BLOOD RELATION
Both the women are shorter than their respective husbands.
A is the tallest among the four.
C is taller than B.
D is B's brother.
In this context, which one of the following statements is not correct? (2015)
(a)All four have family ties.
(b) B is the shortest among the four.
(c) C is taller than D.
(d) A is B's husband.
Answer: C
A is the tallest, so A must be male.
D is B's brother, so D must also be male.
Since A and D are male, B and C must be female.
Based on this information, we can conclude that D is the husband of C, and D is shorter than A but taller than B.
Therefore, the statement (c) "C is taller than D" is incorrect. It should be the other way around: D is taller than C.
A + B means A is the son of B.
A - B means A is the wife of B.
What does the expression P + R- Q mean?(2017)
(a) Q is the son of P.
(b) Q is the wife of P.
(c) Q is the father of P.
(d) None of the above
Answer: C
The correct answer is (c), Q is the father of P.
We know that A+B means A is the son of B, and A-B means A is the wife of B. Therefore, P+R means P is the son of R, and R-Q means R is the wife of Q. Combining these two statements, we can conclude that P is the son of R, and R is the wife of Q. This means that Q is the father of P.
A, B, C, D, E and F:
- The number of males equals that of females.
- A and E are sons of F.
- D is the mother of two, one boy and one girl.
- B is the son of A.
- There is only one married couple in the family at present.
Which one of the following inferences can be drawn from the above?(2017)
(a) A, B and C are all females.
(b) A is the husband of D.
(c) E and F are children of D.
(d) D is the daughter of F.
Answer: B
We know that there are three males and three females in the family. A and E are sons of F, so F must be male. D is the mother of two, one boy and one girl, so D must be female. B is the son of A, so A must be male. There is only one married couple in the family, so A and D must be married. Therefore, A is the husband of D.
(a) A, B, and C are all females. This is not possible, because we know that A and E are sons of F, so A and E must be male.
(c) E and F are children of D. This is not possible, because we know that A and E are sons of F, so F must be the parent of A and E.
(d) D is the daughter of F. This is not possible, because we know that D is the mother of two, one boy and one girl, so D must be an adult.
Select the correct answer using the code given below:
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer: D
E is the wife of F, the grandmother of A, and the aunt of C.
(a) R is U's husband.
(b) R is S's wife.
(c) S is unmarried.
(d) None of the above
Answer: B
We know that there are three males and three females in the family. U is P's daughter, so U is female. Q is R's mother-in-law, so R is married and Q is female. T is an unmarried male, so T is male. S is a male.
There are two married couples and two unmarried siblings. This means that either P and Q or R and S are married, and the other two are siblings. We also know that U is P's daughter, so U is either Q's daughter or R's daughter.
Putting all this information together, we can deduce that P and Q are married, since U is their daughter. This also means that R and S are married, since they are the remaining couple. Therefore, R is S's wife.
(a) R is U's husband. This is not possible, because we know that U is P's daughter, so U is female.
(c) S is unmarried. This is not possible, because we know that there are two married couples and two unmarried siblings, and S is not one of the unmarried siblings.
(d) None of the above. This is not possible, because we know that R is S's wife.
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?(2022)
(a) Statement-1 alone is sufficient to answer the Question
(b) Statement-2 alone is sufficient to answer the Question
(c) Both Statement-1 and Statement-2 are sufficient to answer the Question
(d) Both Statement-1 and Statement-2 are not sufficient to answer the Question
Answer: D
From the given question, we need to determine if Z is the brother of X. Let's evaluate the given statements:
Statement-1: X is a brother of Y and Y is a brother of Z.
This statement implies that X, Y, and Z are siblings. However, we do not know the gender of X, Y, or Z, and we cannot determine if Z is a brother of X from this statement alone.
Statement-2: X, Y and Z are siblings.
This statement confirms that X, Y, and Z are siblings. However, we do not know their gender or the relationship between them. We cannot determine if Z is a brother of X from this statement alone.
Combining both statements, we know that X, Y, and Z are siblings. From Statement-1, we know that Y is a brother of Z, but we don't know the gender of X. Therefore, we cannot conclusively determine if Z is a brother of X.
Since neither statement alone is sufficient to answer the question, and even when taken together, we cannot give a definitive answer, the correct answer is (d) Both Statement-1 and Statement-2 are not sufficient to answer the Question.
(a) Q is the grandfather of T
(b) Q is the grandmother of T
(c)R is the mother of P
(d) T is the granddaughter of Q
Answer: D
We know that R is the spouse of Q, so R is either Q's husband or Q's wife. We also know that U is the mother of T and S is the daughter of U, so U is female. P's daughter is T and R's son is P, so P is male. There are two couples in the family, so R and Q are one couple, and U and someone else are the other couple.
Putting all this information together, we can deduce that R is Q's husband, since R is male and Q is female. This also means that U is the wife of someone else, since U is female and there are only two couples in the family. Therefore, T is the granddaughter of Q, since T is the daughter of P, who is the son of R and Q.
