    Question

    In a class, 3/5 of the students are girls and rest are

    boys. If 2/9 of the girls and 1/4 of the boys are absent. What part of the total number of students are present?
    A 23/30 Correct Answer Incorrect Answer
    B 23/36 Correct Answer Incorrect Answer
    C 18/49 Correct Answer Incorrect Answer
    D 17/25 Correct Answer Incorrect Answer

    Solution

    Let the total number of students in a class be x ∴ According to the question, Number of girls = 3/5 x and number of boys = x - 3/5 x = 2/5 x Number of girls who are absent = 3/5 × 2/9 x = 6x/45 and number of boys who are absent = 2/5 × 1/4 x = x/10 ∴ Total number of students who are present = x - 6x/45 - x/10 = (90x - 12x - 9x)/90 = 69x/90 = 23x/30 ∴ The 23/30 part of the students are present in the class.
