Seven people, S, T, I, C, K, E and R, are sitting in a row, facing north. Only E sits to the left of K. Only four people sit between E and T. Only C sits between I and R, and I is not an immediate neighbor of T. Who sits at the extreme right of the line?
S
Number the seats 1 to 7 from left to right, all facing north.
"Only E sits to the left of K" means exactly one person (E) is to the left of K, so E is in seat 1 and K is in seat 2.
"Only four people sit between E and T" means E and T have four seats between them, so with E at seat 1, T is at seat 6.
The remaining seats 3, 4, 5 and 7 are for S, I, C and R.
"Only C sits between I and R" means I, C, R form a consecutive block; the only place for three consecutive empty seats among 3, 4, 5, 7 is seats 3, 4, 5, giving I = 3, C = 4, R = 5 (or the reverse), and S = 7.
The condition "I is not an immediate neighbour of T (seat 6)" is satisfied since I is at seat 3.
So seat 7, the extreme right, is occupied by S.
Hence, S sits at the extreme right of the line.
