6) Answer (A)
We know that Ila came in just after the IAS and just before the Doctor and that the Doctor came in last. Hence, the order is A-B-C-IAS – Ila – Doctor. From 4, Mum – B – C – IAS- Ila-Doctor. Seema, a lawyer reached just before dentist. As she is not from Mumbai, she could not have reached first. The only space available then for Lawyer – Dentist is B-C. Hence, Mumbai – Seema(Lawyer) – Dentist – IAS – Ila – Doctor. Now Aarti came in just after Janaki. The only place for them to be together is if Janaki is the Dentist and Aarti is IAS. Hence, we have Mum – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS) – Ila – Doctor. Thus, the profession of the person who arrived third is Dentist.
7) Answer (C)
We know that Ila came in just after the IAS and just before the Doctor and that the Doctor came in last. Hence, the order is A-B-C-IAS – Ila – Doctor. From 4, Mum – B – C – IAS- Ila-Doctor. Seema, a lawyer reached just before dentist. As she is not from Mumbai, she could not have reached first. The only space available then for Lawyer – Dentist is B-C. Hence, Mumbai – Seema(Lawyer) – Dentist – IAS – Ila – Doctor. Now Aarti came in just after Janaki. The only place for them to be together is if Janaki is the Dentist and Aarti is IAS. Hence, we have Mum – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS) – Ila – Doctor. From 5, Divya must be the doctor who arrived last. That means Gayatri arrived first and is from Mumbai. Hence, Gayatri(Mumbai) – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS, Pune) – Ila – Divya(Doctor,Chennai). Hence, we know the professions of Seema, Janaki, Aarti and Divya. Hence, option C.
8) Answer (B)
We know that Ila came in just after the IAS and just before the Doctor and that the Doctor came in last. Hence, the order is A-B-C-IAS – Ila – Doctor. From 4, Mum – B – C – IAS- Ila-Doctor. Seema, a lawyer reached just before dentist. As she is not from Mumbai, she could not have reached first. The only space available then for Lawyer – Dentist is B-C. Hence, Mumbai – Seema(Lawyer) – Dentist – IAS – Ila – Doctor. Now Aarti came in just after Janaki. The only place for them to be together is if Janaki is the Dentist and Aarti is IAS. Hence, we have Mum – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS) – Ila – Doctor. From 5, Divya must be the doctor who arrived last. That means Gayatri arrived first and is from Mumbai. Hence, Gayatri(Mumbai) – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS, Pune) – Ila – Divya(Doctor,Chennai).
Thus, we know the location of Gayatri, Aarti and Divya. Hence, option B.
9) Answer (D)
We know that Ila came in just after the IAS and just before the Doctor and that the Doctor came in last. Hence, the order is A-B-C-IAS – Ila – Doctor. From 4, Mum – B – C – IAS- Ila-Doctor. Seema, a lawyer reached just before dentist. As she is not from Mumbai, she could not have reached first. The only space available then for Lawyer – Dentist is B-C. Hence, Mumbai – Seema(Lawyer) – Dentist – IAS – Ila – Doctor. Now Aarti came in just after Janaki. The only place for them to be together is if Janaki is the Dentist and Aarti is IAS. Hence, we have Mum – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS) – Ila – Doctor. From 5, Divya must be the doctor who arrived last. That means Gayatri arrived first and is from Mumbai. Hence, Gayatri(Mumbai) – Seema(Lawyer) – Janaki(Dentist) – Aarti(IAS, Pune) – Ila – Divya(Doctor,Chennai).
If Ila is an Interior Designer then Gayatri must be the Engineer.
10) Answer (C)
Three cities and 2 professions have not been assigned. If Ila is not from Hyderabad, the number of combinations of person – place is 3!-2 = 4. The number of combinations of person – profession is 2. Hence, the total number of combinations are 2*4 = 8.

Dhoni is taller than Dravid, who is taller than Kumble, who in turn is taller than Sehwag. So Dhoni is #4, Dravid is #5, Kumble is #6 and Sehwag is #7. Since Sehwag played Cricket and Kabaddi, Ishant played Tennis and Kabaddi. Kumble played Tennis and Srinath played Cricket. Since two guys played Table-Tennis, the sport played by Dravid and Dhoni is Table-Tennis.
The arrangement is as follows:
Sachin – Tennis, Cricket – #8

Since Sehwag played Cricket and Kabaddi, Ishant played Tennis and Kabaddi. Kumble played Tennis and Srinath played Cricket. Since two guys played Table-Tennis, the sport played by Dravid and Dhoni is Table-Tennis.

