This is an LSAT question of a type that has no equivalent on the GMAT test. How do we find the conclusion of arguments? There are many ways, but here are some ideas: 1. Look to the question. Many times the conclusion is contained in the question or the question will give you a hint (e.g., the scient...

With questions such as these, it is best to start by asking ourselves this important question: What do I need? We need to know whether x is even, so if we knew that x is an even number times some other number that would be enough information. Similarly, if we knew that x was a multiple of two odd nu...

With questions such as these, it is best to read the question stem first. Our goal is to find a necessary assumption for this question. The conclusion is: The athletes would be better off consuming regular Cheetah Swift. Why? Because Cheetah Swift zero contains chemicals known to cause a harmful eff...

As we already know (C) is the best answer. You have asked about (E). Could this be the right answer? No, because the argument states: This meeting allows scientists to gather previously unobtainable data about the communication abilities of both of these species, which normally would not come into c...

It is best to start off with questions such as these by asking ourselves: What do we need? Generally speaking, we would need to know values for both x and y. However, if either x or y were 0 that would be sufficient on its own. Similarly, if x were 1, that would also be sufficient. So perhaps a narr...

This is a simple counting problem and, like most of these types of problems on the GMAT, it is designed to be a time waster. There are several possible solutions to this problem. The first thing we could do is skip it entirely. If we choose to do so, we should pick either option B or D, because thes...

The best way to handle inference questions such as this one is to start by reading the question stem. This lets us know what task we have to accomplish with the stimulus text. We should not read the text until we know what our task is. Once we have read and understood the task, most people will alre...

Probably the easiest way to solve these types of problems is to run scenarios.
Let x, which must be odd, = 1
Let y, which must be even, = 2
(A) 3(1)+2/1 = 3+1 = 4
So (A) could be even. That's your answer. No need to test further.

Solution
It's not necessary to do a lot of complicated math if you simply realize that for it to come out as an integer, x+y will probably need to be 5. If x+y = 3, 4, 6 or 7, you're not going to get integers out. 8 might work if x=2 and y=6, but we'll deal with that after checking 5. Since x is less than y ...

Another LSAT question -- you seem to love them. Have you ever considered asking GMAT questions in the GMAT forum? Just curious. What's the conclusion of the argument? It is: The concern about [the medication's] side effects is unfounded. Why? Because harmful side effects can be averted PROVIDED pati...

The problem can be simplified by considering A as stationary, B as 2 m/s (the difference between the speed of B and A) and C as 6 m/s (9 m/s - 3 m/s). Accordingly, it will take B at least 30 seconds to get completely around the track and catch up with A. C, on the other hand, will have moved 6*30 = ...

If you're doing a lot of math, chances are you're doing something wrong. The Quant part of the GMAT isn't a math test -- it's a test of reasoning ability. If you travel half of the trip at 24 mph and the other half at 48 mph, then you will average 36 mph. However, John only did 12 miles of 60 miles ...

I think you meant to ask:
The integers m and p are such that 2 is less than m and m is less than p. Also, m is not a factor of p.
If r is the remainder when p is divided by m, is r > 1?
1. The greatest common factor of m and p is 2.
2. The least common multiple of m and p is 30.

You have asked why (E) isn't the best option. In the argument we find that "... there was no reduction in the number of people suntanning on the beach each day." So although (E) suggests that the percentage of people outdoors reduced, that does not mean that the absolute number of people d...

When we do a data sufficiency question, it is best to start by asking ourselves: "What do we need?" In this case, we need to know what xy is. So we either need an equation or a system of equations that provides us with one single value for both x and y or that lets us eliminate parts and c...
