In a queue, John is 13th from the front and Mary is 15th from the back. If there are 5 people between them, and John is ahead of Mary, what is the total number of people in the queue?
Show answer & explanation
Correct answer: A
Explanation
Distance between John and Mary
There are 5 people in between → so the difference in places is 5 + 1 = 6
So Mary's place from the front = 13 + 6 = 19
Total number of people
Formula: Total = (place from the front) + (place from the back) - 1
= 19 + 15 - 1
= 33
