IBPS RRB PO (Scale 1) Prelims Mock Test - 8 - Question 28

Direction: Study the information given below carefully and answer the question that follows.

Eight persons A, B, C, D, E, F, G, and H are sitting around a circular table facing the center but not necessarily in the same order. The age of these people is different from each other.

Following are the conditions used to determine the age of the persons.

Arrangement 1: M@ means that the age of the person sitting to the immediate left of M is twice as that of M.

Arrangement 2: M% means that the age of M is one-fourth the age of the person who is sitting second to her left.

Arrangement 3: M# means that the age of the person sitting third to the right of M is twice as that of M.

Only one person is sitting between B and H. A is sitting to the immediate right of D who is 20 years older than E. F is 25 years older than the person who is sitting immediate right of his. B is sitting third to the right of the person who is 18 years old. The person who is 40 years old is sitting third to the right of H. E is sitting third to the left of C and E is not an immediate neighbour of H. C is not an immediate neighbour of either B or H.

It is also known that:

A#, G@, A%, B@

Who is sitting second to the left of the person who is the oldest of all?

Detailed Solution for IBPS RRB PO (Scale 1) Prelims Mock Test - 8 - Question 28
1) B is sitting third to the right of the person who is 18 years old.

As it is a circular arrangement, we can randomly pick a seat for the person who is 18 years old and then we can place B accordingly.

2) Only one person is sitting between B and H.

3) The person who is 40 years old is sitting third to the right of H.

H is sitting either second to the left of B or second to the right of B. Let us assume that H is sitting second to the right of B, then in that case the person who is 40 years old would be sitting in the same place where the 18-year-old person is sitting which is not possible. Thus, H is sitting second to the left of B and the 40-year-old person is sitting to the immediate right of B.

4) E is sitting third to the left of C and E is not an immediate neighbour of H.

5) C is not an immediate neighbour of either B or H.

There is only one way for this to be possible i.e. if C is sitting second to the left of H and E is sitting to the immediate right of B.

6) A is sitting to the immediate right of D who is 20 years older than E.

There is only one pair of two consecutive seats empty i.e. the two seats to the left of C. Thus, A is sitting to the immediate left of C and D is sitting to the immediate left of A. Also, as E is 40 years old, implies, D is 60 years old.

7) F is 25 years older than the person who is sitting immediate right of his.

Implies, F is older than 18 years and he is not sitting between C and H. Thus, G is sitting between C and H, and F is sitting between B and H. Also, let us assume the age of B to be X years then the age of F would be X + 25 years.

Now,

G@ → The person sitting to the immediate left of G is twice as old as G. C is sitting to the immediate left of G, thus, C is 36 years old.

A% → The age of A is one fourth the age of the person who is sitting second to the left of A. E is sitting second to the left of A and E is 40 years old. Thus, A is 10 years old.

A# → The age of the person who is sitting third to the right of A is twice as that of A. H is sitting third to the right of A. Thus, H is 20 years old.

B@ → The age of the person who is sitting to the immediate left of B is twice as that of B. F is sitting to the immediate left of B. Thus,

X + 25 = 2X

⇒ X = 25 years = The age of B

The age of F = 2X = 50 years

Thus, "B is sitting second to the left of D" who is the oldest of all.

IBPS RRB PO (Scale 1) Prelims Mock Test - 8 - Question 29

Direction: Study the information given below carefully and answer the question that follows.

Eight persons A, B, C, D, E, F, G, and H are sitting around a circular table facing the center but not necessarily in the same order. The age of these people is different from each other.

Following are the conditions used to determine the age of the persons.

Arrangement 1: M@ means that the age of the person sitting to the immediate left of M is twice as that of M.

Arrangement 2: M% means that the age of M is one-fourth the age of the person who is sitting second to her left.

Arrangement 3: M# means that the age of the person sitting third to the right of M is twice as that of M.

Only one person is sitting between B and H. A is sitting to the immediate right of D who is 20 years older than E. F is 25 years older than the person who is sitting immediate right of his. B is sitting third to the right of the person who is 18 years old. The person who is 40 years old is sitting third to the right of H. E is sitting third to the left of C and E is not an immediate neighbour of H. C is not an immediate neighbour of either B or H.

