i asked Dr Math at http://mathforum.org/dr.math/faq/faq.divisibility.html and he gave me the ans..hi hi...i post to evrybody If the price for the balcony seats is $10, then all 100 seats will be sold. As the price for the balcony seats increases, fewer people will buy tickets because of the higher prices.
In fact, we are told that each time the price increases by $2, the number of people buying tickets will decrease by 5. So if the price goes up from $10 to $12, then the number of people buying tickets will go down from 100 to 95. Then when the price goes up again from $12 to $14, the number of people buying tickets will decrease from 95 to 90. And so on.
We need to find which combination of ticket price and number of tickets sold gives $1360 as the total amount of ticket sales:
price number total sales --------------------------- 10 100 1000 12 95 1140 14 90 ?? 16 85 ?? 18 80 ?? ... and we got the ans....:) |

hey everyone! i recently started studying for the GMAT and i'm confused by this question. does anyone know how to solve it?? I tried but can't figure out the venn diagram. I'd love a detailed explanation on how you get the answer :) thanks.
1. Of 200 students taking the GMAT, all of them have college degrees, 120 have been out of college for at least 3 years, 70 have business degrees, and 60 have been out of college for less than 3 years and do not have business degrees. How many of them have been out of college for at least 3 years and have business degrees.
(A) 40 (B) 50 (C) 60 (D) 70 (E) 80 |

Venn diagrams are awesome, but they aren't always the best solution to set problems.

Solution: Because the categories into which the students have been divided are mutually exclusive, we use a table, and not a Venn diagram:

Note that you don’t have to fill out the entire table to obtain the correct answer which is (B)
Just as a reminder - only use a Venn diagram when your categories overlap; for categories that are mutually exclusive, use a table
