• D. 4

Answer 1

Answer:

A. 2

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:

1	2	3	4	5	6
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:

1	2	3	4	5	6
E	G	F	R	Q	S

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
