In a row of students, if A is 12th from the left and B is 15th from the right, and there are 7 students between them, find the maximum number of students in the row.
Show answer & explanation
Correct answer: C
Explanation
A = 12th from the left
B = 15th from the right
7 students between A and B
Find B's position from the left
If there are 7 students between A and B, the difference in their positions is:
7 + 1 = 8
Therefore, B's position from the left is:
12 + 8 = 20
Formula for total students:
Total = (position from the left) + (position from the right) - 1
= 20 + 15 - 1
= 34
