INFOSYS ANSWER KEY 1
LOGICAL ABILITY:
1)4
2)2
3)4
4)3
5)4
6) C. Statement 1 by itself is not sufficient. One of the two variables could be a small fraction. (Think of 500 and 0.01.) Statement 2 by itself could yield the product of 3 and 4. However, the information from both statements is taken together, we can definitively state that the answer to this question is "true."
7) A. Statement 1 is sufficient to determine that Y equals 5. Statement 2 only tells us that Y could be +5 or -5.
8) E. The statements, together as well as alone, do not give enough information to answer the question. To determine the percent change, we would need one of the additional pieces of information:
a. The beginning stock price for the month.
b. The ending stock price for the month.
c. The percent change in the stock for the second half of the month.
9) E. The question can not be answered with the statements provided. Because x can be an even number and still be prime (2 is a prime number), statement 1 is insufficient. Additionally, x might be divisible by even numbers, so statement 2 is also insufficient.
10) C. Recall that the sum of the 3 accounts is $3 million. If the largest is $1.3 million, then the sum of the other two accounts must be $1.7 million. Since the second-largest account could be $1.29 million, then the smallest account could be $0.41 million, which is less than $0.5 million. Hence, Statement 1 by itself is insufficient.
However, if we know the value of 2 of the variables (as we do if we read statements 1 and 2 together), and the average value of all three variables (as we do from reading the question), then we can determine the value of the third variable. If the largest account is worth $1.3 million and the smallest is worth $0.7 million, then the third variable must be $1.0 million. With the value of all 3 variables, we can quickly determine the value of the smallest variable. Statements 1 and 2 together give us the information needed to answer the question.

Clearly, the lady is the grandmother of man’s sister’s son.
i.e., the mother of the mother of man’s sister’s son.
ie., the mother of man’s sister.
So, the lady is man’s mother

13. 9…..The number at the centre of each triangle equals the sum of the lower two numbers minus the top number.
14.40 socks….If he takes out 38 socks, although it is very unlikely, it is possible they could all be blue and red. To make 100 percent certain that he also has a pair of black socks he must take out a further two socks.
15. Gordon 64 and Tony 48
When Gordon was 48, Tony was 32(ie half the age Gordon is now).
ANALYTICAL ABILITY :
1. a)34.. The pattern is - 11, - 13, - 15, - 13, Missing number = 45 - 11 = 34.
2. a)312….The pattern is + 20, + 40, + 80, number = 152 + 160 = 312.
3. a)1260…….A team of 6 members has to be selected from the 10 players. This can be done in 10C6 or 210 ways.
Now, the captain can be selected from these 6 players in 6 ways.
Therefore, total ways the selection can be made is 210*6 = 1260.
Alternatively, we can select the 5 member team out of the 10 in 10C5 ways = 252 ways.
The captain can be selected from amongst the remaining 5 players in 5 ways.
Therefore, total ways the selection of 5 players and a captain can be made = 252*5 = 1260.
4. c)0.9
the room will be lightened if any of the bulb is OK, or any two bulbs are OK or all the three bulbs are OK.
so, no. of favourable cases will be = 6c3*6c0 + 6c2*6c1 + 6c1*6c2
= 20 + 90 + 90 = 200
total no. of cases = 12c3 = 220
prob. = 200/220 = 0.909
5. c) The first and the last letters of the word remain as such and the remaining letters are written in a reverse order, to obtain the code.
6. d)None
7. d)B,C
8. b)A is second right of E
9. c)H
10. d)E
VERBAL ABILITY :
1) D
To figure out what the missing words are, try to predict their definitions by using keywords from the prompt. Here, there are
three keywords: “answer,” “rarely,” and “address.” “Answer” and “address” are both modified by missing words that must refer to how the questions were answered, and “rarely” gives the relationship between them, making it clear they should be opposites: Nixon was able to answer questions one way and rarely answered questions the other way. Thus, the missing words’ meanings cannot be predicted, but the correct choice must provide a pair of antonyms. Of the choices, only choice (D)
provides a pair of antonyms, as obliquely means not in a straightforward manner, while directly means in a straightforwardmanner.
(A) is incorrect because it does not provide a pair of antonyms. Audaciously means bravely, while brazenly meansshamelessly. If anything, these words are synonyms.
(B) is incorrect because it does not provide a pair of antonyms. Ambiguously means vaguely or indirectly, while disingenuouslymeans lacking in frankness. Both words, then, essentially would imply that Nixon was unable to answer questions head on.
(C) is incorrect because it does not provide a pair of antonyms. Unequivocally means clearly, while absolutely means certainly.Thus, these two words are essentially synonyms and would both imply that Nixon could not be vague.
(E) is incorrect because it does not provide a pair of antonyms. Bluntly means frankly or without sensitivity, while explicitly means clearly. If anything, these words are synonyms, though the prompt requires a pair of antonyms.
2) C
To figure out what the missing word is, try to predict its definition by using keywords from the prompt. Here, the keywords are “disrespect his elders,” which means that Timothy did or said something rude to an adult. The missing word describes something Timothy possesses, and, since we only know that he is rude, the missing word must mean rudeness. Therefore, choice (C) is correct, since impudence means impertinence or audacious rudeness.
(A) is incorrect because jauntiness is cheerfulness. This word does not work because cheerfulness has no relationship to rudeness.
(B) is incorrect because reverence is respect, something a rude child would almost certainly not possess.
(D) is incorrect because humility is modesty. The prompt indicates that the child was rude, not modest. (E) is incorrect because obsequiousness is flattery, something a rude child would probably not use.
