Five friends, P, Q, R, S, and T, are standing in a line. P is to the right of Q but to the left of R. S is to the left of T. What is the correct order from left to right?
In a coded relation, if P × Q means P is the mother of Q, P ÷ Q means P is the son of Q, and P + Q means P is the daughter of Q, what is the relationship of R if P × R ÷ Q = true?
