Question

Seven friends C, D, E, P, Q, R and S are sitting around a circular table facing the centre of the table. Only R sits between D and S. S sits third to the left of P. C sits to the immediate left of P. E is not an immediate neighbour of S. How many people sits between Q and E when counted from the right of E?

• A. One
• B. Three
• C. None
• D. Two

Answer 1

Answer:

D. Two

2 people sit between Q and E when counted from the right of E.

1. S sits third to the left of P: Place P at the bottom (position 1). Counting 3 places to the left (clockwise), place S at position 4.

2. C sits to the immediate left of P: Since everyone faces the centre, immediate left of P means moving 1 place clockwise. Place C next to P at position 2.

3. Only R sits between D and S: We know S is at position 4. Its neighbors are positions 3 and 5. Position 3 is next to C (position 2), and position 5 is on the other side. Since R must be between D and S, they must fill positions 3 and 5.

4. E is not an immediate neighbour of S: S is at position 4. The remaining empty spots for E are positions 6 and 7. Since E cannot be next to S (ruling out position 5), R must be at position 5 and D must be at position 6.

5. Placing E and Q: Now positions 3 and 7 are left. Since position 3 is next to S, E cannot sit there. So E must sit at position 7. This leaves position 3 for Q.

The Final Circle Order (Clockwise)

• Position 1: P

• Position 2: C

• Position 3: Q

• Position 4: S

• Position 5: R

• Position 6: D

• Position 7: E

Finding the Answer

Counting from the right of E (counter-clockwise direction from position 7):

• The sequence goes from E $\rightarrow$ P $\rightarrow$ C $\rightarrow$Q.

• The people sitting between E and Q are P and C.

Therefore, there are exactly 2 people between them.