3) A
To figure out what the missing word is, try to predict its definition by using keywords from the prompt. Here, the keyword is “reapply,” a word that implies that driving privileges must have been taken away from the driver who exceeded a certain number of points, as one would not need to “reapply” if one did not lose the license to begin with. Thus, the missing word must be one that means taken away. Therefore, the correct choice is (A), since revoked means taken away.
(B) is incorrect because recuperated means recovered from financial or physical loss. The prompt means to imply the opposite: driving privileges are not recovered until after the driver “reapplies for his or her license.”
(C) is incorrect because reprimanded means punished, and while the driver in the prompt is being punished for exceeding a number of driving points, the privileges themselves are not being punished. This answer does not make sense grammatically.
(D) is incorrect because curbed means limited. While the driver in question certainly will have more limited driving privileges, the prompt makes it clear that he or she will lose his or her license, as the driver must then “reapply” for it. This means that curbed is not extreme enough for the prompt.
(E) is incorrect because instituted means created or started. It is, thus, the opposite of what happens to driving privileges if a driver exceeds a number of points.
4) E
To figure out what the missing words are, try to predict their definitions by using keywords from the prompt. Here, the keyword is “though,” which implies a negative or opposite relationship between the two missing words. In this prompt, the cat is usually one way but was “was quite” the opposite way when she was “defending… her territory.” The prompt provides one additional clue in stating that she “would often win the fights she started.” This phrase implies that the two missing words relate to
fighting, meaning the correct choice will provide two antonyms relating to fighting. Peaceful means calm, while pugnacious means quick to fight. These words are opposites, so choice (E) is correct.
(A) is incorrect because the words are in the wrong order to work in context. Antagonistic means hostile and placatory means attempting to appease. This choice does not work because the prompt implies that the cat is usually placatory but could be antagonistic when she needed to defend her territory.
(B) is incorrect because the two words are synonyms, rather than the antonyms the prompt requires. Cantankerous means disagreeable or hostile, while belligerent means warlike, meaning both words imply that the cat is hostile.
(C) is incorrect because the two words are not opposites. Serene means calm and amicable means agreeable, so both words would imply that the cat is easy to get along with. The prompt, however, implies that the cat can be hostile and will “start fights.”
(D) is incorrect because the words are in the wrong order to work in context. Aggressive means hostile, while pacifistic means peace-loving. This choice does not work because the prompt implies that the cat is usually pacifistic but could be aggressive when she needed to defend her territory.
5) A
To figure out what the missing word is, try to predict its definition by using keywords in the prompt. Here, the keywords are “abused his power,” something that the councilwoman “alleged” the city manager did. The missing word likewise describes an allegation or accusation made about the city manager, so the missing word must be one relating to an abuse of power. A malfeasance is a wrongdoing committed by a public official such as a city manager, so choice (A) is correct.
(B) is incorrect because unscrupulousness is a lack of morality. While it implies wrongdoing, just as the prompt requires, it does not directly relate to an abuse of power. One can show unscrupulousness without being in a position of power.
(C) is incorrect because depravity is a lack of morality. While it implies wrongdoing, just as the prompt requires, it does not directly relate to an abuse of power. One can show depravity without being in a position of power.
(D) is incorrect because bribery is an act of giving or taking money to induce one into doing something he or she would otherwise not do. While bribery is an example of a finance-related wrongdoing, the prompt does not imply that the city manager bribed anyone; rather, it merely implies that the city manager in some way made a little more money than he should have.
(E) is incorrect because misconduct is misbehavior. While it implies wrongdoing, just as the prompt requires, it does not directly relate to an abuse of power. One can perform misconduct without being in a position of power.
6) C
To figure out what the missing word is, try to predict its definition by using keywords from the prompt. Here, the keywords come after the comma, in the descriptive clause “one that profoundly impacted Western theology for generations.” This clause elaborates on the “work” modified by the missing word, so the missing word must mean profoundly important. Because seminal means highly influential, choice (C) is correct.(A) is incorrect because controversial means causing controversy or scandal. While The Age of Reason might have been
controversial, the prompt only implies that it was not appreciated in its time period but was later seen as having import. There is not enough information in the prompt to definitively call it a controversial work.
(B) is incorrect because negligible means small in significance and is, thus, the exact opposite of an adjective that would be used to describe a work that “profoundly impacted” Western thought.
(D) is incorrect because trifling means insignificant and is, thus, the exact opposite of an adjective that would be used to describe a work that “profoundly impacted” Western thought.
(E) is incorrect because provocative means stimulating. While The Age of Reason is probably interesting and stimulating, the prompt is looking for a word that discusses the work’s impact and influence, not how interesting it is.
7) A
To figure out what the missing word is, try to predict its definition by using keywords from the prompt. Here the keywords are in the phrase “someone who constantly looks down on them,” a phrase that explains why Carlton was unpopular. The missing word likewise provides a cause for his unpopularity, so the missing word must be a noun that would describe one who is arrogant or looks down on others. Choice (A) provides such a word, as superciliousness is haughty contempt or arrogance.
(B) is incorrect because apathy is the absence of emotion or feeling for others. While such a trait would make one unpopular, the prompt provides a different explanation for Carlton’s unpopularity: the fact that he “looks down on” others.
(C) is incorrect because gregariousness is sociability or friendliness and is, as such, a trait that would not define someone who is “unpopular” and “looks down on others.”
(D) is incorrect because modesty is humility or a lack of arrogance. The prompt implies Carlton is anything but modest, as he “constantly looks down on” others.
(E) is incorrect because insensitivity is callousness or an inability to care for others. While such a trait would make one unpopular, the prompt provides a different explanation for Carlton’s unpopularity: the fact that he “looks down on” others.
