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%
45%
Option D

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
