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%
Correct Answer: Option D
Explanation
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%
