These are fropm GMAT Prep I. I took the test about 10 times and worte down each question. After about the 4th time I was getting 49, 50 in Quant because I would get repeats and answer them correctly which would raise my score and give me access to harder questions... but there were always new questions... and I worte them down. So my guess is that questions appearing when you are scoring 50 in quant are in all likelihood 700+ level questions. But notice, many of them look deceptively easy... those are the ones you have to be very careful with...

Hey man,
Will solving this set be a detriment to taking GMATPrep in the end before G-day? I don't want to be solving these if I see the same questions repeat in GMATPrep :). But thanks for compiling them and uploading! For a long time I feared that the 700+ GMAT questions were like the manhattan challenge questions eg: "How many factors of 124600 are not divisible by 6?" This question is a freaking 3 minute+ effort unless one is a genius.

But if the 700+ questions are like the ones in your list then I feel a little better as they are not that bad :)
200 or 800. It don't matter no more.

i think the answer to the manhattan gmat question is all of them coz 3 is not a prime factor of 124600 and so none of 124600's factors will be divisible by 3 and to be divisible by 6 a number has to be divisible by 3. So that is not such a hard one if you know the rule.

However, the problems you'll see are not as easy as they seem especially the DS... be careful. They are very tricky coz they lead you to pick wrong answers. Try a few of the DS and you'll see what I mean.

You will definitely see these on GMAT Prep I if you are doing well.

And if you do see a repeat and you know the answer dock yourself 2 mins.

Also, if you do the final GMAT Prep, 2 months after solving these, you won't remember any of them coz you'll have done so many other problems. But it's up to you.

My bad. Here is the actual question
How many numbers that are not divisible by 6 divide evenly into 264,600?

(A) 9
(B) 36
(C) 51
(D) 63
(E) 72

Definitely not the toughest but unlikely in GMAT
the answer is at the following link

Thanks for the link again. Those questions are good bro:)

Just eyeballing it. My guess is that you'd have to get the prime factors of 264600 and find a way using combinations of counting all the products of 264600's prime factors that don't include a 2 and 3 together... I'll do it and post my answer.

So the primes of 264600 are 2, 2, 2, 3, 3, 3, 5, 5, 7, 7

combinations that don't make 6 are (a) the 2s 5s 7s (b) 3s 5s 7s

(a) 2^3 * 5^2 * 7^2 = 36 combinations
(b) 3^3 * 5^2 * 7^2 = 36 combinations

so total is 72. This rules out A and B

But there are duplicates e.g. the combinations of 5^2 and 7^2 but I don't know how to remove them. So i know the answer is less than 72 and definitely not 9 or 36. So it is between 51 and 63... Intuituvely, 51 seems a little low coz that'd mean there were 21 duplicates so I'd guess the answer to be 63 but I am not sure.

You are right this is a tough one to do in 2 mins coz you have to prime factorize and then do combinations excluding 6 and then remove duplicates = three layers... definitely a question I think I'd solve up till I got to 72 but then I'd be stuck and have to guess...

Yup, but none of the questions in the tough question list you published seem to be as difficult as this one. That makes me feel better :)
