‘A B’ means A is not greater than B
‘A % B’ means A is neither smaller than nor equal to B
‘A © B’ means A is neither greater than nor equal to B
‘A * B’ means A is neither greater nor smaller than B
‘A $ B’ means A is not smaller than B
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.
Give answer
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.

1.      (b) Given statements:
A %
B * C $ D Þ A > B = C ³
D   ………….(i)
E d G © D Þ E £ G < D………………….(ii)
Combining
(i) and (ii), we get
A
> B = C  ³ D >G ³
Thus,
B > G or G < B is true. Conclusion I (G % B
Þ G > B) is not true 
but A > E or
conclusions II (A % E) is true.



2.  Statements:
M © O

Conclusions:   I. U % M     II. S © U.

Ans:     (a) Given statement:


O d  U Þ M < O £ U …………(i)
Q d S d U Þ Q £ S £ U …………….(ii)
Combining
(i) and (ii), we get
M
< O £ U ³ S ³ Q
Thus,
M < U or U < M is true. Hence I (U % M Þ U>M) is true.

Again
S £ U is true. Hence II (S < U) may be true
but not definitely so.

Conclusions:   I. T % X                    II. U © T .

Ans:   (e) Given statements:

W *
X d U Þ W = X £ U ………….(i)
W ©
O % U Þ X < O > U
…………..(ii)
W ©
T % O Þ W < T > O
…………..(iii)
Combining
(i), (ii) and (iii), we get
W =
X £ U < O < T
Thus,
X < T or T > X is true.
Hence
I (T % X) is true.
Again,
U < T is also true.

Hence
II (U © T) is true.

4.  Statement:
T % U * V $ O % R © S © B % C
Conclusions:           I. U % R             II.

e
Ans:  (a) Given statement:

T %
U * V $ O % R © S © B % C
Þ T > U = V ³ O > R < S < B > C
Thus,
U > R is true. Hence I (U % R Þ U > R) is true.

Again,
we can’t compare O and B. Hence II (O d B Þ O £ B) is not true.'

5. Statements:
W © X
d S, X %
U ©W, U% Q

Conclusions:     I. Q © W           II. X % Q.

W ©
X d S Þ W < X £ S …………..(i)
X %
U © W Þ X > U < W
…………(ii)
U %
Q Þ U > Q ……………(iii)
Combining
(i), (ii) and (iii), we get
Q
< U < W < X £ S

Thus,
Q < W and I is true. Also, X > Q and II is true.
