The CLAT reasoning portion had 27 questions from Analytical Reasoning. There were 2 questions (of arrangements) whose options were marked wrong. One question from blood relation which had no option available. And another one question from blood relation which had two possible answers. Further, there was a question on directions which was repeated.
Direction for Question Numbers 1 – 3: Read the following information carefully and choose the appropriate option in the questions given below.
- There is a group of five persons – A, B, C, D and E.
- One of them is a Singer, one is a Dancer, one is a Painter, one is a Teacher and one is a Doctor.
iii. Three of them – A, C and Doctor prefer rice to chapatti and two of them – B and the Painter prefer chapatti to rice.
- The Teacher, D and A are friends to one another but two of these prefer chapatti to rice.
- The Singer is C’s brother.
Q.1. Who is a Singer?
Q.2. Who is a Dancer?
Q.3. Who is a Teacher?
Sol 1 to 3: As, three of them – A, C and Doctor prefer rice to chapatti and two of them – B and the Painter prefer chapatti to rice , this means A and C are not doctors while B is not a painter.
|Profession||Not Doctor||Not Painter||Not Doctor|
Also, Doctor prefers Rice and Painter prefers Chapatti.
Further, it is given that the Teacher, D and A are friends to one another but two of these prefer chapatti to rice. This means, Teacher and D would prefer Chapatti as it is already known (in above table) that A prefers Rice. Further, as three of them prefer Rice, so E must prefer Rice.
Now as A, C and Doctor prefers rice, E should be the doctor (as the other two aren’t). Also, it is known that painter prefers Chapatti, so the only possibility – D should be the painter. Further, as Teacher also prefers Chapatti – this means B is the Teacher.
From the last statement : The Singer is C’s brother – we get that C is not the singer. This means A is the singer and C is the dancer.
Hence, the final table looks like –
Q1) 1 Q2) 2 Q3) 4
(Note: Two questions Q2 and Q3 of the above set had wrong answers)
Direction for Question Numbers 4 – 6: Read the following information carefully and choose the most appropriate option in the questions given below.
- Six flats on a floor in two rows facing North and South are allotted to P, Q, R, S, T and U.
- Q gets a North–facing flat and is not next to S.
iii. S and U get diagonally opposite flats.
- R, next to U gets a South–facing flat and T gets a North–facing flat.
Q.4. Which of the following combination gets South–facing flats?
- U, R, P
- Q, T, S
- U, P,T
- Data inadequate
Q.5. Whose flat is between Q and S?
Q.6. If the flats of T and P are interchanged, who’s flat will be next to that of U?
Sol 4 to 6: As it is not given that there are equal flats in each row. So, there are two possible cases-
Case 1: Assuming that there are 3 flats per row.
R, next to U gets a South–facing flat.. this means R and U are south facing flat. Also, as S and U are diagonally opposite each other.. it means S is a north facing flat. Thus, the arrangement would look like –
Now, as Q gets a North–facing flat and is not next to S. Thus, the arrangement would look like –
Also, as T gets a North–facing flat, therefore P will get a south facing flat.
Thus, the final arrangement looks like –
The answer options are as follows –
Q4) 1 Q5) 1 Q6) 2
Direction for Question Numbers 7 & 8: Which alternative applies to the following Statement or Assumptions? Choose the most appropriate option.
Q.7. ‘Only ignorant people believe in witchcraft’ is equivalent to:

- No ignorant persons are those who do not believe in witchcraft.
- All persons who believe in witchcraft are ignorant.
- There is no link between ignorance and witchcraft.
Q.8. ‘There is no man that is not naturally good’ is equivalent to the proposition:
- All men are naturally good.
- Some men are naturally good.
- Some men are not naturally good.
- No men are good.

