chetan2u Hi Chetan, shouldn't the answer in the first part of the question be 'Yes'.
Since both median and mean are 80, it is clear that the 3rd value in a set of 5, would be 80.
Thus value(1) and/or value(2) could be less than 80, with value (3,4,5) being 80 and above.
So, we can successfully answer the first part of the question as 'no', given the above information.
Hence, the answer to the main question asked, should be 'Yes'.

Yes, that would be correct if it were DS. Here, the options are not questions but certain statements that should be true based on the basis of the information provided.
But, the wordings could be changed a bit. thank you
