Question

Directions: In the following questions, the symbols $\$,\%,\ast ,\delta$ and © are used with the following meaning as illustrated below.
${}^{\prime }P\%Q^{\prime }$ means 'P is not smaller than Q'.
${}^{\prime }P\ast Q^{\prime }$ means 'P is neither greater than nor equal to Q'.
${}^{\prime }P\delta Q^{\prime }$ means 'P is neither smaller than nor equal to Q'.
${}^{\prime }P\$Q^{\prime }$ means 'P is neither greater than nor smaller than Q'.
${}^{\prime }P\copyright Q^{\prime }$ means 'P is not greater than 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 is/are definitely true?

Statements:
$Z\delta D$
$D\copyright K$
$K\delta M$
Conclusions:
I. $M\ast D$
II. $Z\delta K$

• A. Only conclusion I is true
• B. Only conclusion II is true
• C. Either conclusion I or II is true
• D. Neither conclusion I nor II is true
• E. Both conclusions I and II are true

Answer 1

The correct option is D Neither conclusion I nor II is true

Statements: $Z\delta D\Rightarrow Z>D$ D © K $\Rightarrow D\le K,K\delta M\Rightarrow K>M$
Conclusions:
I. $M\ast D\Rightarrow M<D$ (False)
II. $Z\delta K\Rightarrow Z>K$ (False)
