Question

In each question, three statements showing relationships have been given, which are followed by two conclusions I and II. Assuming that the given statements are true, find out which conclusion(s) is/are definitely true.
Statements : N ? S, S @ P, P pounds M
Conclusions
I. S @ M
II. P c N

• A. if only conclusion I is true
• B. if only conclusion II is true
• C. if either I or II is true
• D. is neither I nor II is true
• E. if both I and II are true

Answer 1

The correct option is D is neither I nor II is true

In these questions the negative meaning of these symbols is given to establish the relation between A and B, which can be easily converted to its simple and positive meaning. Expressing them mathematically, we get, @ $\to$ > (greater than), c $\to$ (equal to), pounds $\to$ $\ne$ (means either greater than or smaller than, but no definite conclusion), ? $\to$ < (smaller than), and $\$$
N < S . . .(i), S > P . . . (ii), P $\#$ M (iii)
From (ii) and (iii), no definite relationship between S and M can be established. Hence I is not true. From (i) and (ii), we get, N < S > P no conclusion. Hence,II is not true.
