- option c is the answer.
s.shankar is watched by 4 people.....rajkumar hirani film is watched by 2 people and mani ratnam film by 1...then only the condition is satisfied....therefore option d is easily eliminated...guna watches either maniratnam movie or s.shankar movie therefore option a is eliminated.
in option b)viji and yamini watches the film together but since mani ratnam can be watched by only 2 people and 2 are given therefore it is also eliminated....hence option c is correct - 9 years agoHelpfull: Yes(6) No(1)
- (D) As it is the only case, which satisfies the condition "Exactly twice as many of the film buffs sees the S.shankar film as see the Rajkumar Hirani film".
Viji and Yamini= Mani Ratnam,
Rinku= Mani Ratnam
Madhu= Mani Ratnam.
So total of 4 watch Mani ratnam film.
Now since Guna sees either Rajkumar hirani film and Mani Ratnam film, and also Guna and rinku see different fims, So Guna see Rajkumar Hirani film.
Leela sees S.Shankar(already mentioned) and Isha can also see S.Shankar
