Question:

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


P © Q means P is either smaller than or equal to Q.

P % Q means P is smaller than Q.

P@ Q means P is equal to Q.

P * Q means P is either greater than or equal to Q.

P $ Q means P is 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 below them is/are definitely true?

Statements:

M % T, T $ K, K © D


Conclusions:

I.  T $ D


II.  D $ K

Options:
A)

If only Conclusion I is true

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 Conclusion I and II are true
Solution:

Ans: (d)

Given that,

P © Q ⇒P ≤ Q

P * Q  ⇒P ≥ Q

P % Q ⇒P < Q 

P $ Q  ⇒P > Q

P@ Q ⇒P = Q

Statements:

M < T,  T > K,  K ≤ D

            M < T

K < T

K < D

Conclusions:

I. T $ D ⇒T > D ………. (false)

II. D $ K ⇒ D > K………. (false)

So it is clear that neither Conclusion I nor II is true.
