Question
Seven persons A, B, Y, Z, E, F and G are sitting in a
row facing north but not necessarily in the same order. Which of the following persons sit fourth to the left of Y? I. Y sits second to the right of A. Two persons sit between A and F. E sits second to the left of F. Only one person sits between G and B. Z sits left of E. II. Three persons sit between G and E. Either G or E sits at one of the extreme end. A sits left of F. B and A are immediate neighbours. Y sits right of E. Each of the questions below consists of a question and statements numbered I, IIÂ given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:Solution
From I, G / B > Z > G / B > A > E > Y > F
