**A school has 800 students. The breakdown by gender and sport is as follows:** - $60\%$ of the students are boys; the rest are girls. - Among the boys: $25\%$ play Cricket, $35\%$ play Football, $20\%$ play Basketball, and the rest play Tennis. - Among the girls: $40\%$ play Cricket, $30\%$ play Football, $15\%$ play Basketball, and the rest play Tennis. Every student plays exactly one of these four sports. **Question.** Boys who play Tennis are what percent of the total student body?
A$10\%$
B$12\%$
C$15\%$
D$20\%$
Answer & Solution
Correct answer: B. $12\%$
Boys playing Tennis $= 100\% - (25 + 35 + 20)\% = 20\%$ of $480 = 96$.
As a fraction of the whole school: $\dfrac{96}{800} \times 100 = 12\%$.
