    If each school has a total of 1,200 students, calculate

    the exact number of boys and girls in School Q. Then determine what percentage of the total number of boys across all five schools are from School Q.

    C 22.5% Correct Answer Incorrect Answer
    D 24% Correct Answer Incorrect Answer
    E 26.4% Correct Answer Incorrect Answer

    Solution

    Number of boys in School Q = 1,200 * (55 / 100) = 660 Number of girls in School Q = 1,200 * (45 / 100) = 540 Now calculate the total number of boys across all schools: School P: 1,200 * (48 / 100) = 576 School Q: 660 School R: 1,200 * (60 / 100) = 720 School S: 1,200 * (50 / 100) = 600 School T: 1,200 * (53 / 100) = 636 Total boys across all schools = 576 + 660 + 720 + 600 + 636 = 3,192 Percentage of boys from School Q = (660 / 3,192) * 100 ≈ 20.7%
