B and A are immediate neighbours. C sits right of E. The question given below is followed by two statements numbered I and II. You have to decide whether the data provided in the statements sufficient to answer the question:Solution
From I. There will be two cases: G/BÂ Â Â Â Â Â Â DÂ Â Â Â Â Â Â Â Â Â Â Â G/BÂ Â Â Â Â Â Â AÂ Â Â Â Â Â Â Â Â Â Â Â EÂ Â Â Â Â Â Â Â Â Â Â Â Â CÂ Â Â Â Â Â Â Â Â Â Â Â F Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Case 1.
