A certain number of persons are standing in a row facing south (not necessarily in the same order). A is 13th person from left end. Four people stand between A and Z. Z is second person from one of the end. How many persons are standing in the row?
Show answer & explanation
Correct answer: C
Explanation
Z is 18th from the left and second from the right, so we can use this formula to find the total number:
Total people = (position from left + position from right) – 1
Z's position from the left = 18
Z's position from the right = 2
Total people = (18 + 2) – 1 – 19
Conclusion:
There are a total of 19 people standing in the line.
The correct option is: 3) 19
