Data for Questions 1 to 5 :
Abhay, Balbir, Chandan, Dinesh and Eklakh are alumni of the IAS academy in Mussoorie. They are in Mussoorie to attend an alumni meet along with their wives Priya, Quindal, Riya, Shailja and Tulsi, (not necessarily in the given order). They stay in the guestroom of the academy in rooms numbered from 101 to 105. One interesting thing is that each couple’s wedding anniversary is on the coming Friday.
i. No two married couples were married in the same year.
ii. Balbir whose wife is not Shailja was married three fourths of as many years ago as Dinesh.
iii. Eklakh is staying in room number 103.
iv. Priya was married five years before Abhay and three years before Eklakh.
v. Only Shailja’s room is in-between Abhay’s and Eklakh’s room.
vi. Abhay, who was married before Shailja, was married five years after Chandan got married.
vii. The couple staying in room number 101 got married 10 years before the couple staying in room 104.
viii. Quindal is staying in room number 102.
ix. Tulsi was married before Riya and she was married 12 years before Quindal got married
1. Who is the husband of Riya?
d) Data inadequate
Explanation: The initial grid to start off would be something like:
The following deductions would follow:
From Clues (ii), (iii), (iv) and (v) the grid would evolve to:
Besides, from these 4 clues we could also realise the following additional deductions:
(a) Order of marriage
(From Clue iv)
(b) Shailja must be in either 102 or 104.
(c) Abhay’s room must be either 101 or 105
Using Clue (vi) we get that Shailja is not Abhay’s wife and neither is she Chandan’s wife. (Since Chandan was married before Abhay and Shailja was married after Abhay). Hence, she must be Dinesh’s wife.
Also, Clue (viii) gives us that Quindal is in Room 102, hence from deduction (b) above Shailja mustbe in Room 104 and consequently Abhay must be in Room 105. The table would evolve to:
Note: One additional deduction we have drawn in the above table is that Quindal (being in Room102) cannot be the wife of either Abhay (105) or Eklakh (103). Hence R and T would be the wives of A and E (in random order) as they have to be shared between A and E.
This also means that P and Q must be shared between B and C. Thus the grid evolves to:
At this point use Clue (ix), along with the deduction
Since Tulsi and Riya have to be shared between Abhay and Eklakh and Eklakh has got married before Abhay, he must be married to Tulsi and Abhay to Riya. The grid would evolve to:
At this stage if you try to draw a time line for their marriages, you would get the following figure :
If we use the logic contained in Clue (vi), we get that Abhay married 5 years after Chandan. Hence, Chandan and Priya must be married. Consequently Quindal and Balbir must be married. Also, since Balbir got married 3/4th the number of years ago as Dinesh we can conclude that Balbir got married 15 years ago. Based on these deductions the timeline looks like:
The final table is:
Abhay. Option (b) is correct.
2. Who is celebrating the silver jubilee of his marriage anniversary?
d) Data inadequate
Explanation: Abhay has been married for 25 years. Option (b) is correct (Refer explanation of Question 1)
3. Who is the wife of Balbir?
d) Data inadequate
Explanation: Quindal. Option (b) is correct (Refer explanation of Question 1)
4. If rooms are allotted on the basis of their married years, then which room number does not need shifting of its occupants? (105 is allotted to couples of maximum married years and 101 is allotted to couples of least married years).
d) All rooms need a shift
Explanation: All the rooms would need to shift. Option (d) is correct (Refer explanation of Question 1)
5. For how many years has Eklakh enjoyed his married life?
d) Data inadequate
Explanation: 27 years. Option (b) is correct (Refer explanation of Question 1)
6. Persons X, Y, Z and Q live in red, green, yellow or blue coloured houses which are in a sequence on a street. Z lives in a yellow house. The green house is adjacent to the blue house. X does not live adjacent to Z. The yellow house is in between the green and red house.
The colour of the house X lives in is:
d) Not possible to determine
Explanation: We have two possible combinations.
But from both combinations we get that X lives in the blue house. Option (a) is correct
7. Five persons with names P, M, U, T and X live separately in any one of the following: in a palace, a hut, a fort, a house or a hotel. Each one likes two different colours from among the following: blue, black, red, yellow and green. U likes red and blue, T likes black. The person living in a palace does not like black or blue. P likes blue and red M likes yellow. X lives in a hotel. M lives in a:
Explanation: M would live in a palace as U,T and P like either black or blue and X lives in a hotel. Option(b) is correct.

Data for Questions 9 & 10: Amitabh, Bhagyashree, Chunky, Dharmendra, Ekta, Farhan and Govinda are students of a class. Eachof them has a different favourite subject, viz., Economics, Commerce, Zoology, Sociology, Statistics, Urdu and Computers but not necessarily in the same order. There are two such students whose one sister each is there in the group. There is no other relation among the students. No boy likes Commerce or Urdu. Dharmendra, who does not like Sociology and Statistics, is the brother of that student who likes Computers. The student who likes Sociology is the sister of that boy student wholikes Economics. F is a boy student, B is sister of A
9. Which of the following is a pair of brother-sister other than Amitabh and Bhagyashree?
a) Dharmendra and Govinda
b) Dharmendra and Chunkey
c) Dharmendra and Ekta
d) Data Inadequate
Explanation: The first piece of information that fills the blanks is that no boy likes Commerce or Urdu. Then next information that is useful is that Dharmendra does not prefer Sociology and Statistics and is a boyhence he does not like Urdu and Commerce also. He is also brother of the person who opts for Computers. (Thus the person opting for computers must be a girl). So he must be having either Economics or Zoology. Now we are given that Amitabh and Bhagyashree are brother and sister and, hence Amitabh and Bhagyashree both will not have computers. Also Farhan is given as a boy student hence, by default from previous information, he does not like Urdu and Commerce, and also since he is a boy he cannot be Dharmendra’s sister and thus cannot have computers. Thus, we have covered all the possibilities for boys except for the pair of brother and sister having Economics and Sociology
Clearly since Amitabh and Bhagyashree are the only brother and sister mentioned in the information, they must be the ones having those subjects. Consequently Dharmendra must be having Zoology andFarhan would have Statistics. Commerce, Urdu and Computers would be shared between Chunky,Ekta and Govinda in some random order. Hence, they must be girls. The resultant table can be drawn as follows:
Option (d) is the correct answer as we do not know who Dharmendra’s sister is
10. Which of the following is true?
a) Dharmendra likes Commerce.
b) Chunky, Bhagyashree and Dharmendra are girl students.
c) The number of girls is more than that of the number of boys in the group.
d) None of these
Explanation: Option (c) is the correct answer as there are 4 girls in the group
