Q: If five friends are sitting in a row facing north, and A is to the left of B, C is to the right of A, and D is to the left of E, who is sitting in the middle?
Solution: The arrangement is A, C, B, D, E. C is in the middle.
Steps: 8
Step 1: Identify the friends: A, B, C, D, and E.
Step 2: Start with the first clue: A is to the left of B. This means A must be positioned before B.
Step 3: Next, use the second clue: C is to the right of A. This means C must be positioned after A.
Step 4: Now we have A, C, and B in that order: A, C, B.
Step 5: Use the last clue: D is to the left of E. This means D must be positioned before E.
Step 6: Combine the two parts: We can place D and E after A, C, and B. The only way to fit them is to place D before E.
Step 7: The final arrangement is A, C, B, D, E.
Step 8: Identify the middle position: In the arrangement A, C, B, D, E, the middle friend is C.
