#### a group of astronauts

###### Problem Solving

12 has prev. experience.
9 doesn't have experience.

12*9*8=864.

I think this is the answer, not 100% sure.

#### GPREP

###### Data Sufficiency

One of the equation is m-j=2m-2k. We can rewrite it as m+j=2k.

statement 1: j=30k. We can't solve the equation with j=30k, therefore insufficient.

statement 2: k=40k, we can solve m+j, which is 80k.

avg.=(40k+80k)/3=40k, therefore sufficient.

#### (C) 2008 GMAT Club - [t]v01#37[/t]

###### Sentence Correction

I don't think E is correct, because the second part of the sentence is an incomplete sentence. blah blah blah; especially Nikola Tesla, who blah blah (modifier). If I take out the modifier, the second part becomes "especially Nikola Tesla", which doesn't have a verb. As for A, such as = examples. Ni...

#### 0-10 X

###### Data Sufficiency

I don't see how statement 1 is sufficient.

If z is 9 and x is 8, then we have...

9>(8+10)/2?
9>9?

no....

Did I miss something?

#### Diesel engines

###### Sentence Correction

In C isn't "they" ambiguous?

"They" can refer to diesel engines or gasoline engines?

I would choose B, but not 100% sure the answer.

#### Unable to identify assumption of this GMATPrep Question

###### Critical Reasoning

I actually stuck between A and B then crossed out B.

I actually thought B weakened the argument, because if it's not normally concentrated, then Shanon can't make a generalized statement?

#### Remainders

###### Problem Solving

The question is basically asking us a number that is multiple of 6. I use multiple of 6, because 6 is the next highest divisor that can actually result in a remainder of 5. That leaves us with 30 and 66. 30=6*5 (this is basically prime factorization, but I didn't break up 6, because the question is ...

#### GMAT Prep CAT-1 Question

###### Data Sufficiency

C:W:M
2 5
5 W 11

the ratio of 2/5=5/W

25=2W

W=25/2

C : W : M
5 25/2 11

We can't have a fraction of people, so we mutiply the whole ratio by 2.

C : W : M
10 25 22

I hope this helps, please correct me if I made a mistake.
