In a class of 40, if Jane ranks 24th from the last, what is her position from the top?

To determine Jane's position from the top when she ranks 24th from the last in a class of 40 students, we need to calculate how many students are ranked below her. If Jane is 24th from the last, it means that there are 23 students who are ranked below her.

To find her rank from the top, we subtract her rank from the last (24th) from the total number of students (40). The calculation is as follows:

1. Total students = 40

2. Rank from the last = 24

3. Rank from the top = Total students - Rank from the last + 1

So, the calculation is:

40 - 24 + 1 = 17.

This means Jane is ranked 17th from the top. The correct response is therefore 17th, which corresponds to the choice indicating that she is in that position.
