Question

A, B, C and D are sitting around a circular table facing the centre. Who sits to the immediate right of A?

Statements:
(I) C sits to the immediate left of A; only one person sits between C and D.
(II) Only one person sits between A and B; C sits to the immediate right of B.

Accepted Answer

**Solution:**

1. **Analyze Statement I:**
   - C sits immediately to the left of A.
   - Only one person sits between C and D.

Since all are facing the centre, immediate left means counter-clockwise direction.

Possible arrangements:
   - Case 1: A-D-C-B
     - Here, B is immediately right of A.
   - Case 2: C-D-A-B
     - Here also, B is immediately right of A.

In both cases, B is to the immediate right of A.

**Therefore, Statement I alone is sufficient.**

2. **Analyze Statement II:**
   - Only one person sits between A and B.
   - C sits immediately to the right of B.

Possible arrangements:
   - Case 1: B-D-A-C
     - Here, C is immediate right of A.
   - Case 2: A-D-B-C
     - Here, D is immediate right of A.

Different answers arise for who is immediate right of A.

**Therefore, Statement II alone is not sufficient.**

3. **Combine Statements:**
   Since Statement I alone suffices and Statement II does not, the correct choice is option 1.

**Answer:** Data in statement I alone is sufficient to answer the question while data in statement II is not.
