Eight persons – D, E, G, H, K, L, S and T are sitting in a straight line facing north. E sits second from the left end of the row. No one is sitting between H and E. G sits fourth to the right of H. K is sitting immediate left of G. Only two persons sit between K and D. L is sitting third to the right of S. How many persons are sitting between S and T?

Given : Eight persons – D, E, G, H, K, L, S and T are sitting in a straight line facing north.

Explanation :

1) E sits second from the left end of the row.

2) No one is sitting between H and E.

As position of E with respect to E is not known yet, therefore there are two possible positions for H.

• Case - (1) :

• Case - (2) :

3) G sits fourth to the right of H.

4) K is sitting immediate left of G.

• Case - (1) :

• Case - (2) :

5) Only two persons sit between K and D.

6) L is sitting third to the right of S.

As there is possible position for D is case - (2), therefore case - (2) is eliminated.

After positioning D, L and S only one position is left which will be occupied by the only person left i.e T.

• Case - (1) :

Thus, according to the final arrangement four people i.e K, G, L and D are sitting between S and T.

Hence, "More than three" is the correct answer.
