Answer: A Option B and D are wrong because building K is coming after F. Option C is wrong because F is coming in the end whereas it has some priority mail and it should not come in the last position.
Q. No. 2:
If D is the only building receiving priority mail, which of the following lists the buildings in an order, from first to sixth, in which they can receive their mail ?

If only one building is to receive priority mail, and, as a result, H can be earlier than fourth in the order of buildings, which of the following must be the building receiving priority mail that day ?
Answer: C If H cannot come earlier than 4th place, this means the first three places are occupied by some priority mail. Again, we know that E and D must be delivered before M. So, only such destination could be M.
Q. No. 4:
If the sequence of buildings to which mail is delivered is H, K,E,D,M,F and if M is receiving priority mail, which of the following is a complete and accurate list of building that must also be receiving priority mail ?

Which of the following is a possible assignment of student-group to the class ?
Answer: C Option A is wrong because O and S are together. Option B is wrong because M is assigned with two others. Option D is wrong because N and T are schedules at different timings.

Exactly one of the products will be a members of two of these four pairs. None of the other products gets repeated in any pair. Further , the following constraints must be observed: 1). J is not advertised during a given week unless H is advertised during the immediately preceding week. 2). The product that is advertised twice is advertised during week 3. 3). G is not advertised during a given week unless either J or O is also advertised that week. 4). K is advertised during one of the first two weeks. 5). O is one of the products advertised during week 3.
Q. No. 1:
Which one of the following could be the schedule of the advertisements?
A :
Week 1: G, J; week 2 : K, L; week 3: O, M; week 4: H, L
B :
Week 1: H, K; week 2: J, G; week 3: O, L; week 4: M, K
C :
Week 1: H, K; week 2: J, M; week 3: O, L; week 4: G, M
D :
Week 1: H, L; week 2: J, M; week 3: O, G; week 4: K, L
Answer: B From the given mother data we have H <-- J G G J or O K = Week 1 or 2 Week 3 = O Week 4 = product that is advertised twice. J should come after H so, (a) is eliminated. G cannot be with M, so (c) is also eliminated. (d) cannot be the correct choice as K is not present in the first 2 weeks. So option (b) is the correct choice.
Q. No. 2:
If L is the product that is advertised during two fop the weeks, which one of the following is a product that MUST be advertisement during one of the weeks in which L is advertised?
Answer: C From the given mother data we have
H <-- J
G G
J or O
K = Week 1 or 2
Week 3 = O
Week 4 = product that is advertised twice. The two possible cases can be Week 1 = H,K Week 2 = L,J Week 3 = O,G Week 4 = L,M Or Week 1 = H,L Week 2 = K,J Week 3 = O,G Week 4 = L,M So, option (c) is correct
Q. No. 3:
Which one of the following is a product that could be advertised in any of the four weeks?
Answer: B From the given mother data we have
H <-- J
G G
J or O
K = Week 1 or 2
Week 3 = O
Week 4 = product that is advertised twice. One more case can be Week 1 = H,K Week 2 = G,J Week 3 = O,L Week 4 = K,M So. L can occupy any place.
Q. No. 4:
Which one of the following is a pair of products that could be advertisement during the same week?
Answer: A From the given mother data we have
H <-- J
G G
J or O
K = Week 1 or 2
Week 3 = O
Week 4 = product that is advertised twice. G and H as well as H and J can never be together, so (b) and (c) are eliminated. K and O cannot be together other wise K cannot be in the first two weeks. H and O cannot be other wise J would have to come before H. Hence M and O can be together.
