IBPS PO Reasoning: Seating Arrangement and Blood Relations questions with solutions

Q1. In a family of seven members with two generations, all males are married. The members are X, P, Q, Y, Z, A and B. X is the brother-in-law of A. A has only two children and both are of different genders. The mother-in-law of Q is the sister of X. The mother of P is the sister-in-law of Y. P and B are of the same gender. What is the relation of P with respect to B?

1. Daughter
2. Sister-in-law
3. Mother
4. Daughter-in-law

Answer: Daughter

From the clues, A is the parent of two children of different genders, and the family has only two generations. The relations force P to be the child of B. Since P and B are of the same gender, P is B's daughter.

Q2. Who among the following is the mother of A?

1. Z
2. U
3. X
4. Y

Answer: Z

The correct answer is Z, as indicated by the relationship information in the question set. This is a direct blood-relation identification question.

Q3. In a family of 9 members — Jyotsna, Lavanya, Mahesh, Megha, Prem, Priya, Ram, Supriya, and Vijay — there are 2 married couples in the family. The following information is known: A. Prem is the son of Mahesh. B. Prem is married to Priya. C. Jyotsna is the sister of Priya. D. Lavanya is the daughter of Prem's father, Mahesh, and she is married to Ram's son, Vijay. E. Jyotsna is the aunt of both Supriya and Megha. F. Vijay has no child. Who is the paternal aunt of Megha?

1. Priya
2. Jyotsna
3. Lavanya
4. Can't be determined

Answer: Lavanya

Prem is Mahesh’s son, and Lavanya is also Mahesh’s daughter, so Lavanya is Prem’s sister. Since Megha is in Prem’s branch of the family, her paternal aunt is the sister of her father, i.e. Lavanya. Hence, Lavanya is the correct answer.

Q4. Seven persons A, B, C, M, N, O and P are sitting in a row facing north, not necessarily in the same order. - N sits third from an extreme end. - C sits immediately to the right of P. - Only one person sits between P and M. - P sits second to the left of N. - B is not an immediate neighbor of N and A. - The number of persons to the right of A is the same as the number of persons to the left of O. Who sits third to the right of M?

1. P
2. N
3. C
4. O

Answer: C

N must be at position 3 or 5. Since P is second to the left of N, the valid placement gives P and then C immediately to its right. Using the one-person gap between P and M fixes M, and counting three places to the right of M gives C.

Q5. Study the following arrangement: C D B A R ← > L ABCD ी > R PQRS । ← R S P Q How many times does the letter 'R' appear in the entire arrangement?

1. 2
2. 3
3. 4
4. 5

Answer: 5

The arrangement contains multiple occurrences of the letter R in different parts of the string. Counting each visible R in the full arrangement gives a total of 5. Hence, the correct answer is 5.

Q6. Study the following information carefully and answer the question given below: Eight persons namely J, K, L, M, N, O, P and Q are living in an eight-floor building with the bottommost floor being the first floor and the topmost floor being the eighth floor. Only one person stays on one floor. All of them belong to the same family and there are only two married couples, but they have different blood groups, i.e. AB+, AB-, O-, B-, A+, O+ and B+. Each of them participated and obtained different grades in a competitive exam, viz. A, B, C, D, E, F, G and H, but not necessarily in the same order. The grading is done in alphabetical order on the basis of marks, with the top scorer obtaining A grade and the lowest scorer being given H grade. L's maternal aunt does not live on the eighth or first floor. The person who is the third lowest scorer lives on the fifth floor. K is the wife of Q and she has only one child. The person who scored sixth highest marks does not have B- blood group. The person whose blood group is AB- lives on an even-numbered floor. The person whose blood group is O- is an unmarried brother of Q. O is the sister-in-law of Q. L's grandmother has only one brother. The person whose blood group is AB+ lives on the top floor. The third highest scorer lives between K and L's grandmother. O obtained B grade and M's husband's brother-in-law scored the highest marks. M is the mother of Q. The person who obtained G grade has O- blood group and does not stay on the fifth floor. The person whose blood group is A+ lives on the seventh floor. N is the father of J, who is the uncle of L. K's father-in-law obtained E grade and lives on the sixth floor. The person who obtained D grade has A- blood group and lives on the third floor. The person who scored the lowest marks lives on the first floor. Q's child and the one whose blood group is B+ live on an even-numbered floor. L's grandmother obtained F grade and L's uncle is the second lowest scorer. L does not have AB- blood group. Q48. Who amongst the following lives on an even-numbered floor below the person whose blood group is O+?

1. Q
2. The one whose blood group is A-
3. The one who obtained F grade
4. The one who obtained C grade

Answer: The one who obtained F grade

This is a multi-constraint floor arrangement involving family relations, blood groups, and grades. After placing the fixed clues, the person with O+ blood group is determined, and the only person who fits the condition of living on an even-numbered floor below that person is the one who obtained F grade. Hence, that option is correct.

Q7. There are seven members in a family across three generations, namely Kavish, Lavanya, Mahipal, Prinshu, Ritika, Tanveer, and Ushu, in which there are 3 married couples. Kavish has only two children. Ushu is the unmarried sister-in-law of Ritika. Tanveer is the only son of Prinshu. Lavanya is the wife of Mahipal. Kavish is the paternal grandfather of Mahipal. Both Kavish and Prinshu are in the same generation. How many persons are there in the youngest generation?

1. One
2. Two
3. Three
4. Data inadequate

Answer: Two

Kavish is the paternal grandfather of Mahipal, so Kavish belongs to the oldest generation and Mahipal to the youngest or middle depending on parents. Since Kavish has only two children and there are 3 married couples among 7 people, the family structure fits with two people in the youngest generation. Thus, the youngest generation has two persons.

Q8. Study the given information carefully and answer the following question. Nine people A, B, C, D, E, F, G, H, and J are living on different floors of a building, not necessarily in the same order, such that four floors remain vacant. The ground floor is numbered 1, the first floor is numbered 2, and so on. The top and bottom floors of the building are vacant. There are four floors between A and G. A lives above G. Two persons live between the floors on which H and D live. A lives immediately below H. G is not living on an odd-numbered floor. G lives immediately above a vacant floor. The number of floors between the floors on which C and J live is the same as the number of floors between the floors on which G and B live. C lives on a floor above J and G. D lives immediately below a vacant floor. No two vacant floors are immediate neighbours. At most three floors are there between two vacant floors. The difference between the floors on which F and E live is a prime number, with F living above E. Four among the five are the same and thus form a group. Who among the following does not belong to that group?

1. H
2. C
3. G
4. A

Answer: H

This is a floor arrangement puzzle with multiple constraints. Solving the positions of the people and vacant floors shows that three of the options fit the same positional pattern, while H differs from them. Hence, H does not belong to the group.

Q9. Number of persons sitting to the right of C is one less than the number of persons sitting to the left of __. 1. The one who sits immediate right of D. 2. A 3. G 4. The one who sits immediate left of F. 5. E Who among the following satisfies the condition?

1. The one who sits immediate right of D.
2. A
3. G
4. The one who sits immediate left of F.

Answer: G

This is a seating arrangement comparison question. After placing the persons according to the given conditions, the person whose left-side count is one more than C's right-side count is G. Therefore, G satisfies the condition.
