Yesterday, the whole wide internet was shocked by the Jeopardy dominance of “This dude Michael”, but here at Manhattan Prep we weren’t surprised at all. We already knew that dude was smart and we knew that dude had the mathematical wherewithal to bet $7,000 without batting an eyelash.
Here at MPrep we know that dude as Michael Bilow (one of those people who command such respect that he must always be talked about using his last name lest anyone in earshot mistakenly attribute an anecdote or joke to some less deserving Michael). On Jeopardy, he lived up to his legend taking home the fourth highest single-day winnings in Jeopardy history: $57,198.
Michael Bilow joined the Manhattan Prep family in 2011 using his perfect GRE score and spectacular teaching chops to secure a role as an LA-based GRE instructor. A few years later we realized we needed more Bilow in our business so we asked him to join the Marketing Department. He took a position as our Business Data Analyst, while continuing to teach GRE classes and pursue his PhD. After seeing him flawlessly juggle those responsibilities, we never had any doubt that he would take the Jeopardy world by fire.
By now the whole country knows of Bilow’s intellectual prowess, but we know so much more. Michael is a dedicated practitioner of improv, a delightful presence in Google Hangout meetings, and a stylish dresser. We can’t wait for his next trip to the New York City headquarters so he can buy us a drink with his winnings after he takes a quick a nap in a tutoring pod.
Congrats, Michael Bilow! Keep it up!

If you have two equations, you can solve for two variables.
This rule is a cornerstone of algebra. It’s how we solve for values when we’re given a relationship between two unknowns:
If I can buy 2 kumquats and 3 rutabagas for $16, and 3 kumquats and 1 rutabaga for $9, how much does 1 kumquat cost?
We set up two equations:
2k + 4r = 16
3k + r = 9
Then we can use either substitution or elimination to solve. (Try it out yourself; answer* below).
On the GMAT, you’ll be using the “2 equations à 2 variables” rule to solve for a lot of word problems like the one above, especially in Problem Solving. Be careful, though! On the GMAT this rule doesn’t always apply, especially in Data Sufficiency. Here are some sneaky exceptions to the rule…
2 Equations aren’t always 2 equations
Welcome to our third and final installment dedicated to those pesky maximize / minimize quant problems. If you haven’t yet reviewed the earlier installments, start with part 1 and work your way back up to this post.
I’d originally intended to do just a two-part series, but I found another GMATPrep® problem (from the free tests) covering this topic, so here you go:
“A set of 15 different integers has a median of 25 and a range of 25. What is the greatest possible integer that could be in this set?
Here’s the general process for answering quant questions—a process designed to make sure that you understand what’s going on and come up with the best plan before you dive in and solve:
Fifteen integers…that’s a little annoying because I don’t literally want to draw 15 blanks for 15 numbers. How can I shortcut this while still making sure that I’m not missing anything or causing myself to make a careless mistake?
Hmm. I could just work backwards: start from the answers and see what works. In this case, I’d want to start with answer (E), 50, since the problem asks for the greatest possible integer.
We’re going to kill two birds with one stone in this week’s article.
Inference questions pop up on both Critical Reasoning (CR) and Reading Comprehension (RC), so you definitely want to master these. Good news: the kind of thinking the test-writers want is the same for both question types. Learn how to do Inference questions on one type and you’ll know what you need to do for the other!
That’s actually only one bird. Here’s the second: both CR and RC can give you science-based text, and that science-y text can get pretty confusing. How can you avoid getting sucked into the technical detail, yet still be able to answer the question asked? Read on.
Try this GMATPrep® CR problem out (it’s from the free practice tests) and then we’ll talk about it. Give yourself about 2 minutes (though it’s okay to stretch to 2.5 minutes on a CR as long as you are making progress.)
“Increases in the level of high-density lipoprotein (HDL) in the human bloodstream lower bloodstream cholesterol levels by increasing the body’s capacity to rid itself of excess cholesterol. Levels of HDL in the bloodstream of some individuals are significantly increased by a program of regular exercise and weight reduction.
“Which of the following can be correctly inferred from the statements above?
“(A) Individuals who are underweight do not run any risk of developing high levels of cholesterol in the bloodstream.
