thanks Brent.

when we say x divides y evenly, can it also mean that y is even no?

No, we can't conclude that y is even. For example, we could say that 3 divides evenly into 15.

As I said, though, an official GMAT question would never say "divides evenly into"

Cheers,

I can't assure you, but I feel it's redundant.

You are already specifying whom you are referring to by the usage of 'who'. So, that makes the usage of those redundant.

A circular gear with a diameter of 24 centimeters is mounted directly on another circular gear with a diameter of 96 centimeters. Both gears turn on the same axle at their exact centers and each gear has a single notch, at the 12 o'clock position. At the same moment, the gears begin to turn at the same rate, with the larger gear moving clockwise and the smaller gear counterclockwise. How far, in centimeters, will the notch on the larger gear have traveled the second time the notches pass each other?

(A) 32.2 pi
(B)35.6 pi
(C) 38.4 pi
(D) 39.2 pi
(E) 40.8 pi

C
Circumference of the larger gear = 96∏.
Circumference of the smaller gear = 24∏.

Let L = the notch on the LARGER gear and S = the notch on the SMALLER gear.

We can plug in the answers, which represent the distance traveled by L when the notches meet the SECOND TIME.
Since L and S travel at the SAME RATE, the answer choices also represent the distance traveled by S when the notches meet the second time.

Answer choice C: 38.4∏
Since 38.4∏cm are traveled the SECOND time L and S meet, the distance traveled by L and S the FIRST TIME they meet = (38.4∏)/2 = 19.2∏cm.

Of the larger gear's circumference, the portion traveled by L upon completing 19.2∏cm = 19.2∏ / 96∏ = 1/5.
Thus, L travels 1/5 of the CLOCKWISE distance.

Of the smaller gear's circumference, the portion traveled by S upon completing 19.2∏cm = 19.2∏ / 24∏ = 4/5.
Thus, S travels 4/5 of the COUNTERCLOCKWISE distance.

Success!
Since L travels 1/5 of the clockwise distance, and S travels 4/5 of the counterclockwise distance, the two notches MEET when each travels 19.2∏cm.

The correct answer is C.

Subject: Profile Evaluation - Average Grads + 3yrs of Work Ex
Posted: Mon Jun 24, 2013 11:50 am (GMT -7)

Hello
I would some feedback on my profile and some suggestions are areas I can improve. I plan to get into MBA in 2014, however I may postpone it to 2015 depending on some of the reasons I have mentioned ahead in the post.

Educational Status: Graduated in 2010
Degree: Bachelors in Computer Science - 61% (Aggregate) and 81% in final year.
Highlights:
- Multiple inter college competition winner during first two years of college.
- Final Year college project was sent to Department of Science and technology, Government of India. project was highly appreciated (I have letter from college Dean).

Work Experience:
- June 2010 to May 2012 as Marketing Executive for a startup(Dealt in Computer Hardware) By end of second year I was heading a team. During 2 years company's revenue grew 225%.
- May 2012 to Jan 2013 as Business Delivery Manager in an IT firm (fairly nascent, started in 2010). Managed over 50 projects - Websites, CRM, Application, Portals, Digital Marketing etc for companies in various sector like - Infrastructure, Education, Health, etc.
- Jan 2013 to present as CEO of an NGO I founded. At present I am working with Rural/Tribal Artisans. As of June 2013 I have reached out to over 10,000 people to empower them socially and economically. We inform them about government schemes and policies and how they can improve their business. To complement this we have started a service to create and host FREE website for various NGOs, Artisans. No charges, no hidden costs. Around 1000 of these artisans are from regions which are considered highly disturbed regions due to political and social unrest and high penetration of Naxals and terrorists.
Apart from this the NGO is also working on Education, Tourism and Heritage projects as well.

OTHER INFO:
- I have been working as freelance web developer since 2008. couple of my websites has raked in over 2 lakh posts and 25,000 Members.
- I am also the founder of Supporters Club of big Barclays Premier League Team.
- All the projects of my NGO has been conceived, implemented, marketed by me.
- I worked for another NGO in 2012 and was provided a medal for helping them organizing a National Tournament for Slum Kids.
- I was also involved with third NGO in Health Sector for 6 months in 2011.



