Another one to work out.

There are 7 girls in a bus.

Each girl has 7 backpacks.

In each backpack, there are 7 big cats.

For every big cat, there are 7 little cats.

Question: How many legs are there in the bus?

This is not a trick question and no there is no bus driver

I hate to say it but I asked myself that about 10 times (okay, about 47 times).

If you're doing what I was doing you're going from 4090 to 5000 by adding 10.

It's a ripper .

Are you sure

It depends what number you start with. Lets assume 0.

0 (take) - 1000 + 40 +1000 + 30 + 1000 + 20 + 1000 + 10 = 2100 Ain't language fun...

BTW, can't get the 5000 Did get the 4100.

If your answer is 4100 you will have to explain why and show the working out.

X=Take1000and add40to it.. Now add another1000 . Now add 30 .
Add another1000. Now add 20. Now add another 1000
Now add10.

i had time to work it out properly.
dosent anyone know algebra?
Transpose it???????????????????
When using formulae, the BIMDAS rule applies and some operations are performed before other operations. To get the right answer, it is important to get the order of operations right.

-1000= a
+1000=b
+40=c
+30=d
+20=e
+10=f

-a+b+c+d+e+f
=X

(-1 000) + 40 + 1 000 + 30 + 1 000 + 2 + 1 000 + 10=X

there for x= 2 082

where did the 2 come from? Is it a typo?



a + b + C + d + e + f + g + h = x

a= -1000
b= +40
c= +1000
d= +30
e= +1000
f= +20
g=+1000
h= +10

therefore a+b+c+d+e+g+h=2100

It could be a double trick question. Take 1000 is first. then your brain tricks you to add 90 + 10 to get 1000. (assuming the "take" at the start was thrown in as a trick if it wasn't then it's 4100 )


7 girls = 14 legs
7 x 7 x 7 big cats = 1372 legs
7 x 7 x 7 x 7 little cats = 9604 legs

total legs = 10990.............assuming all cats have 4 legs and girls only have 2??? Bet the bus is going to China Town

You see I don't in any way shape or form consider 'take' as a realistic word for an operation in mathematics, therefore I think the assumption that you start with zero and then 'take' 1000 is false. Personally I assume the 'take' to mean 'start with'. Hence I get 4100. If it said subtract 1000 add 40 etc etc then I'd agree with the 2100 result. Using take as a substitution for subtract would be like using give as an alternate to add; just stupid.

Have to agree with you CJW. The correct mathematical operation meaning "subtract" (as I was taught) is "take away". "Take" alone can mean nothing other than "start with", as in "take for example ..."

In any case, if you assume "take" means "subtract" then it's simply an assumption that the initial 1000 would be subtracted from zero. There's no information given as to the starting point so it could be any number! And so all answers are equally likely.

And anyway, I'd never force my tired brain to work out something that a tenth of a cent's worth of silicon can work out for me better and quicker.

Hope you did not write all that out cos you wasted your time.

Even if we assume that "take" means subtract, "Take 1000" Is meaningless as we do not know the starting point. Are we starting at zero? or 1? or 108523489?

It is like asking on this forum "how far is it to Sydney?" when you and I are in different towns. First thing you'd ask is "What, from your house or mine?"

it the type of retarted question youd get in an aptitude test.
this question would be directed at the brain process rather than a answer.
the second question is a bit more of a challenge.

I think you are reading too much into it. The simple/literal meaning is enough for working it out.

that's why it was posted. It shows up that most people will make a simple mistake. I got 5000 the first time I did it, which is sort of expected.

It's all a matter of perspective and context. As Busterwa points out, 'take' can mean subtract/minus. If I 'take' $15 from $40, then yes, mathematically this can be represented as $40 minus $15, and the difference is $25. But the difference is not necessarily the answer, or even a consideration of the question.

From a different perspective: if I 'take' $15 dollars from someone, I now have $15 dollars. So that is +15 to me. I don't care what they started with or how much they have left.

Looking at the context of Rad Lad's poser: He asked you to take 1000; so you have +1000 to start with (not $ unfortunately).

Thus the answer is 4100.