- Open secret
Q.10. Find the odd one out from the following:
Direction for Question Numbers 11 to 40: Choose the most appropriate option for each of the following questions.
Q.11. Ravi was showing a photograph to his friend, Gopi. Pointing at a boy in the photograph, Ravi said: ‘The boy sitting at the left is the son of the wife of the only son of the grand–mother of my younger brother’.
What is the relation between the boy in the photograph and Ravi?
- First Cousins
- Nephew and uncle
- Ravi’s brother–in–law
Sol 11: Ravi’s younger brother’s grandmother = Ravi’s grandmother
Ravi’s grandmother’s only son = Ravi’s father
Ravi’s grandmother’s only son’s wife = Ravi’s mother
The boy in the photograph is the son of Ravi’s mother i.e. Ravi and the boy in photograph are siblings i.e. brothers.
Q.12. wave: crest as _________ : peak.
Q.13. If in a code language, ‘ABANDON’ is written as ‘aramoim’; ‘BORE’ is written as ‘rits’ and ‘BASIL’ is written as ‘rabut’, then what is the original word for the code: ‘bituo’?
Sol 13: This is a type of ordered coding. A is coded as a, B is coded as r, N is coded as m and so on. Thus, bituo will be the code for SOLID.
(Note: Although ‘t’ was the code for R and L both, however, none of the options had R for the same).
Q.14. A girl introduced a boy as the son of the daughter of the father of her uncle. The boy is girl’s:
Sol 14: Girl’s uncle’s father = Girl’s grandfather (paternal or maternal)
Girl’s uncle’s father’s daughter = Girl’s grandfather’s daughter = Girl’s aunt or girl’s mother
The boy is the son of the girl’s aunt or girl’s mother.
The boy and girl could be cousins or siblings. Thus, the boy would be the brother.
(Note: Even if you take girl’s grandfather as paternal grandfather, the answer would have been cousin (who is a male), thus you could have marked the best option as brother).
Q.15. Two ladies and two men are playing bridge and seated at North, East, South and West of a table. No lady is facing East. Persons sitting opposite to each other are not of the same sex. One man is facing South. Which direction are the ladies facing to?
- South and East.
- North and West.
- East and West.
- None of these.
Sol 15: One man is facing south, thus one lady will be facing north (as persons opposite to each other are of opposite sex.) Further, as no lady is facing east, another lady will face west and another man will face east. Thus, the ladies are facing north & west. Option, (2)
Q.16. The birthday of Ms. Y was celebrated six days before Ms. X, who was born on 4th October 1999. The independence day of that year fell on Sunday. On which day did Ms. Y celebrate her birthday, if it was not a leap year?
Sol 16: Ms. X birthday = 4th October
Ms. Y birthday = 28th September
Given, 15 August was on Sunday
Now, calculating odd days Aug (16 days left) = 2 odd days, Sept (till 28th) = 0 odd day
i.e. 2 odd days
i.e. Ms. Y was born 2 days after Sunday = Tuesday
(Note: Leap year had nothing to do with the question)
Q.17. In a company, 60 % workers are males. If the number of female workers in the company is 800, what is the number of male workers in the company?
Sol 17: If 60% workers are males, thus 40% workers are females.
Now, 40% of total = 800
Thus, 60% of total = (800/0.4) * 0.6 = 1200
Q.18. How many times from 4 pm to 10 pm, the hands of a clock are at right angles?
Sol 18: Every hour the hands of a clock are at right angles twice i.e. in 6 hours (4 to 10) they would be right angles to each other 12 times. However, since 3 o clock is the common time in time range 2 to 3 and 3 to 4, thus we subtract this once due to repetition in counting. Thus, from 4 pm to 10 pm the two hands of a clock will be perpendicular to each other 11 times. Option, (1)
Q.19. If 27th March, 2011 was Sunday, what was the day on 27th June, 2011?
Sol 19: 27th March 2011 -> Sunday
Now, finding odd days
March (4 days left) = 4 odd days ; April (full month) = 2 odd days, May (full month) = 3 odd days; June (till 27) = 6 odd days
Now, total odd days = 4 + 2 + 3 + 6 = 15 i.e. 1 odd day
i.e. 27th June 2011 is 1 day after Sunday i.e. on Monday
Q.20. Pointing to a photograph, Prakash said, ‘She is the daughter of my grandfather’s only son’. How is Prakash related to the girl in the photograph?
Sol 20: Grandfather’s only son = Father (Assuming grandfather as paternal)
Thus, Prakash’s grandfather’s only son’s daughter will be Prakash’s sister. This means Prakash (considering him to be a male) will be the brother of the girl.
Q.21. If in a certain code, the word MILITARY is written as 12324567, then in the same code, the word TAIL will be written as:
Sol 21: This is a type of ordered coding i.e. M is coded as 1, I as 2, L as 3 and so on. Thus, TAIL will be coded as 4523
Q.22. Identify the statement which cannot be accepted.

