Logical Reasoning Set-1 (Level-3)

Answers 1: (d) To solve this set, first of all scroll through all the clues given to you so as to get a clear picture of the scenario given. Now since the 6th clue has 3 members, hence for forming the largest team we should be including H,I and J. Now after choosing them, check the remaining clues again and see who else we can pick. From clue 4, it is obvious that we cannot select B as B & I cannot be the members of the same team. Since B is not selected, from clue 3, we can pick D and from clue 5, we cannot pick A since if we pick A then we would have to pick B too, which of course is not the case. From clue 1, since we have picked up H, hence we cannot pick E or G since exactly one of E,G or H could have been picked. Now from clue 2, we can pick either of C or F. Hence the final combination would look like – H, I, J, D, C/F. Hence size of the largest team would be 5 The correct option is (d).

Answers 2: (e) If a team which includes A is to be selected, then from clue 5, we need to take B as well. Since we will have to take B, from clue 4, we cannot take I and then from clue 6, we cannot take HJ as well. Now from clue 1, we can take one of E or G and from clue 2 we can take C or F. Hence the possible combination of team will be A, B, E/G, C/F that is, 4 members. The correct option is (e).

Answers 3: (e) If a team includes D, it cannot include B and therefore, not even A (as evident from clues 5 and 3). According to condition (1), one out of EGH to be included and as per condition (2), one out of CF is to be selected. So, following cases are possible: If we select E- EFD or ECD If we select G- GFD or GCD If we select H- HIJCD or HIJFD Hence, the total number of possible cases are 2 + 2 + 2 = 6. The correct option is (e).

Answers 4: (a) We can form a team of size 3 by taking any member out of C, D, E, F. But, B cannot be a part of the team of size 3, because of the following reasons. From conditions (1) and (2); one of E, G, H and one of C, F are to be selected. But from statement (3), since (A, B) are always together, hence, B cannot be included in a team of 3 members as then A & B both will make the group members numbers to exceed 3. The correct option is (a).

Hence the final combination would look like – H, I, J, D, C/F. Hence C can be a member of the team with size 5. The correct option is (c).
