Solution

To solve this problem, we first need to find out the total number of students standing to the left of Sarah and to the right of Alex.

  1. Alex is at the 42nd position from the left, so there are 41 students to his left.
  2. Sarah is at the 49th position from the right, so there are 48 students to her right.

Next, we add the number of students to the left of Alex, the number of students to the right of Sarah, and Alex and Sarah themselves.

  1. 41 (students to the left of Alex) + 1 (Alex) + 48 (students to the right of Sarah) + 1 (Sarah) = 91

Now, we subtract this total from the total number of students in the row.

  1. 75 (total students) - 91 = -16

Since we can't have a negative number of students, this means that Alex and Sarah are overlapping in the row, and there are 16 students between them.

So, there are 16 students standing between Alex and Sarah in the row.
