In such type of questions, a few essential criteria for selection of a group of items are given. The candidate has to keep these conditions in mind and make the required selection as per the directions given in each question.
Eight students A, B, C, D, E, F, G and H are planning to enjoy car racing. There are only two cars and following are the conditions :
(i). One car can accommodate maximum five and minimum four students.
(ii). A will sit in the same car in which D is sitting but H is not in the same car.
(iii). B and C can't sit in the same car in which D is sitting.
(iv). F will sit in the car of four people only alongwith A and E but certainly not with G.
Which of the following statements is superfluous for the above sitting arrangements ?
Consider two cars I and II.
A and D sit in the same car, say I.
H is not in the same car i.e. H is in car II.
B and C are not in the same car in which D is sitting i.e. B and C are in car II.
F sits along with A and E in the same car i.e. car I.
G is in the other car i.e. car II.
Thus, we have :
Car I → A, D, E, F
Car II → B, C, G, H
Clearly, Statement (i) is not necessary.
