GMAT Orange Percentage ProblemTerry has some oranges. Out of that, 4% were thrown away, 80% of the remaining oranges were sold and he is now left with 96 oranges. What was the initial number of oranges with him?

A) 100
B) 200
C) 300
D) 350
E) 400

Solution: This is a Percentages question. Let us take variable X as the total number of initial oranges with Terry.

Oranges thrown away: 4%*X

Remaining oranges: 96%*X

Oranges sold: 80%*96%*X

Total oranges left: 96 oranges

The equation for total number of oranges is therefore,

X – (4%*X + 80%*96%*X) = 96

=> X – (0.04X + 0.8*0.96*X) = 96
=> X - 0.77X = 96
=> 0.23X = 96
=> X = 300

Correct Answer: C

At a contest with 1,500 participants, 1/2 of the people are aged 8 to 12. Next year, the number of
people aged 8 to 12 will increase by 1/3. After this change, what percentage of the total 1,500 people will the 8 to 12 year olds represent?

A. 33%
B. 40%
C. 50%
D. 55%
E. 66.66%

Answer

Total Participants: 1500

This Year: Ages 8 to 12 - 750
Next Year: Ages 8 to 12 - 750 + 1/3 x 750 = 750 + 250 = 1000

Choice E: The new percentage is 1,000/1,500, or 2/3, which corresponds to 66 2/3%.

Two Common GMAT Percentage MistakesThe topic of percentages is one of the easiest that you will tackle on the GMAT. We are all accustomed to calculating percentages in our daily lives, and any potential question on this topic would seem to be a cakewalk to most. While that is generally true, there are also some traps and pitfalls that the GMAT will lay down for you. Be careful not to get caught in them! Here are some handy tips, tricks, and trap warnings to help you negotiate your way around GMAT questions on this topic:

Error Type 1: Using the wrong base when calculating percentage change

The percentage increase in a quantity when it is increased by a certain amount is [(new value – old value)/old value] x 100. Similarly the percentage decrease is [(old value-new value)/old value] x 100. This point seems to be fairly obvious. However, an exam situation can play tricks on anyone and cause them to make silly mistakes in a hurry.

A common error involves taking the new value in the denominator. If the price of a product increases from 120 to 140, the percentage increase is (20/120)*100 = 16.67%, not (20/140)*100...


Word OfOne of the smallest and least noteworthy words in the English language, the word “of” is crucial to your success on the GMAT, on both the quantitative and verbal sides of the exam. It is of great importance that you recognize these two common appearances of, and traps set by, the word “of“:

1) Sentence Correction

In Sentence Correction questions, the word “of” is usually employed as a modifier, which the GMAT often throws in to lengthen sentences and distract you from subject-verb agreement errors. Consider the following items:

The number of applicants to business schools are increasing given the current economic climate.

The House of Representatives are meeting this week to continue working on an environmental bill.

In each instance, the subject is actually the singular noun before the word “of” – “of applicants to business schools” just tells us “which number?”, and “of Representatives” simply indicates “which House?”. The authors of the GMAT know that examinees are often unsure of which noun to choose as the subject; by using the word “of” to set up modifiers with multiple nouns, the writers can exacerbate this problem.

Reviews

"I have not reviewed many books for MBA Admission consulting companies but doing it now to give all applicants a brief idea on what the book covers. The book includes 31 top MBA programs - almost all the top schools you have heard or considering for your MBA application. Each chapter is categorized by US States where there is at least one top MBA program. So you have California and Massachusetts with the most number of MBA programs and several states with one top program (Washington, Minnesota, Washington D.C., Connecticut, Virginia, and Maryland) and other states with two to three MBA programs. The book focuses on four aspects of an MBA program - curriculum, cost, class profile and post-MBA salary. For me, the breakdown of the cost and post-MBA industry was useful to make my decision on selecting the top 5 programs for 2017-18. It is a fascinating read in an industry where consultants overprice for their expertise. I recently bought a 30-page guide for $49. Compared to the obvious observation in that book, the 300+ page, MBA in US - the Ultimate guide is a goldmine of information and analysis." - Verified Purchase (21st June 2017)

"I bought the ultimate guide after a friend recommended it for me. The guide covers a lot of ground on the history of each prominent US states and goes into the reasons why a certain industry emerged from each state. In addition to the analysis of the economy, trends and expected changes in the next 5 years, the book features top MBA programs in each state with an extensive study of its curriculum. Ultimate guide is an essential reference book for MBA Applicants if they want to shortlist MBA programs based on value and cost, and not just ranking. " - Verified Purchase (14th June 2017)

"Should be a required reading before applying for an MBA. School events and MBA Tours are PR events disguised as a Q&A. On the contrary, the book is an unbiased analysis of each Top MBA program in the US supported by a large dataset and historical context on each industry. The guide builds a case for indstries that are likely to emerge as favourite for MBA graduates. Thorough and a valuable book." - Verified Purchase (15th June 2017)

"What I liked: The breadth of the information. Some of my favorite nonfiction books have taken the same approach as the ultimate guide have - cover background information in-depth. In the book, the author uses parallel threads to demonstrate the history of the state and the rise of industries. Will make you think how schools thrive based on the policy set by the state. California's obsession with Technology has revolutionized how we do Business and changed post-MBA trends. Many MBA applicants will be consulting or doing marketing for a Technology company. That is one key finding from the book. The latest development in AI, FinTech, and Automation is an additional context that I found valuable in the book.

Very informative. I would recommend that you read the book at least once in chronological order before using Table of Contents." - Verified Purchase (2nd July 2017)
