Question

The following figure represents for a company employing immigrants from different countries:

Which of the following is correct based on the given above chart?
A. America and China have same number of immigrants.
B. China and Africa have same number of immigrants.
C. America has twice the number of immigrants than China.
D. Africa has twice the number of immigrants than China.
E. America has twice the number of immigrants than India.
Choose the correct answer from the options given below:

• A. A, B and C Only
• B. A, C and D Only
• C. D and E Only
• D. B, C and D Only

Hint:

A quick glance at the bar lengths tells you that America's bar (50) is twice as long as India's bar (25), confirming E is true.
Also, Africa's bar (40) is twice as long as China's (20), confirming D is true.

Answer 1

The Correct Option is C

•

Step 1: Understanding the Question: This question is based on interpreting a horizontal bar chart that represents the numbers of immigrants from different countries.
We must read the exact numbers for each country and verify the comparative relationships.

•

Step 2: Key Formula or Approach:
First, identify the values for each country from the chart:
- China = 20
- India = 25
- Europe = 42
- America = 50
- Africa = 40
Next, evaluate each statement.

•

Step 3: Detailed Explanation:
Let us evaluate the statements:
- Statement A: "America and China have same number of immigrants."
America = 50, China = 20. They are not equal. (False)
- Statement B: "China and Africa have same number of immigrants."
China = 20, Africa = 40. They are not equal. (False)
- Statement C: "America has twice the number of immigrants than China."
America = 50, China = 20. Twice of China is \(2 \times 20 = 40\). This does not equal 50. (False)
- Statement D: "Africa has twice the number of immigrants than China."
Africa = 40, China = 20. Twice of China is \(2 \times 20 = 40\). This equals Africa's count. (True)
- Statement E: "America has twice the number of immigrants than India."
America = 50, India = 25. Twice of India is \(2 \times 25 = 50\). This equals America's count. (True)
Therefore, only statements D and E are true.

•

Step 4: Final Answer: Only statements D and E are correct, which corresponds to option (C).
