Question

What was the total numbers of males and females in year 2016 in all countries together?

• A. 53200
• B. 51200
• C. 54800
• D. 55000

Hint:

To simplify addition, sum all males first, then all females, and add the two totals:
- Total Males $= 4.2 + 5.4 + 6.2 + 8.5 + 7.6 = 9$
- Total Females $= 3.2 + 3.2 + 3.3 + 7.9 + 5.5 = 1$
- Combined $= 9 + 1 = 55.0\text{ thousand} = 55000$.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
To find the total population of all countries in a specific year, we sum both the male and female populations across all five countries (A, B, C, D, and E).

Step 2: Detailed Explanation:
Let us extract the population values for the year 2016 (in thousands) for all countries:
- Country A:
\[ \text{Male} = 4.2, \quad \text{Female} = 3.2 \implies \text{Total} = 4.2 + 3.2 = 7.4 \]
- Country B:
\[ \text{Male} = 5.4, \quad \text{Female} = 3.2 \implies \text{Total} = 5.4 + 3.2 = 8.6 \]
- Country C:
\[ \text{Male} = 6.2, \quad \text{Female} = 3.3 \implies \text{Total} = 6.2 + 3.3 = 9.5 \]
- Country D:
\[ \text{Male} = 8.5, \quad \text{Female} = 7.9 \implies \text{Total} = 8.5 + 7.9 = 16.4 \]
- Country E:
\[ \text{Male} = 7.6, \quad \text{Female} = 5.5 \implies \text{Total} = 7.6 + 5.5 = 13.1 \]
Now, calculate the sum of these totals:
\[ \text{Grand Total} = 7.4 + 8.6 + 9.5 + 16.4 + 13.1 \]
\[ \text{Grand Total} = 55.0 \text{ thousand} \]
Since the values in the table are in thousands, we multiply by 1000 to find the actual population:
\[ \text{Actual Total Population} = 55.0 \times 1000 = 55000 \]
This matches Option D.

Step 3: Final Answer:
The total population across all countries in 2016 is 55000.
