Question

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 right of p ?

Answer 1

x is right of p as i solved

Answer 2

 _ _ _ _ _ _ be the six places.
A and P are at the extremes ⇒ A _  _ _ _ P or P_ _ _ _ A . As the question asks us who sits to the right of P, case 1 is not possible. 
Considering case-2, 
  P _  _ _ _ A. It is said that S and Z are at the center, so we get P _ S Z _ A or P _ Z S _ A. Both the cases are favorable, take any one of it. 
→ P _ S Z _ A. Since R is sitting to the left of A, we get P _ S Z R A. The only place where X can be seated is next to  P. The arrangement is P X S Z R A. So, X sits right of P
