LOGIC REASONING

1) Ans:- (a)

Solution:

STATEMENT I: Rs sister is mother of N, who is daughter of S.

Let X be Rs sister.

R Sister X S

Mother

Daughter of

N

X is sister of R. N is child of X and daughter of N. Therefore, X

has to be mother and S has to be father of N.

STATEMENT II: P is the sister of S.

P sister S

To find how S is related to R, data in statement I alone is

sufficient. S is related to R as brother in law.

But data provided in statement II alone is not sufficient to tell

how S is related to R.

Hence, option (a): data in statement I alone are to sufficient to

answer the question, while the data in statement II alone are not

sufficient to answer the question.

2) Ans:- (a)

Solution:

Given A#B$C*D

i) Here, A#B means A is mother of B. Therefore, B is child of A.

ii) Further, B$C means B is brother of C.

iii) C*D means C is daughter of D.

Hence, from (i) and (ii)B and C are siblings and children of A.

From (iii) C is daughter of D.

Therefore, as A is mother of C, D has to be the father.

Hence, in A#B$C*D D is the father.

The correct answer is option (a) D.

3) Ans:- (c)

Solution:

P, Q, R, S and T teach five courses A, B, C, D and E from

January to May.

According to given data, P teaches course B and Q teaches

course A.R does not teach course C or D. Therefore, R

teaches course E, since course A and B are already being

taught by Q and P respectively.

Therefore, lecturer S will be teaching either course C or D.

Hence, correct answer is option (c)either C or D.

4) Ans:- (3)

A B

Pens can be position A or B.

In position A, only condition IV is right.

In position B, conditions I, II and IV are true.

From above results, we conclude that only condition IV is true.

Hence, correct answer is option (3)Only IV follows.

5) Ans:- (3)

Solution:

We will first arrange all words and numbers in descending order . Now we will alternately place Words and numbers in descending order, keep remaining sentence same. Hence, output will be as follows:

For Given Input Input: glass full 15 37 water now 85 67 Descending words: water, now, glass, full Descending numbers: 85,67,37,15 Step I: water glass full 15 37 now 85 67 Step II: water 85 glass full 15 37 now 67

Step III: water 85 now glass full 15 37 67 Step IV: water 85 now 67 glass full 15 37 Step V: water 85now 67 glass full 15 37 Step VI: water 85now 67 glass 37 full 15 Correct answer is option (3)
