This problem was from my SAT test on May 7th...which I thought the problem was REALLY easy..(well it looked easy), but I couldn't get it.
The problem
n is a two digit number. If n is divided by 10, the remainder is 9. Also, if n is divided by 7, the remainder is 8. What is n?
All the math brainiacs....answer that one please.

If the remainder is 8, wouldn't you still be able to divide?...

You're not stupid, Fae; the person just has the problem incorrect, although I can't remember the numbers now. But yeah, that person definitely has incorrect numbers in the original problem.

Well does anyone remember the actual problem then? I know the first part is correct...can't remember the second part.

n is a two digit number. If n is divided by 10, the remainder is 9. Also, if n is divided by 9, the remainder is 8. What is n?
n/10 = x r9
n/9 = y r8
n = 89
kthx.

^LOL I figured something in the problem had to be incorrect because you cant get a remainder of 8 when you divide by 7. the remainder would have to be n<7.

Hence the reason Fae was confused.

When you can't figure it out algebraically..just plug in random numbers until you get the desired product..
You knew it was a two digit number and that you would get a remainder of 9 if you decided it by 10. Therefore..it has to be 9 more than a two digit number that ends with 0..so go through the list.
19, 29, 39, 49, 59, 69, 29, 89..like that.
Just a tip. o_O.
