If 15% of the 500 workers are women that means that there are 75 women in the first group. if you add 50 workers then you have a total of 550 workers and you want 20% of them to be women. 20% of 550 is 110 so you need 110 women. if you have 75 women originally then you need to add 35 women to get to...

To get the area of the big circle we need the value for R. Statement 1 doesn't contain any values so it will not be sufficient. BCE are left statement 2 tells us that 75 = (R-r)(R+r) - which means that 75 = R^2 - r^2 but we don't have any relationship between R and r so we can't figure out what the ...

Deciding between the GRE and the GMAT is a decision with many variables - the GRE is now a very different test from the GMAT - both tests use the same math information but there is no Data sufficiency on the GRE and the GRE has a section called the Quant comp which is similar but different. Also the...

Many students face this issue. The best way to deal with it is to remember that studying is a balance between technique, specifics and the big picture. You need to maintain a vision of all three things at least weekly. meaning you need to review and work on each of the things at least one time per w...

You are looking to strengthen - so you need another fact that makes it more likely that the law should not be enacted. A) - repeats info we already know. B) - knitting needles shouldn't be banned and the fact that hypodermic needles' benefits outweigh those of knitting needles doesn't make it more t...

There are lots of issues involved in any verbal score - the ability to read and comprehend, the knowledge of question types and the ability to pick apart the answers to match the words in correct answers to the passages. In SC I recommend that you focus on the six big errors tested on this exam - kn...

you have to do the numbers inside the square root before you can take the square root so x^2 + y^2 = 25 then you do square roots before addition so 3 + 5 is on the numerator (only the positive root becuase of the sqrt sign). You can't do the fraction first because there is addtion in the numerator s...

It says the first but when you put in the a and b it is just about first number, second number so the equation says 2(first nubmer) - second number.

It may help here to find the equivalent angles and write them down - a=d=e=h and c=b=g=f then write the equation from the question in two variables (using the equivalences) a+f+a-(a+a) = 2a +f - 2a = f so you are really only looking to solve for the value of f. but with parallel lines you know that ...

you can rewrite the question 2a-b>2b-a you can manipulate that to 3a>3b and divide both sides by three to get the real question to be is a>b? Statement 1 says that a is in fact less than b therefore a can never be greater than b which means this is a sufficient answer because we can always answer th...

The trick of this problem is recognizing that you need to do two things - percent and then probability. The probability part will be easy if you know the percent because you can figure out how many candidates are left and the probability of not being the one picked. Statement 1 tells you the percent...

In order to answer this question you need to recognize that you cannot find the mean of the original problem without X - the mean will be (26 + Z)/6 ane the percent change will be [n(26+z)/6 - (26+Z)/6]/(26+z)/6 - thus you need both Z and N to solve the problem 1) give you Z but not n 2)N = Z/M give...
