### Manipulating Inequalities and Absolute Values on the GRE

Most people dislike absolute value, and inequalities can tie us up into knots. Put them together, and we can have some major headaches! Let’s test one out.

* |x “ 2| > 3

Quantity A                                                                 Quantity B

The minimum possible                                              The minimum possible

value of |x “ 3.5|                                                        |x “ 1.5|

What did you get? (Do you remember the 4 QC answer choices? I didn’t list them above! If you don’t know what they are, go look them up. I’ll wait. And the pain of having to look them up will help convince you that you need to memorize these.)

We have a given:

|x “ 2| > 3

So, first, let’s figure out what this actually means. For what values of x is this inequality true?

### Using Smart Numbers to Avoid Algebra on the GRE

Many word problems seem to require us to write formulas in order to solve. Certain problems, though, qualify for a neat technique: Smart Numbers. We can actually pick our own real numbers and use them to solve!

Set your timer for 2 minutes for this Fill-In problem and GO! (© ManhattanPrep)

* Lisa spends 3/8 of her monthly paycheck on rent and 5/12 on food. Her roommate, Carrie, who earns twice as much as Lisa, spends ¼ of her monthly paycheck on rent and ½ on food. If the two women decide to donate the remainder of their money to charity each month, what fraction of their combined monthly income will they donate? (Assume all income in question is after taxes.)

(No answer choices given; this is a fill-in-the-blank)

We’ve got two women, Lisa and Carrie, and they each spend a certain proportion of income on rent and on food. Annoyingly, the fractions don’t have the same denominators; even more annoyingly, the two women don’t make the same amount of money. All of that will make an algebraic solution challenging.

Here’s what an algebraic solution would look like. Let’s call Lisa’s income x. She spends (3/8)x on rent and (5/12)x on food. Add these together:

(3x/8) + (5x/12) = (9x/24) + (10x/24) = 19x/24

Subtract from 100%, or x:

24x/24 “ 19x/24 = 5x/24

Lisa donates 5/24 of x, her income, to charity. What about Carrie?

Carrie’s income is equal to 2x (because she makes twice as much as Lisa). How much does she spend on rent and food?
