Question

Seven people, G, H, I, J, K, L and M, are sitting in a row, facing north(but not necessarily in the same order) . Only G sits to the left of J. Only four people sit between G and H. Only K sits between L and I, and L is not an immediate neighbour of H. How many people sit between M and J?

• A. Four
• B. Two
• C. One
• D. Three

Answer 1

Answer:

A. Four

Let’s place them step by step carefully.

“Only G sits to the left of J”

This means:

• G is immediately to the left of J
  So: G – J (adjacent pair)

  “Only four people sit between G and H”

Total people = 7
If 4 people are between G and H, they must be at extreme ends

Possible:

• G at position 1 and H at position 6
  OR

• H at position 1 and G at position 6

But since G–J must be together, only this works:

G at 1, J at 2, H at 6

“Only K sits between L and I”

So:
L – K – I OR I – K – L

“L is not an immediate neighbour of H”

H is at position 6
So L cannot be at position 5 or 7

Fill remaining positions

Positions:
1 G
2 J
3
4
5
6 H
7

Now place L, K, I (with one between them):

Valid placement:
I (3), K (4), L (5)
(Check: L not next to H? L is at 5, H at 6 → not allowed)

Try:

L (3), K (4), I (5)
(Check: L at 3, H at 6 → OK)

Remaining position → 7 → M

Final arrangement:

1 G
2 J
3 L
4 K
5 I
6 H
7 M

People between M and J

J is at 2, M is at 7
People between = positions 3, 4, 5, 6 → 4 people

Final Answer:

4
