Show the answer and the worked solution
Correct answer: B. 4
Worked solution
- The gap is 12 − 7 = 5 seats.
- Excluding both of them, the people between number 5 − 1 = 4.
Answer: 4.
The idea
Difference of positions minus one gives the count strictly between. Including one endpoint would give 5.
Shortcut. The people between sit in positions 8, 9, 10 and 11 — four of them.
Common trap. "5" — taking the gap 12 − 7 as the headcount, which includes Sunil's own seat.
