wrong ans (Question: 62462.0 )

c=d is true

Question:
DIRECTIONS: In all the questions that follow different symbols have been used with different meanings. For each set of questions you have to assume given statements to be true and then decide which of the two given conclusions is/are definitely true. 


In the following questions, these symbols @,@,=,©,© are used with the following meaning:

P @ Q means P is greater than Q. 

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

P = Q means P is equal to Q.

P © Q means P is smaller than Q.

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


Choose correct answer as given in options.

Statements: 
A @ B, B © C, C ©  D

Conclusions:

I. A @ D    

II. C = D

Options:
A) Only conclusion I is true.
B) Only conclusion II is true.
C) Either conclusion I or conclusion II is true.
D) Neither conclusion I nor conclusion II is true.
E) Both the conclusions are true.
Solution:

Ans (d): 

Statements: A > B, B < C, C < D

Conclusions: I. A> D   II. C = D

For conclusion I, all statements are relevant. Combining B < C and C < D. 

We get B < C < D which means B < D. But we cant combine this with A > B because in both of them B is the smaller number (tip points to B in both cases). 

Conclusion II iss obviously false because C and D are not equal to anything in the given question. (tip 7 : quick method)
