Answers & Solutions:
1) Answer (B)
From statement 1, 2, and 7 we can gather the following information:
Now, as per statement 2 Tanya will be interviewed either on Tuesday or Thursday and Sachin will be interviewed on either Saturday or Sunday.
If Tanya is interviewed on Thursday and Sachin is interviewed on Saturday then Gayatri must be interviewed on Sunday since statement 5 says at least a one day gap is required between Mahima and Gayatri’s interview. So, Abhinav will have to be interviewed on Tuesday. [Case 1]
Similarly, If Tanya is interviewed on Thursday and Sachin is interviewed on Sunday then Gayatri must be interviewed on Saturday since statement 5 says at least a one day gap is required between Mahima and Gayatri’s interview. However, Gayatri is asked questions on Indian Bankruptcy Code (IBC) (from statement 6) while the person interviewed on Saturday is asked admin law (statement 1) so this case is not possible.
If Tanya is interviewed on Tuesday and Sachin on Sunday then Gayatri will have to be interviewed on Thursday since she is asked about IBC and not admin law.
From statement 4 we know that the ones wearing blazers must be on consecutive days apart from the weekend. Also, Digivijay does not wear a blazer (statement 1) so the ones wearing a blazer can either be on Monday and Tuesday or Thursday and Friday. From statement 3 we know that the ones carrying files are interviewed before Thursday, so on any two of the days among Monday, Tuesday and Wednesday.
Even if one of the days is Wednesday, at least one person must carry a file on Monday and Tuesday. So, the ones wearing a blazer must be on Thursday and Friday.
In Case 1, upon placing the information we get the following:

6) Answer (D)
Since, each athlete finished a race with a different position and each athlete finished in a different position in each race. So, we have the possible unordered triplets of positions that anyone of them could have:
(1,2,3), (1,2,4), (1,3,4) and (2,3,4).
From 2, C’s sum of positions is maximum i.e 9. So, C must have got (2,3,4) positions in any order.
From 6, D’s positions are (1,2,4).
From 1, 4, and 5 the table can be filled as below:
From 3, it can be concluded that A had (1,3,4) as last position in R3 for B is not possible. The table further looks like

15) Answer (B)
From the table, we can see that B is not from RPS.
Hence, option B is the correct answer.
16) Answer (B)
E lives two floors above the Businessman. A lives just above the Accountant and E lives just below the Accountant. Thus, we get the following arrangement:
The Farmer, who lives above the Scientist and below the Accountant, lives three floors above the Painter. In the above arrangement, we have denoted five floors and only three floors are left. The Farmer lives three floors above the Painter. So, there are two persons between the Farmer and the Painter. Also, the Scientist lives below the Farmer.
If we have three floors below the floor of Businessman, two of the floors will be occupied by the Painter and the Scientist and one floor will be left. Also, between the Accountant and the Businessman, one floor will be occupied by the Farmer and one floor will be empty. We know that the Doctor and the Engineer live on consecutive floors. In this case, we will not have two empty consecutive floors. So, we cannot have three floors below the Businessman.
If we have two floors below the Businessman, both will be occupied by the Painter and the Scientist. One floor must be above A’s floor. We get the following arrangement:
D is the doctor and H is the Painter. B is not the Accountant. B does not live just below or just above the H’s floor. Thus, B must be the Mechanic. G lives above C but below F. Therefore, G must be the Businessman, F must be the accountant and C must be the Scientist. We get the final arrangement as:
From the arrangement, we can see that for all the eight persons, we can find the floors on which they live.
Hence, option B is the correct answer.
17) Answer (C)
E lives two floors above the Businessman. A lives just above the Accountant and E lives just below the Accountant. Thus, we get the following arrangement:
The Farmer, who lives above the Scientist and below the Accountant, lives three floors above the Painter. In the above arrangement, we have denoted five floors and only three floors are left. The Farmer lives three floors above the Painter. So, there are two persons between the Farmer and the Painter. Also, the Scientist lives below the Farmer.
If we have three floors below the floor of Businessman, two of the floors will be occupied by the Painter and the Scientist and one floor will be left. Also, between the Accountant and the Businessman, one floor will be occupied by the Farmer and one floor will be empty. We know that the Doctor and the Engineer live on consecutive floors. In this case, we will not have two empty consecutive floors. So, we cannot have three floors below the Businessman.
