Direction: In the following questions, the symbol @ , $, *, # and δ 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 equal to Q’.
‘P # Q’ means ‘P is neither greater than nor equal to Q’.
‘P δ Q’ means ‘P is neither greater than nor smaller than Q’.
‘P * Q’ 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 four conclusion I, II , III and IV given below them is/are definitely true and given your answer accordingly.
Statements:
D # R, R*K, K@F, F$J
Conclusion:
I. J#R
II. J#K
III. R#F
IV. K@D
(A) Only I, II and III are true
(B) Only II, III and IV are true
(C) Only I, III and IV are true
(D) All I, II, III and IV are true
(E) None of these

Direction: In these questions the symbols $ , @ , £ , • and # are used with different meanings as given below :
' X $ Y ' means X is neither greater than nor smaller than Y '
 ' X @ Y ' means X is neither greater than nor equal to Y '
 ' X £ Y ' means X is neither smaller than nor equal to Y '
 ' X• Y ' means X is not smaller than Y '
' X # Y ' means X is not greater than Y '
( 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    

Statements: V• D, D £ T, K $T, K # F
 Conclusions:
I. D£K
II. T• F

Two statements are followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they do not conform to real-word knowledge, decide which of the conclusion(s) logically follows from the statements.

Statements:

All ponds are pools

Some wells are ponds.

Conclusions;

I. Some ponds are not wells.

II. Some wells are pools

III. All pools are wells.

Statements
E=F˂G˂H
G ≥ I        
Conclusions I. H˃I
                    II. E≥I

In the question below, two statements are given followed by two conclusions numbered I and II. You have to take the two statements to be true even if they seem to be variance from the commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding the commonly known facts.
Statements: Some rings are circles.
                    No circle is a square.
Conclusion I. No ring is a square.
                   II. All rings are squares.

Direction: In these questions the symbols $ , @ , £ , • and # are used with different meanings as given below :
' X $ Y ' means X is neither greater than nor smaller than Y '
 ' X @ Y ' means X is neither greater than nor equal to Y '
 ' X £ Y ' means X is neither smaller than nor equal to Y '
 ' X• Y ' means X is not smaller than Y '
' X # Y ' means X is not greater than Y '
( 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    

Statements: S$ Q, Q@B, B• K, K # W
 Conclusions:
I. K# S
II. S@ W
