Correct option is A
440
Calculate the total number of boys in School A from 2016 to 2020:
- 2016: 4.2 (hundreds) = 420
- 2017: 7.7 (hundreds) = 770
- 2018: 10.4 (hundreds) = 1040
- 2019: 6.5 (hundreds) = 650
- 2020: 9.5 (hundreds) = 950
Total boys in School A = 420 + 770 + 1040 + 650 + 950 = 3830
2. Calculate the total number of boys in School B from 2016 to 2020:
- 2016: 4.7 (hundreds) = 470
- 2017: 5.3 (hundreds) = 530
- 2018: 7.9 (hundreds) = 790
- 2019: 10.7 (hundreds) = 1070
- 2020: 11.9 (hundreds) = 1190
Total boys in School B = 470 + 530 + 790 + 1070 + 1190 = 4050
3. Find the difference between the number of boys in School A and School B:
Difference = Total boys in School B - Total boys in School ADifference = 4050 - 3830 = 220
However, the answer options are given in hundreds.
Let's check the calculations again.
- School A: 4.2 + 7.7 + 10.4 + 6.5 + 9.5 = 38.3 (hundreds) = 3830
- School B: 4.7 + 5.3 + 7.9 + 10.7 + 11.9 = 40.5 (hundreds) = 4050
Difference: 40.5 - 38.3 = 2.2 (hundreds) = 220
None of the provided options (440, 445, 450, 460) match the calculated difference of 220. There might be an error in the answer options provided.
The correct difference is 220.
But since it's not in the options, there might be a mistake in the provided options.
Let's re-calculate the difference in hundreds.
School A: 4.2 + 7.7 + 10.4 + 6.5 + 9.5 = 38.3 (hundreds)School B: 4.7 + 5.3 + 7.9 + 10.7 + 11.9 = 40.5 (hundreds)
Difference: 40.5 - 38.3 = 2.2 (hundreds)
Difference in numbers: 2.2 * 100 = 220
Let's check the options again.
The closest option is 1. 440, which is incorrect.
The correct answer should be 220, but it is not among the options.
There is an error in the provided answer options.
Final Answer: The final answer is 220 (but not in the given options).
