The following table shows the number of males (M) and females (F) (in thousands) in Towns X and Y during the five years from 2018 to 2022. Based on the data in the table, answer the questions 1-5

Year wise numbers of Males and Females in two Towns (in thousands)

Table X			Table Y
Year	Number of Males	Number of Females	Number of Males	Number of Females
2018	50	49	53	53
2019	52	49	54	52
2020	55	52	55	54
2021	53	53	58	56
2022	55	52	62	55

The population of Town X in 2018 and 2019 together approximately __________% of the population of Town Y in 2021 and 2022 together?

The correct answer is 86.6%.

To solve this, we need to find the total population of Town X in 2018 and 2019 combined, then express it as a percentage of the total population of Town Y in 2021 and 2022 combined.

Step 1: Calculate the total population of Town X in 2018 and 2019.

From the table, the data for Town X is:

- 2018: Males = 50 (thousands), Females = 49 (thousands) ⇒ Total = 50 + 49 = 99 thousand
- 2019: Males = 52 (thousands), Females = 49 (thousands) ⇒ Total = 52 + 49 = 101 thousand

Combined population of Town X (2018 + 2019):

$99+101=200\text{thousand}$

Step 2: Calculate the total population of Town Y in 2021 and 2022.

From the table, the data for Town Y is:

- 2021: Males = 58 (thousands), Females = 56 (thousands) ⇒ Total = 58 + 56 = 114 thousand
- 2022: Males = 62 (thousands), Females = 55 (thousands) ⇒ Total = 62 + 55 = 117 thousand

Combined population of Town Y (2021 + 2022):

$114+117=231\text{thousand}$

Step 3: Express Town X's combined population as a percentage of Town Y's combined population.

$\text{Percentage}=\frac{\text{Population of Town X (2018 + 2019)}}{\text{Population of Town Y (2021 + 2022)}}\times 100$

$\text{Percentage}=\frac{200}{231}\times 100$

$\text{Percentage}=0.8658\times 100=86.58\%$

Step 4: Round to one decimal place.

$86.58\%\approx 86.6\%$

Therefore, the population of Town X in 2018 and 2019 together is approximately 86.6% of the population of Town Y in 2021 and 2022 together.
