PART A
PAPER OF APTITUDE REASONING FOR INFOSYS
Questions: 30 Duration: 40 Minutes
Directions (Questions 6-10) Each of the following Questions consists of five options. Choose the best option that suits the question given.
6. Nithin was counting down from 32. Sumit was counting upwards the numbers starting from 1 and he was calling out only the odd numbers. What common number will they call out at the same time if they were calling at the same speed?
A. 19 B. 21 C.22 D.They will not call out the same number
E. None of these.
Ans: D Explanation: Nithin: 32 31 30 29 28 27 26 25 24 23 22 21 20….. Sumit: 1 3 5 7 9 11 13 15 17 19 21 23 25… Clearly it is seen that they never call out same nmber at the same time.
7. Radha moves towards South-east a distance of 7 km, then she moves towards West and travels a distance of 14m. From here, she moves towards North-west a distance of 7 m and finally she moves a distance of 4 m towards East and stod at that point. How far is the starting point from where she stood?
A. 3 m B. 4m C.8 m D10 m E.11 m
Ans:D Explanation: The movements of Radha are shown as below:
Clearly Radha’s distance from starting point O = OD = (OC –CD) =(AB-CD) = (14-4) m = 10 m
8. In a certain office, 1/3 of the workers are women, ½ of the women are married and 1/3 of the married women have children. If 3/4 th of the men are married and2/3 rd of the married men have children, what part of workers are without children?
A. 5/18 B. 4/9 C. 11/18 D17/18 E.17/36
Ans: C Explanation: Let total no. of workers be x Number of women = x/3 and number of men = 2x/3 Women married=1/2 * x/3 = x/6 Women having children = 1/3 *x/6 =x/18 Married Men =3/4 *2x/3 = x/2 Men having Children =2/3 * x/2 = x/3 Workers with children = x/3 + x/18 = 7x/18 Hence, workers without children = x- 7x/18 = 11x/18
9. A, P, R, X, S and Z are sitting in a row. S and z are in the centre. A and P are at the ends. R is sitting to the left of A. Who is to the right of P?
A. P B. A C.X D.S E.Z
Ans: C Explanation : The seating arrangement is as follows : P X S Z R A Hence , right of P is X.
10. Introducing a boy, a girl said, "He is the son of the daughter of the father of my uncle." How is the boy related to the girl?
A. Brother B. Nephew C. Uncle D. son in law E. grand father
Ans: A Explanation:

Directions (Questions 11-12): Each Question Given Below has a problem and two statements numbered I and II giving certain Information. You have to decide if the information given in the statements is sufficient for answering the problem. Indicate your answer as (i) if data in statement I alone are sufficient to answer the question; (ii) if data in statement II alone are sufficient to answer the question; (iii) if data either in I or II alone are sufficient to answer the question; (iv) if the data even in both the statements together are not sufficient to answer the question; (v) if the data in both the statements are needed.
11. Is Anil taller than Sachin? I. Dinesh is of the same height as Arun and Sachin. II. Sachin is not shorter than Dinesh.
A. i B. iii C. ii D. v E. iv
Ans: A Explanation: From statement I, we can conclude that Dinesh, Arun and Sachin are of same height. So, Arun is not taller than Sachin. So, only statement I is sufficient to answer the question.
12. In a certain code language, ‘13’ means ‘stop smoking’ and ‘59’ means ‘injurious habit’. What is the meaning of ‘9’ and ‘5’ respectively in that code? I. ‘157’ means ‘stop bad habit’ II. ‘839’ means ‘smoking is injurious’.
A. ii B. iii C. v D. iv E. i
Ans: B Explanation: ‘59’ means ‘injurious habit’ and ‘157’ means ‘stop bad habit’. Hence common letter ‘5’ denotes ‘habit’. Hence ‘9’ is obviously ‘injurious’. So I alone can be sufficient. Also, ‘59’ is ‘injurious habit’ and ‘839’ is ‘smoking is injurious’ from which it can be implied that ‘9’ is ‘injurious’. Hence II alone can also be sufficient. Hence either I or II alone can be sufficient.
Directions (13- 15): In the following problem, there is one question and three statements I, II and III below the question. You have to decide whether the data given in the statements is sufficient to answer the question. Read all the statements carefully and find out the probable pair which can be sufficient to answer the question.
