\( A, P, R, X, S \) and \( Z \) are sitting in a row. \( S \) and \( Z \) are in the centre. \( A \) and \( P \) are at the ends. \( R \) is sitting to the left of \( A \) . Who is to the left of \( X \) ?
Step-by-step Solution:
Assuming “to the left of A” means **immediately to the left**, the unique arrangement (left → right) is: $$ \begin{array}{cccccc} P & X & S & Z & R & A \end{array} $$
