7/9 of the people present in a hall are sitting in 9/13 of the chairs ...
Understanding the Problem
Given:
- 7/9 of people are sitting in 9/13 of the chairs available
- The remaining people are standing
- There are 28 empty chairs
To find:
- Number of chairs that would have been still empty if everyone was sitting

Solution

Step 1: Find the total number of people in the hall
Let the total number of people in the hall be represented by P.
Since 7/9 of the people are sitting, the number of people sitting = 7/9 * P
Since the remaining people are standing, the number of people standing = 2/9 * P

Step 2: Find the total number of chairs in the hall
Let the total number of chairs in the hall be represented by C.
Since 9/13 of the chairs are occupied, the number of occupied chairs = 9/13 * C
Since 28 chairs are empty, the number of empty chairs = 28
Therefore, the number of chairs occupied = C - 28

Step 3: Find the number of chairs each person occupies
Let the number of chairs each person occupies be represented by N.
N = (C - 28) / (7/9 * P)

Step 4: Find the total number of chairs if everyone is sitting
Total number of chairs when all people are sitting = P * N

Step 5: Calculate the number of chairs that would have been still empty
Number of chairs that would have been still empty = Total number of chairs when all people are sitting - (C - 28)
By calculating the above steps, we can determine the number of chairs that would have been still empty if everyone in the hall was sitting.

Passage 2After the end of World War II, a pervasive, but unfortunately fallacious, economic perspective took hold. Based on the United States successful emergence from the Depression, the idea that war was good for an economy became fashionable. However, linking the United States economic recovery with its entry into World War II is a prime example offlawed economic thinking.Supporters of the war benefits economy theory hold that a country at war is a country with a booming economy. Industry must produce weapons, supplies, food, and clothing for the troops. The increased production necessitates the hiring of more people, reducing unemployment. More employment means more money in the pockets of citizens, who are then likely to go out and spend that money, helping the retail sector of the economy. Retail shops experience an increase in business and may need to hire more workers, further reducing unemployment and adding to the economic momentum. While this scenario sounds good in theory, it does not accurately represent what truly happens in a war time economy.In reality, the government can fund a war in a combination of three ways. It can raise taxes, cut spending on other areas, or increase the national debt. Each of these strategies has a negative impact on the economy. An increase in taxes takes money out of an individuals hands, leading to a reduction in consumer spending.Clearly, there is no net benefit to the economy in that case. Cutting spending in other areas has its costs as well, even if they are not as obvious.Any reduction in government spending means the imposition of a greater burden on the benefactors of that government spending. Cutbacks in a particular program mean that the people who normally depend on that program now must spend more of their money to make up for the government cuts. This also takes money out of consumers hands and leaves the economy depressed. Of course, a government could go into debt during the war, but such a strategy simply means that at some point in the future, taxes must be increased or spending decreased. Plus, the interest on the debt must be paid as well.Q. Which of the following situations best mirrors the effect that cutting spending in government programs has, as detailed in the passage?