13. Five persons --- A, B, C, D and E are sitting in a row. Who is sitting in the middle?
I. B is in between E and C.
II. B is to the right of E.
III. D is in between A and E.
A. I and II together
B. II and III together
C. I and III together
D. I, II and III together
E. Data insufficient.
Ans: D Explanation: From I, the order is E, B, C or C, B, E. From II, the order is E, B. From III, the order is A, D, E. Combining all the three, we get the order as: A, D, E, B, C. Clearly, E is sitting in the middle. Hence all the three statements are required.
14. Four Subjects --- Physics, Chemistry, Mathematics and Biology were taught in four consecutive periods of one hour each starting from 8.00 a.m. At what time was the Chemistry period scheduled?
I. Mathematics period ended at 10.00 am which was preceded by Biology.
II. Physics was scheduled in the last period.
III. Mathematics period was immediately followed by Chemistry.
A. Only I B. Only I or II C. Only II D. II and III together.
E. I and II together or I and III together
Ans: E Explanation: From I and II we conclude that Mathematics period began at9.00 a.m., Biology period began at 8.00 a.m. and Physics period began at 11.00 a.m. So, the Chemistry period began at 10.00 a.m. From I and III, it is clearly seen that Mathematics period ended at 10.00 a.m. followed by Chemistry to start at 10.00 a.m.
15. How many sons does Sharma have?
I. Saurav and Aditya are brothers of Sonali.
II. Ayesha is sister of Sharmila and Aditya.
III. Ayesha and Sonali are daughters of Sharma.
A. I and II only. B. II and III together. C. I, II and III together
D. I, II, III together are not sufficient E. I and III together
Ans: C Explanation: From I, Saurav, Aditya and Sonali are siblings. From II, Ayesha, Sharmila and Aditya are siblings. It implies that Saurav, Aditya, Ayesha, Sharmila and Sonali are siblings. This is supported by III.
Directions (Questions 21-25): The following questions are based on the information given. Choose the appropriate answer that suits the question based on the information.
A cube is cut in two equal parts along a plane parallel to one of its faces. One piece is then colored red on the two larger faces and green on remaining.

PLACEMENT TEST PAPER PATTERN FOR INFOSYS
Placement pattern for Infosys consists of two rounds: the written test and a final HR. Clearing the written test implies that the chance of being selected to Infosys is almost done. The written Test consists of two test patterns:
APTITUDE REASONING TEST QUESTIONS: 30 DURATION: 40 MINUTES 2. VERBAL ABILITY QUESTIONS: 40 DURATION: 35 MINUTES
The Aptitude reasoning test pattern is distributed into 6 different topics with 5 questions each as:
1. PICTURE REASONING (5 questions)
In this section, a series of pictures are given which may consist of picture series, picture analogy or picture classification.
2. STATEMENT REASONING(5 Questions)
In this section, sequence questions like seating arrangement or money distribution or height arrangement are given. A set of five questions are based directly on the statements given.
3. DATA SUFFICIENCY (5 questions)
Here a set of two statements are given followed by 5 options which satisfy the answer for the statements. You have to decide which option best suits the answer.
4. DATA INTERPRETATION (5 questions)
This section consists of a direct sequence of 5 questions based on the data which is provided in the form of table charts, bar charts, pie charts or line charts.
5. RELATION PROBLEM (5 questions)
This section consists of questions which are similar to the sets and relations like students with biology, maths, physics and chemistry, maths and biology, only physics, etc., and questions related as such.
6. SYLLOGISM (5 questions)
This section consists of statement followed by two conclusions. We need to pick out from 5 options which suits the best answer
The Verbal Ability test pattern is distributed into 5 different topics as:
1. SENTENCE CORRECTION (8 questions)
Among 4 sentences the correct one should be detected
2. UNDERLINED A PART OF SENTENCE AND ASKED TO INSERT CORRECT PHRASE IN IT FROM THE GIVEN 4 OPTIONS (8questions)
3. FILL IN THE BLANKS (8questions)
4. THEME DETECTION (6 questions)
5. TWO READING COMPREHENSIONS (10 questions)
