Question 1- N(-)
| ＼
B(+) S — M(+) — A(-)
Since the gender of S is not known , options 1,2 and 3 are not necessarily true. Option 4 is true.
Question 2- A(-) ⇔ V(+)
Ι |
R — S(-) — T(+)
Since the gender of R is not known. Option 2 and 3 are not necessarily true. Reject option 4 because 4 is male.
Question 3- Make family trees of given expressions:
- N(-)
丨 ∖
V(-) L ㅡ D (+)
丨
C(+)
Here C is the nephew of D.
(2) L(-)
ㅣ ＼
V(+) N ㄧ D(+)
丨
C(+)
Here C is the nephew of D
(3) N(-)
丨 ＼
L(+) V ー C(+)
丨
D(+)
Here C is the paternal uncle of D
Question 4- Reject options (1) and (4) because in these expression B has been represented as a male. Reject option (3) because the gender of B is not defined. Now, check option (2)
N(+) ⇔ C(-)
丨 ／ |
A(-) B(-)
|
V
Question 5-
N — A(+)
丨 │
L — M(-) B
Reject option (1) because B is the cousin of M.
Reject option (2) because L is the child of N.
Reject option (3) because the gender of N is not known.
Reject option (4) because the gender of B is not known.
Question 6-
A ≤ B…. (i); B < C…. (ii) D ≥ C….. (iii)
Combining all, we get A ≤ B < C ≤ D.
Hence A < C and I follows
Again, B < D and II follows
Question 7-
K ≤ L ….(i); L < M ….(ii); M ≥ N …(iii)
From (i) and (ii), K ≤ L < M or K < M ….(iv)
Hence I does not follow.
Again, from (iv) and (iii), K and N can’t be compared. Hence II does not follow.
Question 8-
M = N …(i); N > O ….(ii); O ≥ P ….(iii)
Combining all, we get M = N > O ≥ P
Hence M > P and so I follows
Also N > P and so II does not follow
Question 9-
M > N …(i); N ≥ O …(ii); O < P …(iii)
From (i) and (ii), M > N ≥ O or O < M.
Hence I follows.
But from I and (iii) P and M can’t be compared.
Hence II does not follow.
Question 10-
M = N …(i); N > O …(ii); O < P ….(iii)
From (i) and (ii), M = N > O or O < M
Hence II follows
But from II and (iii) M and P can’t be compared. Hence I does not follow
