1 + 4 x 2 = ? .. 10 or 9 ?

I'm a callin' yer bluff .

Oh dear oh dear. I though you may have been a bit of a guru on these mind puzzles, how wrong I was.
Ask an 8 year old.

Ok.
I'll walk you through my process.

A: Can't be correct, because there is no blank yellow face in the unfolded box.
B: Can't be correct, because there is no purple face in the unfolded box.
D: Can't be correct, because there is no purple face in the unfolded box.
C: Meets all the criteria.

D: Can't be correct, because there is purple face in the unfolded box.
C: Meets all the Criteria.

OK... Where is the mistake?

[McDuck]

Initially it thought it was impossible to get the yellow and blue faces joining in that fashion.
But after a second look I saw that you could just flip the box.
If you look at the earlier posts, you will see that this thread is for exactly that, to blow out the cobwebs.
It's not an ego trip.
I suppose it was also let the younger ones show off a bit, sooo I guess it met both criteria.
Ha.

This one is going to show up some holes in the way people reason.


The guard dog barked each time there was an intruder.

The guard dog is barking.

Is there an intruder?

[DrownInside]

A bit tricky, but I agree with this opinion.

[McDuck]

A bit tricky, but I agree with this opinion.

Ha! yes,
Well done you.

I found it rather difficult to hold an assembled image of the box in my head and rotate it till the red side was up.
Aston found it particularly easy, he may have some good talent in that area.
I tested it on some architects, who do shape rotation for a living.. and they had difficulty too.
So, well done Aston.

So, this one may be about comprehension, if English isn't your first language.

The answer is, maybe.

The dog may bark for other reasons.

Perhaps it will bark when it hears a sound outside the fence, or when the owner returns home.

Just because a cause generates a particular effect, that does not mean that an effect will only indicate that cause.

This one will be easy to people used to using the old money.

What's one half minus one third.

in other words,

1/2 - 1/3 = ?

show your working.

Here's one for you McDee

What's going to happen to all the people in motels when the borders reopen next year?

Show your workings in mathematical form.

Lol.

I won't say your 1/6 answer is correct or incorrect, to give other people a chance to dust off those long sleeping, childhood, fraction calculating, brain layers.

Well, we aren't up to the Persian arts of Algebra yet..

So we would be looking at something in the form of,

5x + 2y - 7a x 3B ...... = ?

The variables being, number of spaces, number of people occupying, number of arrivals, number of departures, etc etc.

And probably a more advanced comparative rate of change equation too.

And this is a free flowing equation, the real equation would have bottlenecks and delays.

And a degree of natural self stabilization.

[McDuck]

It's a really interesting question,

You might have to state your original assumptions. (start conditions and parameters)

For example, do you assume the the rest of the world is in semi Covid lockdown,
and is NZ still in Covid free summer,
or does the rest of the world clear through vaccination,
go to summer, and look really interesting to people in NZ I.e, more departures.

You might use Electrical or Charge equations, to get your rough result.
Possibly even build a little electrical circuit, with an electrons representing a number of people.
Capacitors representing the places those people could be, and interconnecting circuits to show how and when they move from one place to another,
That would be fun.
