Question:

DIRECTIONS : In the following questions, the symbols #, $, @, * and © are used with the following meaning as illustrated below:


‘P # Q’ means ‘P is not smaller than Q’.

‘P $ Q’ means ‘P is neither smaller than nor greater than Q’.

‘P @ Q’ means ‘P is neither greater than nor equal to Q’.

‘P * Q’ means ‘P is not greater than Q’.

‘P © Q’ means ‘P is neither smaller than nor 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.

Conclusions

I. B $ M                         

II. B @ M

Options:

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
Solution:

Ans:     (d)

P # Q ⇒P  ≥ Q

P $ Q ⇒ P  = Q

P @ Q ⇒ P < Q

P * Q ⇒ P ≤ Q

P © Q ⇒ P > Q

 

Statements

B = K, K < D, D ≥ M

Therefore,

B = K < D

M ≤ D

Conclusions

I. B = M   (False)

II. B < M   (False)


So, neither conclusion I nor II is true.
