From statement 1, 2, and 7 we can gather the following information:
Now, as per statement 2 Tanya will be interviewed either on Tuesday or Thursday and Sachin will be interviewed on either Saturday or Sunday.
If Tanya is interviewed on Thursday and Sachin is interviewed on Saturday then Gayatri must be interviewed on Sunday since statement 5 says at least a one day gap is required between Mahima and Gayatri's interview. So, Abhinav will have to be interviewed on Tuesday. [Case 1]
Similarly, If Tanya is interviewed on Thursday and Sachin is interviewed on Sunday then Gayatri must be interviewed on Saturday since statement 5 says at least a one day gap is required between Mahima and Gayatri's interview. However, Gayatri is asked questions on Indian Bankruptcy Code (IBC) (from statement 6) while the person interviewed on Saturday is asked admin law (statement 1) so this case is not possible.
If Tanya is interviewed on Tuesday and Sachin on Sunday then Gayatri will have to be interviewed on Thursday since she is asked about IBC and not admin law.
From statement 4 we know that the ones wearing blazers must be on consecutive days apart from the weekend. Also, Digivijay does not wear a blazer (statement 1) so the ones wearing a blazer can either be on Monday and Tuesday or Thursday and Friday. From statement 3 we know that the ones carrying files are interviewed before Thursday, so on any two of the days among Monday, Tuesday and Wednesday.
Even if one of the days is Wednesday, at least one person must carry a file on Monday and Tuesday. So, the ones wearing a blazer must be on Thursday and Friday.
In Case 1, upon placing the information we get the following:
However, as per statement 8, this is not possible. So, this case can be eliminated.
Similarly we can eliminate other cases. The only possible way, all the conditions are followed is:
So Option C is correct.
