Brain teaser for smart asses

[Chuckup]

What's twice the half of seven and a half?

[wtmusic]

1. It's not seven and a half?

OK, I've been teased.

[GAspnes]

2. that would be 4

[Capn Sunshine]

3. yeah, I'm with you

4

[will work 4 food]

6. according

to the zephyer system, it is 11.366955582

[wtmusic]

4. Could be 10-1/2 too

Answer pleez.

5. Ahhhhh!

It depends on how you read it.

What's (twice the half of seven), and a half

or

What's twice the half of 7 1/2

:evilgrin:

16. Agreed, the answer is either 7.5 or 8

depending on your interpretation of the problem

Twice (the half of seven) and a half:

2<7(.5)>+.5 = 2(3.5)+.5 = 7.5

Twice <(the half) of (seven and a half)>

2<(.5)(7.5)> = 2(3.75) = 7.5

Twice the <(half of seven) and (a half)>

2(.5(7)+.5) = 2(3.5+.5) = 2(4) = 8

or read as

(Twice) *both* the (half of seven) and (a half)

2<.5(7)> + 2(.5) = 2(3.5) + 2(.5) = 7+1 = 8


Both are correct.

You know secretly, deep down inside, you really love math. Go on. Admit it to yourself.

7. Hmm

(Twice) (the half) of (seven and a half)
2 x 1/2 x 7 1/2 = 7 1/2

((Twice) (the half of seven)) (and a half)
(2 x 3 1/2) + 1/2 = 7 1/2

Lets just say, I don't know

[ChoralScholar]

8. uuhh.. maybe

The half of "seven and a half" is half (literally, not mathematically). One Half twice is one.

Is that what you're looking for?

9. Who cares?

My head hurts enough already and you're not helping any.

11. Three and a half and a quarter. Three and a half and a quarter.

Can you push a quarter through a ring? (I mean one that you wear on your finger here)...It's very easy.

[Deja Q]

10. How's this for a smartass answer? (R-rated so now you can guess...)

"The length of my willie?"

2 * (7.5/2) = 7.5, naturally!

As long as it does equal 42 then everything's cool.

[Tom Kitten]

12. so what's the answer?

just wondering

[laconicsax]

13. Not that it matters much...

but what's the expression you're asking?

2(7/2)+(1/2)

2<.5(7.5)>

Both give you 7.5, but I'm just curious.

[Iverson]

14. ambiguity play?

One could also interpret it this way:

2(1/2) x (7 1/2) = 7 1/2

Twice the half becomes a self-negating expression, a waste of time, almost like the brain teasers that we complete with relish.

15. The answer

7 1/2 of course...
