Hi there! I would add to the previous post by saying that another way to strengthen a plan is to remove a possible weakness. It's addition by subtraction! You're strengthening the plan by eliminating a potential problem with the plan. So in this case, we see an answer written in the negative (e.g. X...

Hi! The absolute simplest way to solve this problem is to realize that the two statements are talking about the SAME people. That is, the people who are in both groups. So while I think it's fairly clear that neither statement individually will allow you to answer the question (but if not, other exp...

I thought this essay was very good, at least worth a 5 and quite possibly a 6. You perfectly described the disconnect between premises and conclusion. You include info that would strengthen the argument. Your writing style is very good, aside from a colloquialism or two ("a stretch" may be...

Here's why Statement 2 is not sufficient: You can prove that it's insufficient by using real numbers to arrive at two different answers. In this case, Statement 2 tells you that the area, (1/2)(base)(height)= 4.5. So that means that (base)(height) = 9 Well, the base and the height could be 3 and 3, ...

Another way to think about this kind of problem (without doing algebra) is to plug in a number of "widgets" to represent the entire job. Since we're working with 4, 5, and 6, let's make the job equal to 120 widgets (a nice multiple of 4, 5, and 6). Job = 120 Widgets. Now, you're told that ...

I'd definitely be using the answers here. In general, when I'm testing out the answers, I start with the middle choice, answer C. What if Bob got $24? That's $4 plus 1/3 of what remains, so 1/3 of what remains would have to be $20 and therefore what was remaining at that point would be $60. Now, we ...

An easy way to find the sum of consecutive numbers is to recognize that, in a list of consecutive numbers, the average is equal to the median. So all you have to do is find the median and multiply that by the number of numbers to get the sum. So for this problem, first figure out the number of numbe...
