A King has unflinching loyalty from eight of his ministers M1 to M8, but he has to select only four to make a cabinet committee. He decides to choose these four such that each selected person shares a liking with at least one of the other three selected. The selected persons must also hate atleast one of the liking of any of the other three persons selected.
Explanation: likings: M1 = F + S; M2 = S + D; M5 = D, M6 = F. At least one liking is shared. Dislikes: M1 = G, M2 = F, M5 = 5 + M, M6 = 5 + M. Since G is not in the liking list, choice (a) is wrong. Continue checking. Only M1, M2, M4 and M7 (liking = F + S + D + M +
G, dislike = G + F + D + F) meets all the requirements.

In a “keep-fit” gymnasium class there are fifteen females enrolled in a weight-loss program. They all have been grouped in any one of the five weight-groups W1, W2, W3, W4, or W5. One instructor is assigned to one weight-group only. Sonali, Shalini, Shubhra, and Shahira belong to the same weight-group. Sonali and Rupa are in one weight-group, Rupali and Renuka are also in one weight-group. Rupa, Radha, Renuka, Ruchika, and Ritu belong to different weight-groups. Somya cannot be with Ritu, and Tara cannot be with Radha. Komal cannot be with Radha, Somya, or Ritu. Shahira is in W1 and Somya is in W4 with Ruchika. Sweta and Jyotika cannot be with Rupali, but are in a weight-group with total membership of four. No weight-group can have more than five or less than one member. Amita, Babita, Chandrika, Deepika, and Elina are instructors of weight-groups with membership sizes 5, 4, 3, 2 and 1, respectively.
Explanation: Radha cannot be in W1 or with Tara or Komal. This leaves her to be in the group with membership 1, so Elina is her instructor.