“(B) Individuals who do not exercise regularly have a high risk of developing high levels of cholesterol in the bloodstream late in life.
“(C) Exercise and weight reduction are the most effective methods of lowering bloodstream cholesterol levels in humans.
“(D) A program of regular exercise and weight reduction lowers cholesterol levels in the bloodstream of some individuals.
“(E) Only regular exercise is necessary to decrease cholesterol levels in the bloodstream of individuals of average weight.”
Got an answer? (If not, pick one anyway. Pretend it’s the real test and just make a guess.) Before we dive into the solution, let’s talk a little bit about what Inference questions are asking us to do.
Inference questions are sometimes also called Draw a Conclusion questions. I don’t like that title, though, because it can be misleading. Think about a typical CR argument: they usually include a conclusion that is…well…not a solid conclusion. There are holes in the argument, and then they ask you to Strengthen it or Weaken it or something like that.
Last time, we discussed two GMATPrep® problems that simultaneously tested statistics and the concept of maximizing or minimizing a value. The GMAT could ask you to maximize or minimize just about anything, so the latter skill crosses many topics. Learn how to handle the nuances on these statistics problems and you’ll learn how to handle any max/min problem they might throw at you.
Feel comfortable with the two problems from the first part of this article? Then let’s kick it up a notch! The problem below was written by us (Manhattan Prep) and it’s complicated—possibly harder than anything you’ll see on the real GMAT. This problem, then, is for those who are looking for a really high quant score—or who subscribe to the philosophy that mastery includes trying stuff that’s harder than what you might see on the real test, so that you’re ready for anything.
Ready? Here you go:
“Both the average (arithmetic mean) and the median of a set of 7 numbers equal 20. If the smallest number in the set is 5 less than half the largest number, what is the largest possible number in the set?
Out of the letters A through E, which one is your favorite?
You may be thinking, “Huh? What a weird question. I don’t have a favorite.”
I don’t have one in the real world either, but I do for the GMAT, and you should, too. When you get stuck, you’re going to need to be able to let go, guess, and move on. If you haven’t been able to narrow down the answers at all, then you’ll have to make a random guess—in which case, you want to have your favorite letter ready to go.
If you have to think about what your favorite letter is, then you don’t have one yet. Pick it right now.
I’m serious. I’m not going to continue until you pick your favorite letter. Got it?
From now on, when you realize that you’re lost and you need to let go, pick your favorite letter immediately and move on. Don’t even think about it.
The Graduate Management Admission Test, better known as the GMAT®, is a standardized test used in the admissions process for business school and other specialized Master’s programs. The exam measures certain skills that the business schools care about, most notably Executive Reasoning skills. It does not test any specific business knowledge.
When is the GMAT given?
You can take the GMAT year-round, nearly any day of the week (though they limit you to 5 sittings in a 12-month period and require a wait of 31 days between tests). The exam is given on a computer and is known as a “CAT.”
What is a CAT?
A CAT is a computer-adaptive test: the test actually adapts itself to you while you’re taking it! Two of the four sections on the GMAT, the Quantitative and Verbal sections, are adaptive. Each of these two sections begins with a random, approximately medium-level question. The computer chooses each subsequent question based upon your collective performance to that point in the section.
The practical implications are important. First, every test taker will take a different exam with a different mix of questions, but the test feels hard for everyone, since the test will just keep getting harder until it finds a particular person’s limit. Second, the scoring is pretty peculiar; it’s important to understand how the scoring works.

How is the GMAT Scored?
Tests you took in school were generally based on the percentage of questions answered correctly: the more you got right, the higher the score you received. As a result, you have been trained to take your time and try to get everything right when you take a test. This general strategy does not work on computer-adaptive sections of the GMAT because, strangely enough, the quant and verbal scores are not based on the percentage of questions answered correctly. On the GMAT, most people answer similar percentages of questions correctly, typically in the 50% to 70% range (even at higher scoring levels!).
How is that possible? The first thing to know: the GMAT is not a school test. The quant section is not really a math test, and the verbal section is not really a grammar test. Of course, you do need to know how to handle those topics. The test writers are really interested, however, in knowing how good you are at making decisions and managing scarce resources. (That’s the second time we’ve linked to that same article. Go read it!)
