Question: 1

How is B related to A?
I. A is B's sister.
II. D is the father of A and B.

(A) If the data in both the statements together are needed.

(B) If the data even in both the statements together are not sufficient to answer the question.

(C) If the data either in I or II alone are sufficient to answer the question.

(D) If the data in statement II alone are sufficient answer the question.

Ans: B

From statements I and II together, we can conclude only that either B is the sister or brother of A. So, even from both the statements, the exact relation cannot ne known.

Question: 2

What will be the total weight of 10 poles each of the same weight?
I. One fourth of the weight of a pole is 5 kilograms.
II. The total weight of three poles is 20 kilograms more than the total weight of two poles.

(A) If the data either in I or II alone are sufficient to answer the question.

(B) If the data even in both the statements together are not sufficient to answer the question.

(C) If the data in both the statements together are needed.

(D) If the data in statement I alone are sufficient to answer the question.

Ans: A

From I, we find that the weight of one pole is (5 x 4) i.e. 20 kg and so the weight of 10 poles is 200 kg. thus, I alone is sufficient.
From II, we have : (weight of 3 poles weight of 2 poles) = 20 kg
So, weight of 10 poles = 20 kg
So, weight of 10 poles = 200 kg.
Thus, II alone is also sufficient.

Question: 3

What is the birth date of Sonali's mother?
I. Sonali's father remembers that his wife's birthday is after 20th and before 23rd February.
II. Sonali's brother remembers that their mother's birthday was after 21st but before 25th February.

(A) If the data in both the statements together are needed.

(B) If the data even in both the statements together are not sufficient to answer the question.

(C) If the data either in I or II alone are sufficient to answer the question.

(D) If the data in statement I alone are sufficient to answer the question.

Ans: A

From I, we find that the birthday of Sonali's mother falls on 21st or 22nd February.
From II, we find that the birthday of Sonali's mother falls on 22nd, 23rd or 24th February.
The day common to the above two groups is 22nd February. So, the birthday falls on 22nd February.

Question: 4

Among four friends A, B, C and D, who is the heaviest?
I. B is heavier than A, but lighter than D.
II. C is lighter than B.

(A) If the data in statement I alone are sufficient to answer the question.

(B) If the data in statement II alone are sufficient answer the question.

(C) If the data even in both the statements together are not sufficient to answer the question.

(D) If the data in both the statements together are needed.

Ans: D

From I, we have A < B < D.
From II, we have C < B.
Combining (i) and (ii), we can conclude that D is the heaviest. So, both the statements are needed.

Question: 5

(A) If the data in statement I alone are sufficient to answer the question.

(B) If the data in statement II alone are sufficient answer the question.

(C) If the data either in I or II alone are sufficient to answer the question.

(D) If the data in both the statements together are needed.

Ans: D

From I, we conclude that F is the son of B.
From II, we conclude that B's wife is D's mother.
This means that D and F are the sons of B and D is the brother of F.
So, both I and II are required.
