Common solution for the set:

From the given mother data, we have

Condition 1:

R is not advertised during a given week unless Q is advertised during the immediately preceding week.

Q ⟵ R

Condition 2:

P is not advertised during a given week unless either R or V is also advertised that week.

P P

R or V

Condition 3:

S is advertised during one of the first two weeks.

S = Week 1 or 2

Condition 4:

V is one of the products advertised during week 3.

The product that is advertised twice is advertised during week

4 but is not advertised during week 3.

Week 3 = V

Week 3 = Product that is advertised twice cannot be advertised in week 3.

Answers 1: (C)

The two possible cases can be

Week 1 = Q, S

Week 2 = T, R

Week 3 = V, P

Week 4 = T, U

Week 1 = Q, T

Week 2 = S, R

Week 3 = V, P

Week 4 = T, U

The correct option is (C).

Answers 2: (B)

R should come after Q so, (A) and (E) are eliminated. P cannot be with U, so (C) is also eliminated. (D) cannot be the correct choice as S is not present in the first 2 weeks.

The correct option is (B).

Answers 3: (A)

P and Q as well as Q and R can never be together, so (B) and (C) are eliminated.

S and V cannot be together otherwise V is in the third week and it is not the repeated element, hence (E) is eliminated.

Q and V cannot be together otherwise R would have to come before Q, hence (D) is eliminated.

Hence U and V can be together.

The correct option is (A).

Answers 4: (B)

R can occupy only 2nd or 3rd or 4th weeks as it comes after Q.

Similarly, Q can occupy only 1st, 2nd or 3rd week.

T is given to be in week 3.

S also can occupy only 1st or 2nd week.

Hence T becomes the suitable choice among the answer options.

The correct option is (B).
