What is the difference between the total number of students in University A and the total number of students in University B?
Answer: B
Total students in University A = 20 + 30 + 25 + 35 = 110 thousand.
Total students in University B = 25 + 35 + 30 + 30 = 120 thousand.
Difference = 120,000 - 110,000 = 10,000.
