Consider the Question and two Statements given below:
Question: Is Z brother of X?
Statement-1: X is a brother of Y and Y is a brother of Z.
Statement-2: X, Y and Z are siblings.
Which one of the following is correct in respect of the Question and the Statements?
Statement 1: Gender of Z is unknown, so Z can be brother or sister of X. Thus this statement alone is not sufficient to answer the question.
Statement 2: X, Y and Z are siblings. Gender of X, Y and Z is not clear in the statement. So they all can be brothers or they all can be sisters or one brother two sisters etc. This this statement alone is also not sufficient to answer the question.
Even combining both the statements will not give any useful information to get a clear answer. Thus answer is d.

Q 19. Blood Relations
A family of two generations consists of six members P, Q, R, S, T and U with three males and three females. There are two married couples and two unmarried siblings. U is the daughter of P and Q is the mother-in-law of R. T is an unmarried male and S is a male. Which one of the following is correct?
There are 6 members – 3 males (T, S and one other) and 3 females (U, Q and one more). We do not know about the gender of P and R.
There are two couples and rest of the two are unmarried siblings. These are definitely married – P, Q, R. These are definitely single – T. We do not know whether S and U are married or not.
As U is P’s daughter and Q is R’s mother-in-law, it means that P and Q belong to the senior generation and U and R belong to the junior generation.
+ is male, - is female.
U and T are the unmarried siblings. R is S’s wife. Hence option (b) is the correct answer.
Q 71. Blood Relations
A joint family consists of seven members A, B, C, D, E, F and G with three females. G is a widow and sister-in-law of D's father F. B and D are siblings and A is daughter of B. C is cousin of B. Who is E?
1. Wife of F
2. Grandmother of A
3. Aunt of C
Select the correct answer using the code given below:
● Identifying Relationships:
○ G is a widow and sister-in-law of D's father F. This implies G was married to F's brother.
○ B and D are siblings, so they share the same parents.
○ A is the daughter of B, making B one of A's parents.
○ C is a cousin of B, meaning C is the child of B's uncle or aunt.
● Determining the Gender:
○ There are three females in the family: G, A, and one more.
○ G is a widow, so she is female.
○ A is the daughter of B, so she is female.
○ The third female must be either B or E.
● Analyzing the Options:
● Option 1: Wife of F
○ Since B and D are siblings and A is the daughter of B, B is likely male (father of A), making E the wife of F.
● Option 2: Grandmother of A
○ If E is the wife of F, and B is the parent of A, then E is the grandmother of A.
● Option 3: Aunt of C
○ Since C is a cousin of B, E could be the aunt of C if she is married to F, who is C's uncle.
● Conclusion:
○ E fits all three roles: the wife of F, the grandmother of A, and the aunt of C. Therefore, all three statements are correct, making the correct answer Option D: 1, 2 and 3.

Q 65. Blood Relations
Consider the following relationships among members of a family of six persons A, B, C, D, E and F:
1. The number of males equals that of females.
2. A and E are sons of F.
3. D is the mother of two, one boy and one girl.
4. B is the son of A.
5. There is only one married couple in the family at present.
Which one of the following inferences can be drawn from the above?
● Statement 1: The number of males equals that of females.
This implies there are 3 males and 3 females in the family.
● Statement 2: A and E are sons of F.
This indicates that A and E are males, and F is their parent.
● Statement 3: D is the mother of two, one boy and one girl.
This means D is a female and has one son and one daughter.
● Statement 4: B is the son of A.
This implies B is a male and A is his parent.
● Statement 5: There is only one married couple in the family at present.
This suggests that among the six members, only one pair is married.
Analysis:
○ From Statement 2, A and E are sons of F, so F is their parent. Since A is a male, F must be the other parent of A and E.
○ From Statement 3, D is the mother of two children, one boy and one girl. Since A and E are both males, D cannot be their mother. Therefore, D must be the mother of B and another female child.
○ From Statement 4, B is the son of A, which means A is male.
○ Since there is only one married couple, and D is the mother of B, A must be the husband of D to form the only married couple.
Therefore, the inference that can be drawn is that A is the husband of D.

○ From statement 2: *C is the father of A*. This implies C is also the father of B, since A and B are siblings.
○ From statement 3: *D is the brother of E*. This means D and E are siblings.
○ From statement 4: *E is the daughter of B*. This indicates that B is the parent of E, and consequently, the parent of D as well.
Now, we need to determine the uncle of D:
○ Since B is the parent of D, B's brother would be D's uncle.
○ From statement 1, we know that A is the brother of B.
○ Therefore, A is the uncle of D.
Hence, the correct answer is Option A: A.
