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.
If (i) P is taller than Q ; (ii) R is shorter tan P; (iii) S is taller than T but shorter than Q, Then who among them is the tallest ?
Justification: In terms of height, we have : Q < P, R < P, T < S, S < Q. So, the sequence becomes : T < S < Q < R < P or T < S < R < Q < P. Whichever may be the case, P is the tallest.
