Question

Class Number: Betsy and Bill are classmates and their roll numbers are consecutive. If the sum of their roll numbers is 63 and Betsy has the smallest roll number, then the roll number of Bill is?

Answer 1

Explanation:

If their numbers are consecutive, then that means that their numbers follow each other continuously in order. (Ex: 1, 2, 3, 4, 5, and so on.)

31 + 32 = 63

If Betsy has the smaller roll number, that would mean that she rolled the 31, leaving Bill with the 32.

So, Bill's roll number is 32.
