Six people, E, F, G, Q, R and S, are sitting in a row facing north (but not necessarily in the same order) . Only two people sit to the right of R. Only two people sit between R and E. Only one person sits between E and F. F sits to the immediate left of R. S sits to the immediate right of Q. How many people sit between Q and G?

Answer:

A. 2

Read Explanation:

Let us arrange step by step.

Positions

Six seats in a row (facing north): 1 2 3 4 5 6

Step 1: Place R

  • Only two people sit to the right of R
    → R must be in position 4

    Step 2: Place F

  • F sits to the immediate left of R
    → F is in position 3

    Step 3: Place E

  • Only two people sit between R and E
    → With R at 4, E must be at position 1

  • Only one person sits between E and F
    → E (1) and F (3) have exactly one person between ✔️

So far:

E

F

R

Step 4: Place Q and S

  • S sits to the immediate right of Q

Available seats: 2, 5, 6
Only possible consecutive pair is 5 & 6

→ Q at 5, S at 6

Step 5: Place G

  • Remaining seat = 2

Final arrangement:

How many people sit between Q and G?

Q is at position 5
G is at position 2

People between them: positions 3 and 4 → 2 people


Answer: 2
