Question

How many persons are sitting between C and M?

• A. Two
• B. Three
• C. Five
• D. Four

Hint:

When arranging people with given constraints like positions and direction, first fix the known positions based on extreme end constraints and then use the relative positions to fill in the remaining spots.

Answer 1

The Correct Option is C

We know: - C sits second from one of the extreme ends, so \(C\) must be in position \(2\) or \(8\).
- Two persons sit between \(C\) and \(M\).
- M sits third to the left of \(D\), which fixes the position of \(M\) relative to \(D\).
- \(N\) sits 2nd to the right of \(M\).
- The immediate neighbors of \(M\) face opposite to \(M\), meaning they face South since \(M\) faces North.
- \(O\) sits second to the right of \(N\).
- P is an immediate neighbor of \(O\).
- Persons sitting in an extreme end are facing opposite directions to each other.
After constructing the arrangement, it turns out that there are \(\boxed{5}\) persons sitting between \(C\) and \(M\).
