Question

In the following questions, the symbols @ , copyright $\ast ,\%,$ and $ are used with the following meaning as illustrated below.
'P copyright Q means 'P is neither greater than nor smaller than Q'.
'P @ Q' means 'P is smaller than Q'.
${}^{\prime }P\$Q^{\prime }$ means 'P is greater than Q'.
${}^{\prime }P\ast Q^{\prime }$ means 'P is either smaller than or equal to Q'.
${}^{\prime }P\%Q^{\prime }$ means 'P is either greater than or equal to Q'.
Now, in each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/are definitely true?
Statements: J % N, N copyright D, D @ K
Conclusions
I.D copyright J
II. D @ J

• A. If Only Conclusion I is true
• B. If Only Conclusion II is true
• C. If Either Conclusion I or II is true
• D. If Neither Conclusion I nor II is true
• E. If Both Conclusions I and II are true

Answer 1

The correct option is C If Either Conclusion I or II is true

P copyright Q $\Rightarrow$ P = Q
P @ Q $\Rightarrow P<Q$
$P\$Q\Rightarrow P>Q$
$P\ast Q\Rightarrow P\le Q$
$P\%Q\Rightarrow P\ge Q$
Statements: $J\%N\Rightarrow N,NcopyrightD\Rightarrow N=D$, D @ K $\Rightarrow D<K$
So, $J\ge N=D<K$
Conclusions
I. D copyright J $\Rightarrow D=J$ (True)
II. D @ J $\Rightarrow D<J$ (True)
