Correct Answer: $12:5$


Solution : Total number of students in arts = 600 + 550 + 550 + 700 = 2400
Total number of students in commerce = 200 + 250 + 300 + 250 = 1000
Number of given years = 4
Average total number of students in arts = $\frac{2400}{4}$ = 600
Average total number of students in commerce = $\frac{1000}{4}$ = 250
Required Ratio = $600:250 = 12:5$
The ratio of the average number of students in Arts to the average number of students in Commerce is $12:5$
Hence, the correct answer is $12:5$.