Q.27. There were twelve dozens of chocolates with a shopkeeper. Ten chocolates were distributed by the shopkeeper to the children of his colony. The shopkeeper then added two more dozens of chocolates in his stock. If the shopkeeper divided the total chocolates equally in two different packets, then how many chocolates were there in each packet?
Sol 27: Total chocolates before distributing to children = 12 *12 = 144
10 chocolates were given to children, then number of chocolates left = 144 – 10 = 134
However, two more dozens of chocolates were added, then total chocolates = 134 + 24 = 158
Number of chocolates per packet = 158 /2 = 79
Q.28. ‘Some of the valuable books are seldom read’, means:
- All the valuable books are not read.
- Some of the valuable books are read.

Q.29. If South–East becomes North, North–East becomes West and so on, what will West become?
Sol 29: South-east becomes north, north-east becomes west, thus, west will become south –east. Option, (1)
Q.30. When Ravi saw Ramesh, he recalled, ‘He is the son of the father of my daughter’. Who is Ramesh?
Sol 30: Ravi’s daughter’s father = Ravi himself (in case Ravi is a male)
Now, Ramesh is the son of his daughter’s father i.e. of Ravi
i.e. Ramesh is Ravi’s son.
Even if we consider Ravi to be a female, Ramesh is the son of Ravi.
(Note: This question is not clear in sense that Ramesh is who’s who. Also if we talk w.r.t to Ravi, then Ramesh is Ravi’s son, which is not available in options)
Q.31. Sunil’s school bus is facing North when it reaches his school. After starting from Sunil’s house, it turned right twice and then left before reaching the school. What direction the bus was facing when it left the bus stop in front of Sunil’s house?
Sol 31: From, school if we go back to home. We first turn the bus south. Now, turn right i.e. west, then turn left i.e. south and again turn left i.e. east. This means initially the bus must have been facing west (as it faces east when it enters his house). Option, (3)
Q.32. Vaishnavi prefers Economics to Maths, English to Social science, and Political Science to History. If she prefers Maths to History, and Social science to Maths, which is Vaishnavi’s least preferred subject?

Sol 32: The answer is History. Just check options. Economics is preferred over Maths. Maths is preferred over History and also Social is preferred over Maths.
Q.33. A man walks 1 km. towards East and then he turns to South and walks 5 kms. Again he turns to East and walks 2 kms. After this he turns to North and walks 9 kms. Now, how far is he from his starting point?
- 10 kms.
- 9 kms.
- 5 kms.
- 4 kms.
Sol 33: Distance moved in horizontal direction = 1 + 2 = 3 kms
Distance moved in vertical direction = 9 – 5 = 4 kms
The shortest distance = 5 kms
Q.34. John wants to go the university. He starts from his house which is in the East and comes to a crossing. The road to his left ends in a theatre, straight ahead is the hospital. In which direction is the University?
Sol 34: This question was a little vague as it was no where mentioned that house, theatre, hospital and university were all in different directions, and , also that we are not sure John walks in which direction from his house.
However, we believe that most of the candidates might have taken the most obvious situation that person moves from east to west. In west is the hospital and To left (i.e. towards south) is theatre, thus, university is in the north.
The correct answer for same should have been Cannot be determined.
Q.35. Coding and decoding 9: 72 : : 8 : ?
Sol 35: 9 : 9 *8 Thus, 8 : 8*8 = 64
Q.36. Pointing to a girl in the photograph, Ram said, ‘Her mother’s brother is the only son of my mother’s father’. How is the girl’s mother related to Ram?
Sol 36: Ram’s mother’s father = Ram’s maternal grandfather
Only son of Ram’s maternal grandfather = Ram’s maternal uncle
Now, Ram’s maternal uncle is girls mother’s brother i.e. Ram’s maternal uncle is also the girl’s maternal uncle. This means, Ram and girl could be siblings (or) cousins. Thus, girl’s mother could be related to Ram as his mother (or) aunt.
(Note: Both options were available. Although the answer is marked as aunt, however, mother is also a correct answer as explained above).
Q.37. A person who renounces religious or political belief or principle is called:
