  6. Direction: The line chart given below shows the percentage distribution of total number of students in a college who likes different subject to read. Study the following chart carefully and answer the questions given below. Each student in the collage likes only one subject.

  7. The number of students who like math and history together is how much more or less than total number of students who likes science and English together ?
    400
    200
    500
    300
    480
    Option B
    Total number of students who like math and history = 2500 * (25 + 15/100) = 2500 * 40/100 = 1000
    Total number of students who like science and English together = 2500 * (30 + 18/100) = 2500 * 48/100 = 1200
    Difference = 1200 – 1000 = 200

     

  8. What is the average number of students who like science and geography ?
    525
    600
    400
    425
    500
    Option A
    Total number of students who like science and geography = 2500 * 30 + 12/100 = 1050
    average = 1050/2 = 525

     

  9. The number of students who like English is what percent more or less than the number of students who like geography ?
    40%
    20%
    25%
    50%

    percentage = 18 – 12/12 * 100 = 50%

     

  10. If the ratio of boys to girls students who like math and science is 4 : 1 and 3 : 2 respectively, then what is the difference between number of boys who like math and science ?
    60
    40
    65
    50
    75
    Option D
    Total number students who like math = 2500 * 25/100 = 625
    boys who likes math = 625 * 4/5 = 500
    Total number of students who like science = 2500 * 30/100 = 750
    boys who like science = 750 * 3/5 = 450
    Difference between the number of boys who like math and science = 500 – 450 = 50

     

  11. What the difference between the number of students who like science and the number of students who like English ?
    180
    300
    400
    350
    240
