Directions: Study the following information carefully and answer the questions given below:
Eight persons, A, B, C, D, E, F, G and H live in a building, where the ground floor is numbered 1; floor above is numbered 2 and so on until the topmost is numbered 8. Their ages are also given which are 10, 12, 20, 22, 24, 26, 36 and 72 not necessarily in the same order. H's age is 3 times to that of C but he is not the eldest in the group. Two persons are living between H and C. E is the youngest one and lives on 2nd floor. The sum of the ages of C and E is equal to F. H lives on an odd numbered floor above E. The difference of ages of B and G is 4 times to that of C's age and B lives just above G. A is 20 years old and lives just above H. B doesn't live on the 8th floor. The number of persons living between B and D is same as the number of persons living between B and F. B lives on an even numbered floor. D lives on one of the floors above F. The one who is the eldest person in the group lives just below the person whose age is just half of the eldest person.

Directions: Study the following information carefully and answer the ...
We know that:
  • E is the youngest one and lives on 2nd floor.
  • H's age is 3 times to that of C but he is not the eldest in the group. It means H is not 72 years old and only combination left is 12 and 36 years old so C is 12 years old and H is 36 years old.
  • The sum of the age of C and E is equal to F. As C is 12 years old then E must be 10 years old and F must be 22 years old.
  • The difference of age of B and G is 4 times to that of C's age and B lives just above G. As C is 12 years old then B's and G's age difference must be 48 years and B is elder than G so B's age must be 72 years old and G's age must be 24 years old. Now D's age must be 26 years old.
  • As we know that H lives on an odd numbered floor above E and two persons are living between H and C so we get three cases-
Case 1:
Case 2:
Case 3:
Take Case 1:
  • The one who is the eldest person in the group lives just below the person whose age is just half of the eldest person. It means B is just below H, because B is the eldest and H's age is 36 years. So, this case gets rejected.
Take Case 2:
  • The one who is the eldest person in the group lives just below the person whose age is just half of the eldest person. It means B is just below H, because B is eldest and H's age is 36 years.
  • A is 20 years old and lives just above H.
  • Two persons are living between H and C.
  • The number of persons living between B and D is same as B and F. D lives one of the floors above F. we can see that this is only possible when D is above B otherwise not possible so this case gets rejected.
Take Case 3:
  • The one who is the eldest person in the group lives just below the person whose age is just half of the eldest person. It means B is just below H, because B is eldest and H's age is 36 years.
  • A is 20 years old and lives just above H.
  • Two persons are living between H and C, C can be live at 2nd or 8th but 2nd already occupied so C lives on 8th.
  • The number of persons living between B and D is same as B and F. D lives one of the floors above F. we can see that this is only possible when D is above B otherwise not possible. So D lives on 7th then F lives on 1st. last G lives on 3rd floor.
Here is the Final table:
A lives on floor 6 and C lives on floor 8. Hence C lives 2 floors above A.

Directions: Study the following information carefully and answer the ...
Understanding the Problem
To solve this problem, we need to analyze the clues provided and derive the correct arrangement of the individuals based on their ages and the floors they live on.
Key Clues Analysis
- A's Age: A is 20 years old.
- E's Position: E is the youngest (10 years old) and lives on the 2nd floor.
- H and C's Relationship: H is three times C’s age and is not the oldest. There are two persons between H and C.
- B and G's Ages: The age difference between B and G is four times C’s age, and B lives just above G.
- Floor Arrangement: H lives on an odd-numbered floor above E, and A lives just above H.
- D and F's Position: D lives above F, and the number of persons between B and D is equal to the number of persons between B and F.
- Eldest Person's Position: The oldest person (72 years) lives just below the person who is half their age (which is 36 years).
Building the Arrangement
1. Assigning Ages:
- E = 10 (youngest)
- A = 20
- H = 36 (3 times C, who is 12 years)
- B and G’s ages are derived from the age difference.
- The eldest (72) must be directly below someone aged 36.
2. Floor Arrangement:
- E is on the 2nd floor.
- H must be on the 3rd or 5th floor (odd).
- A must be above H, likely on the 4th or 6th floor.
3. Finalizing Positions:
- After filling in the floors based on the clues, we find that C lives two floors above A.
Conclusion
Thus, the statement "C lives 2 floors above A" is true, making option 'D' the correct answer. The other options do not hold true based on the derived arrangement and conditions given in the clues.
