Do this calculation - Aussie Stock Forums

1. ## Do this calculation

The instruction that came with this question said "do this in your head, do not use a calculator.

I reckon most here are going to get 5000 as an answer?

OK, then try doing what you have just done in your head on the calculator.

What is happening here?

(PS I have no idea. Neither does the quite smart person who sent it to me).
How is this explained?

The answer is in the wording Julia .......

1000 + 40 = 1040

1040 + 1000 = 2040

2040 + 30 = 2070

2070 + 1000 = 3070

3070 + 20 = 3090

3090 + 1000 = 4090

4090 + 10 = 4100, right?

Same as 300 people crash and die on a plane ....... where do they bury the survivors?

Put 71077345 in your Casio and turn it upside down and read.

I reckon Wayne Swann would get 1052 (with a calculator)

and therefore would run even faster to kill off my family trust.

When I got to the 10, my head said it adds to the 90 and "fills the gap?!" so it went on to the next thousand!

And yes, it is difficult, most cemeteries won't take them!

Unco-operative buggers too, keep sitting up.

What TS said. Have added up the brokerage on too many trades to be caught out on that one.

Did the math, got 4100, but instantly thought it was a trap for people to get 5000.
