Q: Five friends are sitting in a row. A is to the left of B but to the right of C. D is to the right of A. Who is sitting in the middle?

Solution: The order is C, A, B, D. A is in the middle.

Steps: 9

Step 1: Identify the positions based on the clues given.
Step 2: The first clue says 'A is to the left of B'. This means A comes before B.
Step 3: The second clue says 'A is to the right of C'. This means C comes before A.
Step 4: From the first two clues, we can say C comes before A, and A comes before B. So far, we have C, A, B.
Step 5: The third clue says 'D is to the right of A'. This means D comes after A.
Step 6: Now we can add D to our order. Since D is to the right of A, the order becomes C, A, B, D.
Step 7: Count the positions: C is 1st, A is 2nd, B is 3rd, and D is 4th.
Step 8: The middle position in a row of five is the 3rd position.
Step 9: Therefore, A is in the middle.
