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 : J c P, P $\$$ N, J pounds H
Conclusions:
I. J c N
II. H @ P

• 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 $\$$
J = P . . .(i), P $\ge$ N . . . (ii), J $\ne$ H (iii) From (i) and (ii), we get, J = P $\ge$ N $\Rightarrow$ N
I may be true but not necessarily so.
From (i) and (iii), P = J $\Rightarrow$ H $\Rightarrow$ P $\#$ H.
Hence, again II may be true but H < P may be another possibility. Hence, II is not true.
