y = 20, 5 - 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 ?
400200500300480Option 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 - What is the average number of students who like science and geography ?
525600400425500Option A

Total number of students who like science and geography = 2500 * 30 + 12/100 = 1050

average = 1050/2 = 525 - 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

percentage = 18 – 12/12 * 100 = 50% - 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 ?
6040655075Option 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 - What the difference between the number of students who like science and the number of students who like English ?
180300400350240Option B

Difference = 2500 (30 – 18/100)

= 2500 * 12/100 = 300
