In such type of questions, clues are given regarding comparisons among a set of persons or things with respect to one or more qualities. The candidate is required to analyse the whole information, form a proper ascending / descending sequence and then answer the given questions accordingly.
(i). A, B, C, D and E are five friends.
(ii). B is elder to E, but not as tall as C.
(iii). C is younger to A, and is taller to D and E.
(iv). A is taller to D, but younger to E.
(v). D is elder to A but is shortest in the group.
If F, another friend, is taller than C, how many of them will be between F and E according to their height ?
In terms of age, we have :
E < B, C < A, A < E, A < D
So, we have : C < A < E < B < A < D.
In terms of height, we have :
B < C, D < C, E < C, D < A
Since no definite order of height can be obtained, so it cannot be determined for sure how many persons lie between F and E.
