33Who among P, Q, R, S and T is the lightest? Statements:I.R is heavier than Q and T but lighter than S. II.S is not the heaviest.
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:D
Explanation:
From I, we have: R>Q, R>T, S>R i.e. S>R>Q>T or S>R>T>Q.
From II, S is not the heaviest. So, P is the heaviest. Thus, we have: P > S > R > Q > T or P > S > R > T > Q. Hence, either T or Q is the lightest.
D
34How is T related to K? Statements:I.K has two sons; one of the sons is A. II.The mother of T has only two sons - Aand B.
A
I alone is sufficient while II alone is not sufficient

Correct Ans:D
Explanation:
From both I and II together, we can conclude that A and B are the children of D, but the sex of A and the third child of D is not known. So, both the statements together are also not sufficient to answer the question.
D

A
I alone is sufficient while II alone is not sufficient
B
II alone is sufficient while I alone is not sufficient

Explanation:
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.

B
II alone is sufficient while I alone is not sufficient
C
Both I and II are sufficient
D
Neither I nor II is sufficient
Correct Ans:C
Explanation:
From I and II, we find that Robert read (300 x 2/3) i.e. 200 pages before Sunday and the last 40 pages on Monday.
This means that he read [300 - (200 + 40)] i.e. 60 pages on Sunday.
C
40What will be the total weight of 10 poles each of the same weight ? Statements: 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
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
Explanation:
From I, we find that the weight of one pole is (5 x 4) = 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 or weight of one pole - 20 kg.
