The integers that go into the gray region are those that do not fall into any of the three sets 
, 
, or 
. We can eliminate the integers by taking the universal set and eliminating the elements that fall in any one of the three.
Out of the 50 integers from 1 to 50, we can eliminate the 20 that are in

Flight 783 departs from Oslo, Norway when it is 7:12 AM there; it lands in Dallas when it is 10:37 AM there. How long did the flight take?
(Assume Daylight Savings Time is not in effect.)
Refer to the time zone differences printed at the top of the map. The time zone for Dallas is marked 
; the time zone for all of Norway is marked 
. This means that Oslo is 
hours ahead of Dallas, so we need to adjust accordingly.

Three candidates - Craig, Donna, and Elly - ran for student body president. By the rules, the candidate who wins more than half the ballots cast wins the election outright; if no candidate wins more than half, there must be a runoff between the two top vote-getters. You may assume that no other names were written in.
As can be seen in the figure above, which reflects the share of the vote each candidate won, there will be a runoff. Which two candidates will face each other?
Statement 1: Candidate C is Donna.
Statement 2: Craig won 528 votes.

Statement 1: Candidate C is Donna.
Statement 2: Craig won 528 votes.
From Statement 1 alone, it can be seen that Donna's share of the vote was the smallest of the three. Therefore, Craig and Elly were the top two votegetters, and they will face each other in the runoff.
Statement 2 alone provides insufficient information; without knowing the total number of voters, the share of the vote won by Craig (or any other candidate) cannot be determined from the number of votes Craig won.

Refer to the diagram. If 3,145 people voted in the school board election, (the results of which are represented in the diagram), then approximately how many people voted for Inman?
According to the legend, the gray sector represents the portion of the electorate who voted for Inman. This sector is about one-fifth of the circle, so, to find the best estimate of Inman's share of the vote, take one-fifth of 3,145 - or, equivalently, divide 3,145 by 5:
630 is the best estimate of the choices given.
