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...

These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.

    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?

    You follow the trick I showed, so multiply the average to get a total of $80. We want minimum for 1 student so we maximise the others, that's 3 x max of 25 = 75. Leaving $5 for the minimum. :)

    Since it says "could be" why is the answer not C, D or E? It doesn't seem to ask for the absolute highest value it could be but rather of the choices which are possible scenarios? And C, D, and E all seem to fit?

    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!
