Who among the following is an immediate neighbor of B?
Study the following information carefully and answer the questions given below: Seven persons A, B, C, D, E, F and G are sitting in a row facing towards the north but not necessarily in the same order. Each one of them likes different colors i.e., white, orange, violet, cream, mustard, brown and pink but not necessarily in the same order. The one who sits immediate right of D likes pink.
