Same answer and same approach as AmoyV
The problem is actually testing the concept of average and Maxima/Minima....
Let all the values be 135 , so the average will be 135/6 => 22.5 ( Minima )
Let all the values be 164, so the average will be 164/6 => 27.3 ( Minima )
Hence answer will be (C) { any number between the maximum and minimum value.... }
