There are 250 boys and 150 girls in a school, if 60% of the boys and 40% of the girls play football, what percentage of the school play football?
A
40.0%
B
42.2%
C
50.0%
D
52.5%
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Population of school = 250 + 150 = 400
60% of 250 = \(\frac{\text{60%}}{\text{100%}}\) x 250 = 150
40% of 150 = \(\frac{\text{40%}}{\text{100%}}\) x 150 = 60
Total number of students who plays football;
150 + 60 = 210
Percentage of school that play football;
\(\frac{210}{400}\) x 100% = 52.5%
