In a queue, Ali is 7th from the front and 12th from the back. How many people are in the queue?
Correct answer: A. 18
- A. 18
- B. 19
- C. 20
- D. 17
Explanation
Adding the two positions counts Ali twice, so the total is 7 plus 12 minus 1, which is 18. Forgetting to subtract the one is the standard error and gives 19. The same formula applies to any single object counted from both ends.
