(B) If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
(C) If the data either in statement I alone or in statement II alone are sufficient to answer the question
(D1) If the data given in both statements I and II together are not sufficient to answer the question and
(D2) If the data in both statements I and II together are necessary to answer the question.
11How many visitors saw the exhibition yesterday ? Statements: I. Each entry pass holder can take up to three persons with him/her.

D
12Among five friends who is the tallest ? Statements: I. D is taller than A and C.
II. B is shorter than E but taller than D.
A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient;
D
Both I and II are sufficient
Correct Ans:D
Explanation:
From I, we have : D > A , D> C,
From II, we have : E >B > D.
Combining the above two, we get : E > B> D> (A and C).
So, E is the tallest.
Clearly, both the statements are needed to answer the question
D
13Madan is elder than Kamal and Sharad is younger than Arvind. Who among them is the youngest ? Statements: I.Sharad is younger than Madan. II.Arvind is younger than Kamal.
A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient
D
Neither I nor II is sufficient
Correct Ans:Z
Explanation:
As given, we have: M > K, A > S.
From II, K > A. Thus, we have: M > K > A > S.
So, Sharad is the youngest. From I, M > S. Thus, we have: M>K>A>S or M>A>K>S or M>A>S>K.
Z
14How is Sulekha related to Nandini ? Statements: I.Sulekha's husband is the only son of Nandini's mother. II.Sulekha's brother and Nandini's husband are cousins.
A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient
D
Neither I nor II is sufficient
Correct Ans:Z
Explanation:
From I, we conclude that Sulekha is the wife of Nandini's mother's only son i.e. Nandini's brother. Thus, Sulekha is Nandini's sister-in-law.
From II, we conclude that Sulekha is the cousin of Nandini's husband, which implies that Sulekha is Nandini's sister-in-law.
Z
15What is Gagan's age ? Statements: I.Gagan, Vimal and Kunal are all of the same age. II.Total age of Vimal, Kunal and Anil is 32 years and Anil is as old as Vimal and Kunal together.
A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient
D
Neither I nor II is sufficient
Correct Ans:Z
Explanation:
As given in I and II, we have: G = V = K, V + K + A = 32 and A = V + K.
Putting V + K = A in V + K + A = 32, we have: 2A = 32 or A = 16.
Thus, V + K = 16 and V = K. So, V = K = 8. Thus, G = 8.
Z
16In which year was Rahul born ? Statements: I. Rahul at present is 25 years younger to his mother. II.Rahul's brother, who was born in 1964, is 35 years younger to his mother.

B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient
D
Neither I nor II is sufficient
Correct Ans:Z
Explanation:
From both I and II, we find that Rahul is (35 - 25) = 10 years older than his brother, who was born in 1964. So, Rahul was born in 1954.
Z

A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient
C
Either I or II is sufficient;
D
Neither I nor II is sufficient
Correct Ans:C
