Math Question (Basic)
 

Okay, I'm trying to figure out how somebody messed up a calculation in a report.

They claim that there are 363, 857 people in Year A, and 422, 495 people in Year B. They then say that the growth is 13.8 percent.

Okay, that's obviously not correct. But how did they come up with 13.8 percent? I'm trying to figure out if they mis-entered a number or if they can't do basic division or what the heck their problem is, but I can't even come up with a scenario that would produce 13.8 percent. Can anyone figure out how a person who's bad at math would come up with that answer?

13.8 percent of all statistics are made up. Maybe they just took a terrible guess.

You lost me around year B.

I ran all sorts of different computations into my calculator, and all I can come up with, is they took a wild stab at it.

This should be the simplest thing ever. I can't figure out how they screwed up, and I need to know.

(422495-363857)/422495

422,495-363,857=58,638

58638/422495=.13878

Dammit you beat me to it! I type too slow.. but in my defense I double checked my answer!

(of course I could delete your post and take all the credit :D)

I'm drinking Scotch. :p

Sadly.. even with bad math they rounded incorrectly... it should be a wrong answer of 13.9%

dammit, you win.

I agree with the n00b.

Ah! So they calculated population growth using the wrong denominator. Brilliant! Rep for everybody in this thread!*

These people are a bunch of idiots. They had no business doing this report that I'm reading, and the very first number in the report is this one, which is calculated wrong.

I did a report on Chiefs planet. Wanna read it?
