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:
$B\ast K$
$K\$N$
$N\%R$
Conclusions:
I. $R\$K$
II. $R\ast K$

• 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 E Both conclusions I and II are true

Statements: $B\ast K\Rightarrow B<K,K\$N\Rightarrow K=N,N\%R\Rightarrow N\ge R$
Conclusions:
I. $R\$K\Rightarrow R=K$ (True)
II. $R\ast K\Rightarrow R<K$ (True)
