OG 11 Log for hard/medium questions ?

by smar83 » Sun Jan 06, 2008 8:33 pm
Folks,

I saw eric has log of hard/medium question for OG10. Anything for OG11 ? Any link/source for errors on OG11 ?

Question no. 14 on Pg.154, the answer to this question is a bit controversial. I personally chose 1 has ( 1-1) would give you 0 in the denominator making the equation invalid.
The answer says 0, I dont know why/how.

thanks.

Unfortunately, no similar log has been created for OG11 to the best of my knowledge. I've been looking for such a document for almost two years now.

smar83,
I feel that the mistake you are doing is substituting the answer choices for x, when the question is asking or the value of 1/(x-1).

Only a fraction that has numerator = 0 can have value = 0. So 1/(x-1) will be undefined. So, 0 is the correct choice.