Assuming my GMAT Score is 700, Kindly Evaluate my chances of Admission in Harvard, Stanford, Columbia, Wharton & London Business School. I had planned to get into MBA in 2014 but may delay it to 2015 and work on the NGO even more if itl boost my chances. There were 3 founding members and right now the volunteers number is touching 15 so even if I get into MBA, projects wont be affected. If you have any questions, do post here or Send me a Message.

Regards

I agree. For entertainment you would want to attend UCLA, USC, or NYU because of the Los Angeles and New York locations. Add Columbia in there as well for the same reasons.

Competitive means somewhere between target and stretch i.e. it is foreseeable you would be accepted to at least one of these school if you applied to say the group of them. Exact percentages are difficult to forecast but you should be assessing whether an application to these schools has a reasonable chance of success and in your case with your background, I feel it does.

Good luck,

I believe that the question stem is asking for the number of DERANGEMENTS.
A derangement is an arrangement in which NO ELEMENT is in the correct position.

I am new to this whole forum thing, but I would love to lay out a bit of my situation and see what you fine folks have to say. Currently, I am working full time as an account representative at an environmental service firm(a good job,) but have recently discovered (through a variety of situations/books/experiences) that my passion lies in a combination of finance, small business and non-profit consulting, and private equity management. Now, I am in the midst of studying for the GMAT and I see a big benefit to the knowledge I could obtain and connections I could make from going to a respected B-school (For me this would mean getting into Ross (as I live in Michigan) or possibly the online program from UNC...or any other suggested programs?) From what I have been reading, everyone seems to say that the full time programs produce more benefit for the student than those of a part-time MBA. Do most people agree with that sentiment? Secondly, is working full time in my current job a possiblity while doing a weekend/online MBA? And lastly, what do folks recommend about getting letters of recommendation when you are essentially saying to your employer, "I want you to endorse me to go to business school so I can pursue my passion in a different area."

If you have any insight on these inquiries I would love to get your feedback! Thanks!

Of the students in the class, 55% of the females and 35% of the males passed the exam. Did more than half the students pass the exam?

1) More than half the students in the class are females
2) The number of female students is 20 more than the the number of male students.
55% of the females passed the exam:
55/100 = 11/20.
Thus, 11/20 of the female students pass.
Implication:
The total number of female students must be a multiple of 20.

35% of the males passed the exam.
35/100 = 7/20.
Thus, 7/20 of the male students pass.
Implication:
The total number of male students must be a multiple of 20.

Statement 1: More than half the students in the class are females.

Try the LEAST POSSIBLE VALUES.
Case 1: Males = 20, Females = 40
Males who passed = 7/20 * 20 = 7.
Females who passed = 11/20 * 40 = 22.
Passed/total = (7+22)/(20+40) = 29/60.
Here, FEWER than half pass.

Try EXTREMES.
Case 2: Males = 20, Females = 80
Males who passed = 7/20 * 20 = 7.
Females who passed = 11/20 * 80 = 44.
Passed/total = (7+44)/(20+80) = 51/100.
Here, MORE than half pass.

Since FEWER than half pass in Case 1, but MORE than half pass in Case 2, INSUFFICIENT.

Statement 2: The number of female students is 20 more than the number of male students.

Try the LEAST POSSIBLE VALUES.
Case 1: Males = 20, Females = 40
Males who passed = 7/20 * 20 = 7.
Females who passed = 11/20 * 40 = 22.
Passed/total = (7+22)/(20+40) = 29/60.
Here, FEWER than half pass.

Try EXTREMES.
Case 3: Males = 100, Females = 120
Males who passed = 7/20 * 100 = 35.
Females who passed = 11/20 * 120 = 66.
Passed/total = (35+66)/(100+120) = 101/220.
Here, FEWER than half pass.

Case 3 illustrates that as the values INCREASE, the fraction who pass DECREASES.
Thus, the greatest possible fraction who pass = 29/60, which is LESS THAN 1/2.
SUFFICIENT.

The correct answer is B.
