Discussion
A team of three is to be selected from six persons - Pavan, Sravan, Raghavan, Aman, Dhawan and Bhavan, such that if one of Pavan and Sravan is selected then the other must not be selected. If one of Raghavan and Dhawan is not selected then the other must not be selected. If Aman is not selected then who must be selected ?
Answer: C
If Aman is not selected, Raghavan must be selected.
Without Aman, the team of three comes from Pavan, Sravan, Raghavan, Dhawan and Bhavan. Pavan and Sravan cannot both be chosen, and Raghavan and Dhawan go together or not at all.
If Raghavan and Dhawan were both left out, the team would have to be Pavan, Sravan and Bhavan, which breaks the first rule. So Raghavan and Dhawan are both in, and the third member is any one of Pavan, Sravan or Bhavan.
Bhavan and Pavan are each only one possible choice for the third place, so neither must be selected. Since Raghavan always is, 'None of the above' is wrong.
