Blood Relations: SSC CGL Practice Questions

Ans: A

Explanation: Let’s break down the relationships step by step:

1. **U is T’s mother:** This establishes a mother-child relationship between U and T.
2. **T’s brother is married to P:** This means P is the spouse of T’s brother. So, P and T share the same brother.
3. **Q is the daughter of S and P:** This tells us S is the spouse of P, making S the father or mother of Q.
4. **Q is also the granddaughter of R:** This means R is either the parent of S (if S is the parent of Q) or the parent of P (if P is the parent of Q). Since Q is the daughter of S and P (and thus their only child), R is a grandparent. Because U is T’s mother and Q’s other parent (either S or P) is also related to T, then R must be the parent of the parents of Q, which is also the parent or parent of T. This means R must be the spouse of U.

Since U is T’s mother, and R is the spouse of U, therefore R is T’s father.

Correct Option: A

Ans: A

Explanation: A is the mother of B, and B is the sister of C. Therefore, A is also the mother of C. C is married to D, making D the spouse of A’s child (C). E is the son of D, meaning E is the grandchild of A. Therefore, A is the grandmother of E.

Ans: D

Explanation: Let’s break down the relationships:
* Arya is the daughter of Rohan.
* Kiran is the brother of Rohan.
* Maya is the mother of Rohan (and Kiran, as they are siblings).
* Shreya is the wife of Kiran.
* Dhruv is the son of Shreya (and Kiran).
* Gaurav is the father of Tanya.
* Arya and Tanya are cousins. This confirms that Rohan and Kiran are siblings.

Since Maya is the mother of Kiran, and Kiran is Dhruv’s father, Maya is Dhruv’s grandmother.

Ans: A

Explanation: Let’s break down the relationships step by step:

* W @ S: W is the brother of S.
* S % K: S is the son of K.
* K $ G: K is the husband of G (meaning G is K’s wife).
* G & U: G is the mother of U.
* U & T: U is the mother of T.
* T @ R: T is the brother of R.
* R + C: R is the daughter of C.

Now let’s trace the family tree:
* G is married to K and is the mother of U.
* U is the mother of T and T is the brother of R.
* R is the daughter of C.
* Since G is the mother of U, and U is the mother of T (brother of R) and R is the daughter of C, this means G is the maternal grandmother of R, and C is the father of R and husband of U.

Let’s look at the options:

* A. G is the maternal grandmother of R. – This is correct.
* B. G is the father of W. – G is female and the maternal grandmother of R. W’s relation is ambiguous, but can’t be son.
* C. C is the wife of U. – C is the father of R, R is daughter of C, and C is married to U.
* D. C is the father-in-law of K. – G is the wife of K and U is the mother of T. K has no explicit relation to C.

Correct Option: A

Ans: C

Explanation: Let’s break down the expression: H > R $ S @ T > N.

1. **H > R:** H is the daughter of R.
2. **R $ S:** R is the father of S.
3. **S @ T:** S is the son of T.
4. **T > N:** T is the daughter of N.

Combining these:

* H is the daughter of R.
* R is the father of S. Therefore, S is the sibling of H. S is a son (S @ T) and the sibling of H.
* S is the son of T.
* T is the daughter of N. Since S is the son of T and T is the daughter of N, S is the grandson of N.

Correct Option: C

Ans: B

Explanation: Let’s break down the expression ‘X * Y $ Z’.
* ‘X * Y’ means X is the father of Y.
* ‘Y $ Z’ means Y is the daughter of Z.
Combining these, we know X is the father of Y and Y is the daughter of Z. This implies that X is the father of Y and Y is the mother or father (depending on Z’s gender) of Z. Therefore X must be the father of Y, and Y is a parent of Z, which means X is the paternal grandfather of Z.

