Seven sisters P, Q, S, D, R, L and G are standing in a row facing north. L is standing to the immediate right of R who stands fourth to the right of G. Only S stands exactly between Q and D. D stands at the middle position. Who stands at the rightmost position?
Answer & explanation
Correct answer: option 1
Only S stands exactly between Q and D. D stands in the middle position.
CASE 1:
_ Q S D _ _ _
CASE 2:
_ _ _ D S D _
L is standing to the immediate right of R who stands fourth to the right of G.
CASE 1:
G Q S D R L _
CASE 2:
It is not possible because in this case, R will be at the extreme right end. So, L cannot stand at the immediate right of R.
So, the only position for P is at the extreme right end.
G Q S D R L P
∴ P is at the rightmost position.
