The following pie chart shows the distribution of the percentage of students in various courses at the university. The total number of students (boys and girls only) in the university is 7000.  
    A 25% Correct Answer Incorrect Answer
    B 29% Correct Answer Incorrect Answer
    C 23% Correct Answer Incorrect Answer
    D 27% Correct Answer Incorrect Answer

    Solution

    Total students = 7000
    B.Com students = 20% of 7000 = 1400
    B.Sc C.Sci students = 25% of 7000 = 1750

    Girls in B.Com = 60% of 1400 = 840
    Girls in B.Sc C.Sci = 60% of 1750 = 1050

    Total girls = 840 + 1050 = 1890
    Percentage = (1890 / 7000) × 100 = 27%
