Given Information:
In 2020, the ratio of the population of villages A, B, and C is 2:4:7.
Increment in Population:
In 2021, the population of each village increases as follows:
- Village A: 100% increment
- Village B: 50% increment
- Village C: 14.29% increment
Calculating the Population Ratio in 2021:
To find the ratio of the population in 2021, we need to calculate the population of each village after the increments.
Let's assume the initial population of villages A, B, and C in 2020 to be 2x, 4x, and 7x respectively.
After the increments in 2021:
- Population of village A = 2x + 100% of 2x = 2x + 2x = 4x
- Population of village B = 4x + 50% of 4x = 4x + 2x = 6x
- Population of village C = 7x + 14.29% of 7x = 7x + (14.29/100) * 7x = 7x + x = 8x
Therefore, the population ratio of villages A, B, and C in 2021 is 4x : 6x : 8x.
Simplifying the Ratio:
To simplify the ratio, we can divide each term by the common factor, which is 2x.
- Population of village A = 4x ÷ 2x = 2
- Population of village B = 6x ÷ 2x = 3
- Population of village C = 8x ÷ 2x = 4
Therefore, the simplified population ratio of villages A, B, and C in 2021 is 2:3:4.
Conclusion:
The ratio of the population of villages A, B, and C in 2021 is 2:3:4. Thus, option A is the correct answer.
In 2020, the ratio of the population of villages A, B, and C is 2:4:7.
Increment in Population:
In 2021, the population of each village increases as follows:
- Village A: 100% increment
- Village B: 50% increment
- Village C: 14.29% increment
Calculating the Population Ratio in 2021:
To find the ratio of the population in 2021, we need to calculate the population of each village after the increments.
Let's assume the initial population of villages A, B, and C in 2020 to be 2x, 4x, and 7x respectively.
After the increments in 2021:
- Population of village A = 2x + 100% of 2x = 2x + 2x = 4x
- Population of village B = 4x + 50% of 4x = 4x + 2x = 6x
- Population of village C = 7x + 14.29% of 7x = 7x + (14.29/100) * 7x = 7x + x = 8x
Therefore, the population ratio of villages A, B, and C in 2021 is 4x : 6x : 8x.
Simplifying the Ratio:
To simplify the ratio, we can divide each term by the common factor, which is 2x.
- Population of village A = 4x ÷ 2x = 2
- Population of village B = 6x ÷ 2x = 3
- Population of village C = 8x ÷ 2x = 4
Therefore, the simplified population ratio of villages A, B, and C in 2021 is 2:3:4.
Conclusion:
The ratio of the population of villages A, B, and C in 2021 is 2:3:4. Thus, option A is the correct answer.