Dhoni is taller than Dravid, who is taller than Kumble, who in turn is taller than Sehwag. So Dhoni is #4, Dravid is #5, Kumble is #6 and Sehwag is #7. Since Sehwag played Cricket and Kabaddi, Ishant played Tennis and Kabaddi. Kumble played Tennis and Srinath played Cricket. Since two guys played Table-Tennis, the sport played by Dravid and Dhoni is Table-Tennis.

16) Answer (C)
From c and d we know that the Accounts dept is in the middle on the lower floor with admin on the left and Kulkarni on the right. Hence from b and f, Mukherjee is in the top left corner and the head clerk of Archives department. The technical dept is in top middle office. From a, we know that Clearance must be on the bottom floor and hence is Mr Kulkarni’s office on the right which is the only remaining office. Thus, Mr Mehra is in the top right corner. The only column where both names are missing is the middle column. Hence, Mr Jain and Mr Sharma’s offices must be in the middle column. Hence, Mr Jain is in charge of the Technical Dept and Mr Sharma is in charge of the Accounts department. This leaves Mr Verma who must be in charge of the Admin office in the bottom left corner. Hence, Mr Mehra must be in charge of the Main office.

From a, we know that Clearance must be on the bottom floor and hence is Mr Kulkarni’s office on the right which is the only remaining office. Thus, Mr Mehra is in the top right corner. The only column where both names are missing is the middle column. Hence, Mr Jain and Mr Sharma’s offices must be in the middle column. Hence, Mr Jain is in charge of the Technical Dept and Mr Sharma is in charge of the Accounts department. This leaves Mr Verma who must be in charge of the Admin office in the bottom left corner. Hence, Mr Mehra must be in charge of the Main office. Hence, Mr Mehra’s office is not adjacent.

21) Answer (B)
From the given information,
d+e+f+g = 42
a+b+c+d+e+f+g = 84
g = c – 4
d+e+f = 30
c = 2e
b+e = a-2
Solving these equations, we get, a=18, b=8, c=16, e=8, g=12 and d+f = 22
Since Football team has the maximum number of students,
a+b+d+e >= 43 => d >= 9 and
a+b+d+e >= b+c+e+f+1
=> d >= f-1
d+f = 22.
Therefore, min. value of d = 11, in which case f = 11.
22) Answer (B)
From the given information,
d+e+f+g = 42
a+b+c+d+e+f+g = 84
g = c – 4
d+e+f = 30
c = 2e
b+e = a-2
Solving these equations, we get, a=18, b=8, c=16, e=8, g=12 and d+f = 22
Since Football team has the maximum number of students, a+b+d+e >= 43 => d >= 9
and a+b+d+e >= b+c+e+f+1
=> d >= f-1
d+f = 22.
Therefore, min. value of d = 11, in which case f = 11.
The number of students in Hockey team = 32+f. f can be 0. Therefore, the minimum number of students = 32.
23) Answer (D)
From the given information,
d+e+f+g = 42
a+b+c+d+e+f+g = 84
g = c – 4
d+e+f = 30
c = 2e
b+e = a-2
Solving these equations, we get, a=18, b=8, c=16, e=8, g=12 and d+f = 22
Since Football team has the maximum number of students, a+b+d+e >= 43
=> d >= 9
and a+b+d+e >= b+c+e+f+1
=> d >= f-1
d+f = 22.
Therefore, min. value of d = 11, in which case f = 11.
Information in a), b) and c) is already known. d) is required.
24) Answer (A)
From the given information,
d+e+f+g = 42
a+b+c+d+e+f+g = 84
g = c – 4
d+e+f = 30
c = 2e
b+e = a-2
Solving these equations, we get, a=18, b=8, c=16, e=8, g=12 and d+f = 22
Since Football team has the maximum number of students, a+b+d+e >= 43
=> d >= 9 and a+b+d+e >= b+c+e+f+1
=> d >= f-1
d+f = 22.
Therefore, min. value of d = 11, in which case f = 11.
When d is minimum, value of f = 11 and d = 11. Difference = 0.
25) Answer (D)
From the given information,
d+e+f+g = 42
a+b+c+d+e+f+g = 84
g = c – 4
d+e+f = 30
c = 2e
b+e = a-2
Solving these equations, we get, a=18, b=8, c=16, e=8, g=12 and d+f = 22
Since Football team has the maximum number of students,
a+b+d+e >= 43 => d >= 9
and a+b+d+e >= b+c+e+f+1
=> d >= f-1
d+f = 22.
Therefore, min. value of d = 11, in which case f = 11.
After the rearrangement, the number of students in each of the teams becomes: Aerobics = 40, Hockey = 34+f, Football = 30+d.
The additional six will be redistributed between d and f. Hence,
d+f = 28.
For any values of d and f, either 34+f or 30 +d > 40. Therefore, Hockey team or Football team has the maximum number of students.
