Five houses P, Q, R, S and T are in a row facing North. S is between T and Q. R is to the immediate right of Q. T is to the immediate right of P. Who is in the middle?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → S
All five face North, so their right is our right. The two “immediate right” clues give two fixed pairs, and S must stand between them.
T is to the immediate right of P: the pair P T
R is to the immediate right of Q: the pair Q R
S is between T and Q, so the two pairs stand on either side of S: P T S Q R, or Q R S P T
In both rows S is the third of the five, so S is in the middle.
