If half a brick is heavy, a whole brick must be 2x heavy (regardless of it's actual weight).

2x Heavy could mathematically be written as 2heavy (pronounced TOO HEAVY)

On the other hand, if it is ONE statement, then it says that 1 brick equals 1kg + 1/2 a brick

That means, that 1 brick - 1/2 brick equals 1 kg, and therefor 1 brick must weigh twice 1 kg or a total of 2 kg.

You have all brought up valid arguments about how the question should be interpreted, and valid answers dependent on the interpretation, but I just want to bring up the point that this (and the other daily brain teasers) should (more than likely) be analyzed using the most basic logic possible... again, all of your answers (based on your interpretation of the question) are or could be accurate, but it occurs to me that these "brain teasers" are not meant to cause philosophical debates... so (as I do), these riddles should be examined using the most basic terms possible... right?

Remember this is a riddle not an algebra problem so you need to interpret it as such. To clarify, exchange "one brick" for "a brick" then a normal brick would weigh 2/3 kg.

*This* brick weighs 1 kg but it's 1.5x the normal brick weight. 1 kg = 1.5*Normal_Brick

Normal_Brick = 2/3 kg

On the plus side, since a kilogram is a unit of*mass* not *weight* the answer is the same on the moon.

but if its one kilo and half of itself then it is 1kg coz if its halfing itself it would be halfing its original weight which is 1kg. right? im starting to confuse myself is anyone even adding anything to htese forums?
