Question

In the following questions, the symbols $\delta$, $\star$, %, @ and $\#$ are used with the following meaning as illustrated.
'A % B' means 'A is neither greater than nor equal to B'.
'A $\#$ B' means 'A is neither smaller than nor equal to B'.
'A $\delta$ B' means 'A is neither smaller than nor greater than B'.
'A $\star$ B' means 'A is not smaller than B'.
'A @ B' means 'A is not greater than B'.
Now, in each of the following questions assuming the given statements to be true, find out which of the three conclusions I, II and III given below them is/are definitely true and give your answer accordingly.
% $\Rightarrow <$, @ $\Rightarrow$ $\le$ $\#\Rightarrow >$, $\delta$ $\Rightarrow$ =, $\star$ $\Rightarrow$ $\le$
Statements
W $\star$ X; X $\#$ Y; Y $\$$ Z
Conclusions
I. W $\star$ Z
II. W @ Z

• A. If only conclusion I is true
• B. If only conclusion II is true
• C. If either conclusion I nor 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 nor II is true

Given statements
W $\star$ X $\Rightarrow$ W < X ...(i)
X $\#$ Y $\Rightarrow$ X $\le$ Y ...(ii)
Y $\$$ Z $\Rightarrow$ Y > Z ...(iii)
After combining these statements, we get W < X $\le$ Y > Z
I. W $\star$ Z $\Rightarrow$ W < Z
II. W @ Z $\Rightarrow$ W $\ge$ Z
So, either conclusion I nor II is true.
