Each of the six couples A through F watched exactly two of the following movies – Bahubali, Pushpa, KGF and Kabali. Following is the information known about them.

(ii) Neither B nor E watched Bahubali and B does not watch Pushpa.

(iv) A saw Kabali.

**PE 4 - Selection & Distribution | LR - Selection & Distribution**

Which of the movies does B watch?

- (a)
Pushpa and KGF

- (b)
Pushpa and Kabali

- (c)
KGF and Kabali

- (d)
Cannot be determined

Answer: Option C

**Explanation** :

Out of 4 movies, 6 different pairs can be formed. As no two couples watched the same set of movies, each of these 6 pairs will be watched by a different couple such that each movie would be watched by exactly three different couples.

From (ii) and (iii) we get B, E and F do not watch Bahubali. A, C and D watched Bahubali.

From (ii) B did not watch Pushpa either, hence B should have seen KGF and Kabali.

From (iii) A watched Kabali.

From (iv) F saw Pushpa and KGF

Now, C and D cannot see Kabali since A has already watched the combination of Bahubali and Kabali.

Now, out of C and D, one of them will watch Pushpa and the other KGF in any order.

Since 3 couples have to see Pushpa, E will see Pushpa. Also, E cannot watch KGF to avoid same combination as F, hence E will watch Kabali.

Hence, we get the following table:

∴ B watched KGF and Kabali.

Hence, option (c).

Which store sells the least number of brands?

- (a)
A

- (b)
B

- (c)
C

- (d)
Cannot be determined

Answer: Option C

**Explanation** :

We have 3 stores (A, B and C) selling 6 brands – Redmi (R), Vivo (V), Samsung (S), Xiomi (X), Oneplus (O) and Apple (Ap).

From (ii) 2 brands are sold by all three stores. These brands cannot be Redmi, Apple and Samsung since

From (iii) B does not sell Redmi, A does not sell Apple and C does not sell Samsung.

Also, from (viii) Vivo cannot be sold by all three stores. Hence, the two brands sold by all three stores are Oneplus and Xiomi.

From (v) A store must sell Redmi or Apple, but not both. Hence, store A must sell Redmi and B must sell Apple.

From (i) Out of these three stores, one sells five brands, another sells four brands and the third sells three brands.

From (iv) A sells more brands than C, hence C cannot sell 5 brands. Hence, either A or B will sell 5 brands and hence one of A or B will sell Vivo.

From (viii) Since Vivo is sold by exactly one othe stores, C will not sell Vivo but sell exactly one of Redmi or Apple. Hence, C sells exactly 3 brands.

∴ A or B sells 4 or 5 brands in any order. It means but both of them will sell Samsung.

Hence, we get the following table:

C sells the least number of brands.

Hence, option (c).
