B. The population of Manila is greater than the population of New York.
C. New York has a smaller land area than Delhi or Manila.
D. New York has a larger land area than Delhi or Manila.



Answer :

To solve the problem, let's go through the calculations and conclusions step-by-step:

1. Determine the land areas of each city:

- Delhi (India):
[tex]\[ \text{Area of Delhi} = \frac{\text{Population of Delhi}}{\text{Pop. Density of Delhi}} = \frac{22,826,000}{30,400} \approx 750.86 \quad \text{sq mi} \][/tex]

- Manila (Philippines):
[tex]\[ \text{Area of Manila} = \frac{\text{Population of Manila}}{\text{Pop. Density of Manila}} = \frac{21,241,000}{38,300} \approx 554.60 \quad \text{sq mi} \][/tex]

- Karachi (Pakistan):
[tex]\[ \text{Area of Karachi} = \frac{\text{Population of Karachi}}{\text{Pop. Density of Karachi}} = \frac{20,877,000}{67,300} \approx 310.21 \quad \text{sq mi} \][/tex]

- New York (US):
[tex]\[ \text{Area of New York} = \frac{\text{Population of New York}}{\text{Pop. Density of New York}} = \frac{20,673,000}{4,600} \approx 4494.13 \quad \text{sq mi} \][/tex]

2. Analyze the conclusions based on the calculated areas:

- Conclusion 1:

"The land areas of Karachi and New York must be very similar in size."

- Karachi: [tex]\( 310.21 \ \text{sq mi} \)[/tex]
- New York: [tex]\( 4494.13 \ \text{sq mi} \)[/tex]

These areas are not similar in size. So, this conclusion is false.

- Conclusion 2:

"The population of Manila is greater than the population of New York."

- Manila: [tex]\( 21,241,000 \)[/tex]
- New York: [tex]\( 20,673,000 \)[/tex]

Manila's population is indeed greater than New York's. So, this conclusion is true.

- Conclusion 3:

"New York has a smaller land area than Delhi or Manila."

- New York: [tex]\( 4494.13 \ \text{sq mi} \)[/tex]
- Delhi: [tex]\( 750.86 \ \text{sq mi} \)[/tex]
- Manila: [tex]\( 554.60 \ \text{sq mi} \)[/tex]

New York has a larger land area compared to both Delhi and Manila. So, this conclusion is false.

- Conclusion 4:

"New York has a larger land area than Delhi or Manila."

- New York: [tex]\( 4494.13 \ \text{sq mi} \)[/tex]
- Delhi: [tex]\( 750.86 \ \text{sq mi} \)[/tex]
- Manila: [tex]\( 554.60 \ \text{sq mi} \)[/tex]

New York indeed has a larger land area compared to both Delhi and Manila. So, this conclusion is true.

Therefore, based on the calculations:

- The correct conclusions from the table are:
1. The population of Manila is greater than the population of New York.
2. New York has a larger land area than Delhi or Manila.
