    C 540 Correct Answer Incorrect Answer
    D 375 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Number of boys = (4/10) × 1000 = 400

    Number of girls = (6/10) × 1000 = 600

    Required number of students = (3/4) × 400 + (2/5) × 600 = 300 + 240 = 540
