Concept:This is a linear arrangement puzzle. We need to place seven people in a row facing north based on given positional clues.
Explanation:Step 1: Only five people sit to the right of A. Since there are seven seats (positions
1 to
7 from left to right), A must be at position
2.
Step 2: Only five people sit to the left of B, so B must be at position
6.
Step 3: F is the immediate neighbour of both G and E. So F sits between G and E, forming a block of three consecutive seats: either (G, F, E) or (E, F, G).
Step 4: C sits second to the left of E. This means there is exactly one person between C and E, with C to the left of E. Possible pairs: (C at
1, E at
3), (C at
3, E at
5), or (C at
5, E at
7).
Now, test the possible cases. Consider (C at
1, E at
3). Then E is at
3. For F to be adjacent to E, F can be at
2 or
4. Position
2 is already A, so F must be at
4. Then F is adjacent to G, so G must be at
5. This gives the block: E(
3), F(
4), G(
5). The remaining empty positions are
7 for D. Check: C at
1 and E at
3 – exactly one person (A at
2) between them, so C is second left of E. All conditions satisfied.
Thus, G sits at position
5. People to the left of G are at positions
1,
2,
3,
4: C, A, E, F. That is four people.
Other possibilities lead to contradictions, so this arrangement is correct.
Answer:Four people sit to the left of G. (Option C)
