Question

Directions: In the following questions, the symbols $\delta$ @ copyright $\%$ and $\ast$ are used with the following meaning as illustrated below.
'P copyright Q' means 'P is not smaller than Q'.
${}^{\prime }P\%Q^{\prime }$ means 'P is neither smaller than nor equal to Q'.
${}^{\prime }P\ast Q^{\prime }$ means 'P is neither greater than nor equal to Q'.
${}^{\prime }P\delta Q^{\prime }$ means 'P is not greater than Q'.
'P @ Q' means 'P is neither greater than nor smaller than Q'.
Now in each of the following questions assuming the given statements to be true, find which of the three conclusions I, II III and IV given below them is/are definitely true and give your answer accordingly
Statements: $D\delta T$ T @ R, R copyright M, $M\%K$
Conclusions:
I. R @ D
II. $R\%D$
III. $K\ast T$
IV. $M\delta T$

• A. Only either I or II is true
• B. Only III and IV are true
• C. Only either I or II and III are true
• D. Only either I or II and IV are true
• E. Only either I or II and III and IV are true

Answer 1

The correct option is E Only either I or II and III and IV are true

$\begin{array}{ccc}\delta \Rightarrow \le & \%\Rightarrow >& \ast \Rightarrow <\\ copyright\Rightarrow \ge & @\Rightarrow =& \end{array}\Rightarrow D\le T$
T @ R $\Rightarrow T=R$
R copyright M $\Rightarrow R\ge M$
$M\%K\Rightarrow M>L$
So, $D\le T=R\ge M>K$
Conclusions:
I. R @ D $\Rightarrow R=D$ Either I or II
II. $R\%D\Rightarrow R>D$
III. $K\ast T\Rightarrow K<T$ (True)
IV. $M\delta T\Rightarrow M\le T$ (True)
So, either I or II and III, IV are true.