Ans: B

Explanation: Let’s break this down:

* “J is the paternal grandmother of K” means J is K’s father’s mother.
* “P is the father of K” confirms P is K’s father, and J is P’s mother.
* “O is the mother-in-law of P” means O is married to P’s father/J’s husband.
* “L is the daughter of M, who is the sister of N”. This is where the relation between N and K is. Since K’s father is P, and O is his mother-in-law, O is married to J’s husband/P’s father. Thus, M and N are the children of J. Therefore, M and N are siblings of P. Since N is a sibling of P (K’s father), N is K’s aunt.

Ans: A

Explanation: Let’s break down the statement: “His mother is the only daughter of my mother’s father.”
* “My mother’s father” is Priya’s grandfather.
* “The only daughter of my mother’s father” is Priya’s mother (because her grandfather only has one daughter, who is Priya’s mother).
* Therefore, the man’s mother is Priya’s mother.
* If the man’s mother is Priya’s mother, then Priya and the man are siblings.

Ans: C

Explanation: Let’s break down the statement: “His mother is the only daughter of my mother’s mother.”

* “My mother’s mother” refers to Priya’s maternal grandmother.
* “The only daughter of my mother’s mother” means the only daughter of Priya’s maternal grandmother, which is Priya’s mother.
* The statement is essentially saying that the man’s mother is Priya’s mother. Therefore, Priya and the man are siblings.

Ans: D

Explanation: Priya’s mother’s only brother is her uncle. The man is the son of Priya’s uncle, which makes him her cousin.

Ans: A

Explanation: The question seems to have conflicting information, as Priya and Soni are both daughters of Rajesh, and Deepak is the father of Soni. This implies that Rajesh and Deepak are the same person. Also, Rohan is the brother of Priya. Therefore, Deepak (or Rajesh) is the father of Rohan.

Ans: C

Explanation: The question describes a family tree. Rohan is Priya’s son, and Priya is Ajay’s sister. This means Ajay is Rohan’s uncle. Ajay’s mother is Meena, making Meena Rohan’s grandmother. Therefore, Rohan is Meena’s grandson.

Ans: B

Explanation: Rohan’s grandfather’s only son is Rohan’s father. Therefore, the girl is the daughter of Rohan’s father, making her Rohan’s sister.

Ans: D

Explanation:
1. **R2S means R is the wife of S.** Therefore, if R is the wife of S, then S is the husband of R.
2. To represent X being the mother of Y, we need to find X’s husband and then show that husband is the father of Y.
3. Let M be the husband of X. So, X2M (X is the wife of M).
4. M8Y (M is the father of Y).
5. Combining these, the expression is X2M8Y, but the codes are arranged in the reverse direction. So we must arrange them in the correct way.
6. The correct arrangement would be X2M8Y. However, this option is not available.
7. Let’s analyze the other options.
* **A. X8M2Y**: This implies X is the father of M, M is the wife of Y. This is incorrect.
* **B. X7M6O2Y**: X is the sister of M, M is the brother of O, O is the wife of Y. This is incorrect.
* **C. X2M8O2Y**: X is the wife of M, M is the father of O, O is the wife of Y. This is also a possible answer. If O is Y, it is correct.
* **D. X2M8Y**: X is the wife of M, and M is the father of Y. This is also a possible answer.

Since option C and D seem to be most plausible answer, let’s explore if there’s any other hidden clues. Based on the fact the provided options are for a banking exam, and the question is asking to identify a mother-child relationship, the most likely interpretation of the code would be in direct relationship between X and Y.

Let’s rearrange the format of relationship, from the perspective of X and Y.
X2M means X is the wife of M, or M is the husband of X
M8Y means M is the father of Y. Combining these gives X’s husband is the father of Y, hence X is the mother of Y.
Now let us check each option.
A. X8M2Y This is not a direct relationship
B. X7M6O2Y This is not a direct relationship
C. X2M8O2Y is also a valid interpretation, if O and Y are same, i.e., O=Y
D. X2M8Y X is wife of M, M is father of Y.

Hence we see that options C and D are most plausible answer. However, from the original explanation, X2M8Y would be most appropriate.

Correct Option: D
