Average (arithmetic mean): GRE / GMAT Math

A quick video covering my favourite trick for averages, a topic that comes up all the time on the GRE and the GMAT. You know the formula for average: sum of terms divided by number of terms, but I think of it a different way...

The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.

Hi Philip, at first thank you for your efforts (you are the best). For the community could be very helpful if you explain how to attack the totally underlined sentence corrections. Wish you the best, have a nice day!

[CryptoNerd]

Nice videos Phil. Would like to see some videos related to exercise and your day to day routines. The insight can be highly beneficial. Good man!!

[bradleygoronson]

So obvious and so useful! Thanks for all the videos, Phillip!

Thanks for the tips. However, in question 1, the wordings are not clear. The average was 500 in the first 3 tests (so the total is 1500). In the 4th test, the average increased to 550. But when you multiply 550 by 4, it means she attempted 4 new attempts!

Please upload some video related how to improve reading comprehension skills and which resources are good for practicing improving reading skill. I am very slow in comprehending passage. Please share your thoughts 🙏

[esraamansour]

the last problem is so tricky for me 😅

[shafiabdullahhauque]

Loved the trick, but couldn't understand what you did in the last problem after the equation x+y= 93. Please clarify. Thanks.

[Abhishek-fezs]

For the last question, say x equals 40, then y would equal 53. Since both x and y are variables, why can't we assign 40 and 53? If we do it this way, then a, b, c, d and e are all correct.

34. Four students contributed to a charity drive, and the average (arithmetic mean) amount
contributed by each student was $20. If no student gave more than $25, what is the
minimum amount that any student could have contributed?

Greetings!
Your videos are very helpful.
I am currently preparing for the GMAT. I've come across a question involving the arithmetic mean similar to what you just explained. However, it is harder and more confusing. Would it be possible to ask for your approach or insight about it?
Thank you!

[poojapatel]

why isn't F, 77 correct? X would be less than Y, and the average equals 37. Do you mind elaborating on this one please?

[aliacooperfrazier]

Can you do a video on how to do logarithms please?

[kjsohklm]

Thank you ver much! It’s so helpful. Please do more video
May Allah bless you so much!