It is also known that:

A#, G@, A%, B@

What is the age of the person who is sitting to the immediate left of C?

Detailed Solution for IBPS RRB PO (Scale 1) Prelims Mock Test - 8 - Question 29
1) B is sitting third to the right of the person who is 18 years old.

As it is a circular arrangement, we can randomly pick a seat for the person who is 18 years old and then we can place B accordingly.

2) Only one person is sitting between B and H.

3) The person who is 40 years old is sitting third to the right of H.

H is sitting either second to the left of B or second to the right of B. Let us assume that H is sitting second to the right of B, then in that case the person who is 40 years old would be sitting in the same place where the 18-year-old person is sitting which is not possible. Thus, H is sitting second to the left of B and the 40-year-old person is sitting to the immediate right of B.

4) E is sitting third to the left of C and E is not an immediate neighbour of H.

5) C is not an immediate neighbour of either B or H.

There is only one way for this to be possible i.e. if C is sitting second to the left of H and E is sitting to the immediate right of B.

6) A is sitting to the immediate right of D who is 20 years older than E.

There is only one pair of two consecutive seats empty i.e. the two seats to the left of C. Thus, A is sitting to the immediate left of C and D is sitting to the immediate left of A. Also, as E is 40 years old, implies, D is 60 years old.

7) F is 25 years older than the person who is sitting immediate right of his.

Implies, F is older than 18 years and he is not sitting between C and H. Thus, G is sitting between C and H, and F is sitting between B and H. Also, let us assume the age of B to be X years then the age of F would be X + 25 years.

Now,

G@ → The person sitting to the immediate left of G is twice as old as G. C is sitting to the immediate left of G, thus, C is 36 years old.

A% → The age of A is one fourth the age of the person who is sitting second to the left of A. E is sitting second to the left of A and E is 40 years old. Thus, A is 10 years old.

A# → The age of the person who is sitting third to the right of A is twice as that of A. H is sitting third to the right of A. Thus, H is 20 years old.

B@ → The age of the person who is sitting to the immediate left of B is twice as that of B. F is sitting to the immediate left of B. Thus,

X + 25 = 2X

⇒ X = 25 years = The age of B

The age of F = 2X = 50 years

A is sitting to the immediate left of C and his age is "10 years".

Who is sitting third to the right of D?

Detailed Solution for IBPS RRB PO (Scale 1) Prelims Mock Test - 8 - Question 30
1) B is sitting third to the right of the person who is 18 years old.

As it is a circular arrangement, we can randomly pick a seat for the person who is 18 years old and then we can place B accordingly.

2) Only one person is sitting between B and H.

3) The person who is 40 years old is sitting third to the right of H.

There is only one way for this to be possible i.e. if C is sitting second to the left of H and E is sitting to the immediate right of B.

6) A is sitting to the immediate right of D who is 20 years older than E.

There is only one pair of two consecutive seats empty i.e. the two seats to the left of C. Thus, A is sitting to the immediate left of C and D is sitting to the immediate left of A. Also, as E is 40 years old, implies, D is 60 years old.

7) F is 25 years older than the person who is sitting immediate right of his.

Implies, F is older than 18 years and he is not sitting between C and H. Thus, G is sitting between C and H, and F is sitting between B and H. Also, let us assume the age of B to be X years then the age of F would be X + 25 years.

Now,

G@ → The person sitting to the immediate left of G is twice as old as G. C is sitting to the immediate left of G, thus, C is 36 years old.

A% → The age of A is one fourth the age of the person who is sitting second to the left of A. E is sitting second to the left of A and E is 40 years old. Thus, A is 10 years old.

A# → The age of the person who is sitting third to the right of A is twice as that of A. H is sitting third to the right of A. Thus, H is 20 years old.

B@ → The age of the person who is sitting to the immediate left of B is twice as that of B. F is sitting to the immediate left of B. Thus,

X + 25 = 2X

⇒ X = 25 years = The age of B

The age of F = 2X = 50 years

Thus, "G is sitting third to the right of D".
