The ratio of average number of students in Science to the average number of students in Commerce is :
-
- 10 : 7
- 7 : 4
- 12 : 5
- 48 : 35
Correct Option: B
According to given bar graph , we have
Total number of students in Science ⇒ 400 + 400 + 450 + 500 = 1750
Total number of students in Commerce ⇒ 200 + 250 + 300 + 250 = 1000
Number of given years = 4
Required ratio = Average number of students in Science : Average number of students in Commerce
| ∴ Required ratio = | : | = 7 : 4 | 4 | 4 |
