Six friends P, Q, R, S, T and U are sitting in a straight line facing east. R is sitting exactly between P and T. Q is to the immediate right of T but to the left of S. U is not at the right end. Who is at the right end?
A
S
B
Q
C
T
D
R
Correct Option:
A
Explanation
R sits exactly between P and T, giving the relevant core order P–R–T. Q is immediately to the right of T and also to the left of S, producing P–R–T–Q–…–S. Since U cannot occupy the right end, S is at the right end.