If we have two floors below the Businessman, both will be occupied by the Painter and the Scientist. One floor must be above A’s floor. We get the following arrangement:
D is the doctor and H is the Painter. B is not the Accountant. B does not live just below or just above the H’s floor. Thus, B must be the Mechanic. G lives above C but below F. Therefore, G must be the Businessman, F must be the accountant and C must be the Scientist. We get the final arrangement as:
From the arrangement, we can see that four people live below E.
Hence, option C is the correct answer.
18) Answer (A)
E lives two floors above the Businessman. A lives just above the Accountant and E lives just below the Accountant. Thus, we get the following arrangement:
The Farmer, who lives above the Scientist and below the Accountant, lives three floors above the Painter. In the above arrangement, we have denoted five floors and only three floors are left. The Farmer lives three floors above the Painter. So, there are two persons between the Farmer and the Painter. Also, the Scientist lives below the Farmer.
If we have three floors below the floor of Businessman, two of the floors will be occupied by the Painter and the Scientist and one floor will be left. Also, between the Accountant and the Businessman, one floor will be occupied by the Farmer and one floor will be empty. We know that the Doctor and the Engineer live on consecutive floors. In this case, we will not have two empty consecutive floors. So, we cannot have three floors below the Businessman.
If we have two floors below the Businessman, both will be occupied by the Painter and the Scientist. One floor must be above A’s floor. We get the following arrangement:
D is the doctor and H is the Painter. B is not the Accountant. B does not live just below or just above the H’s floor. Thus, B must be the Mechanic. G lives above C but below F. Therefore, G must be the Businessman, F must be the accountant and C must be the Scientist. We get the final arrangement as:
From the arrangement, we can see that F is the Accountant.
Hence, option A is the correct answer.
19) Answer (C)
E lives two floors above the Businessman. A lives just above the Accountant and E lives just below the Accountant. Thus, we get the following arrangement:
The Farmer, who lives above the Scientist and below the Accountant, lives three floors above the Painter. In the above arrangement, we have denoted five floors and only three floors are left. The Farmer lives three floors above the Painter. So, there are two persons between the Farmer and the Painter. Also, the Scientist lives below the Farmer.
If we have three floors below the floor of Businessman, two of the floors will be occupied by the Painter and the Scientist and one floor will be left. Also, between the Accountant and the Businessman, one floor will be occupied by the Farmer and one floor will be empty. We know that the Doctor and the Engineer live on consecutive floors. In this case, we will not have two empty consecutive floors. So, we cannot have three floors below the Businessman.
If we have two floors below the Businessman, both will be occupied by the Painter and the Scientist. One floor must be above A’s floor. We get the following arrangement:
D is the doctor and H is the Painter. B is not the Accountant. B does not live just below or just above the H’s floor. Thus, B must be the Mechanic. G lives above C but below F. Therefore, G must be the Businessman, F must be the accountant and C must be the Scientist. We get the final arrangement as:
From the arrangement, we can see that the Mechanic lives between the Businessman and the Farmer.
Hence, option C is the correct answer.
20) Answer (D)
E lives two floors above the Businessman. A lives just above the Accountant and E lives just below the Accountant. Thus, we get the following arrangement:
The Farmer, who lives above the Scientist and below the Accountant, lives three floors above the Painter. In the above arrangement, we have denoted five floors and only three floors are left. The Farmer lives three floors above the Painter. So, there are two persons between the Farmer and the Painter. Also, the Scientist lives below the Farmer.
If we have three floors below the floor of Businessman, two of the floors will be occupied by the Painter and the Scientist and one floor will be left. Also, between the Accountant and the Businessman, one floor will be occupied by the Farmer and one floor will be empty. We know that the Doctor and the Engineer live on consecutive floors. In this case, we will not have two empty consecutive floors. So, we cannot have three floors below the Businessman.
If we have two floors below the Businessman, both will be occupied by the Painter and the Scientist. One floor must be above A’s floor. We get the following arrangement:
D is the doctor and H is the Painter. B is not the Accountant. B does not live just below or just above the H’s floor. Thus, B must be the Mechanic. G lives above C but below F. Therefore, G must be the Businessman, F must be the accountant and C must be the Scientist. We get the final arrangement as:
From the arrangement, we can see that E lives three floors below the Doctor.
Hence, option D is the correct answer.
