C3 C2 = 4
adding C1.
8 – 4 = 4 which is not possible because two even digits cannot be taken in column C, there are only 4 even digits and 3 of them have to be useful in column A.
7 – 3 = 4, 7 has to be used in column B, this is also wrong. 6 2 = 4, same logic applied for (8 4)
5 1 = 4. Only possible option we have.
Now A + B = 17 – 8 = 9
Possible options are (first digit in column A has to be even (2 + 7), 2 and 8 cannot be in the same row, therefore is wrong. 4 + 5, 5 has been taken at C3. 6 + 3 is the right combination.
Now 9 cannot be used below 3, therefore 7 will come below 3 and 9 will come below 7.4 cannot come left to 7. So, 6 will come in A1 and 4 in A3.
Hence, the answer is option [2]. 11. [2]

Jamuna sells lemons at 2 for 50 p rate / lemon=25 p
Seema sells lemons at 3 for 50 p rate / lemon= 50/3 p
Equal quantities of both types of lemons are left which is sold at the rate of 5 for 100 p Rate / lemon= 20 p
Let us consider that no. of lemons left when Seema left is 60 each. As per their rates,
Seema should get 60 × (50/3) p = 10 Rs. Jamuna should get 60 × (25) p = 15 Rs. Total they should get Rs. 25
But it is sold at the rate of 20 p So, total money = 120 × 20 p = 24 Rs. So, loss = Rs. 1, for 60 lemons. Actual loss = Rs. 3.5
So, number of lemons = 210
So, on selling 210 lemons Jamuna should get 210 × 25 p = 52.5 Rs. But she receives 210 × 20 p = 42 Rs.
Therefore loss = 52.5 42 = 10.5 Rs. Hence, answer is option [1].

M, N O & P all are different individuals.
Let’s make a family tree for the given conditions:
As per the above tree: ‘O’ is the father of N & P. N is the father of M. Now, let’s go by answer options
Option [1]: P is the father of M:
From above family tree we know that N is the father of M. Hence, the given statement (a) is contradictory.
Option [2]: ‘O’ has three children:
We are not sure how many children do ‘O’ have, because the total number of members in the family is not given, hence, the number of children could be three. Hence not contradictory. Same is the case with option [3] & [4].
Hence, the answer is option [1]. 28. [4]
On a hot day, land gets heated faster than sea water because temperature on land becomes more than the temperature on sea water, so air pressure on the land becomes lower than air pressure on the sea. Wind flows from high air pressure to low air pressure, so it flows from sea to land. Hence, the answer is option [4].

An adjective modifies or describes a noun. The word ‘then’ in sentence 5 tells us that the person was King at that point of time. An adverb is a word or phrase that modifies or qualifies another word. In sentence 8, then gives us the time period when he was a graduate (adverb clause of time). A conjunction is a word used to connect clauses or sentences or words in the same clause. This is the function of ‘then’ in sentence 7. Therefore, 1-6 should be the last pair.
70. [4]
The author makes his view clear when he says from the sentence ‘If we refuse to even try to ………”. The sentence tells us that men have better reasoning abilities than animals and therefore they must explore the frontiers of science further.

The word “sanctimonious” means to make a hypocritical show of being virtuous or righteous. The writer is of the opinion (in paragraph 2) that those who are concerned about the increase in the number of cars are actually concerned about the inconvenience it would cause them. They are not really concerned about the ecological effects. The idiom “holier than thou” also refers to the same hypocrisy. Thus, the answer is delete is option [3]. The other answer options do not convey the same meaning, so they can be eliminated.
72. [4]
This is an indirect question. The author says in the 2nd paragraph that the elite are not really concerned that the increase in the number of cars will cause pollution. The actual issue, according to the author, is that “they cannot stand the poorer masses becoming mobile”. This means that they look down upon them for owning cars. The other answer options do not refer to this issue specifically, thus they can be eliminated.
73. [3]
The word paradox refers to a contrast in a given situation. This contrast is mentioned in the 3rd paragraph of the passage, where the author is trying to disprove the notion that more cars lead to more pollution. This is the main contention that environmentalists have against the Nano. Option [1] does not talk about a contrast. The passage does not say that the Nano will bring in more pollution. In fact the author is saying just the opposite. So option [2] can be eliminated. The author does not talk about the relative sizes of the countries, so option [4] is also incorrect.
74. [4]
“Ironical” means contradictory. In the 5th paragraph, the author is trying to say that there is a contrast between the limited amount of available parking space and the cost of that space. Therefore, the tone of the author can be interpreted to be ironical. “Caustic” would refer to a very sharp or scathing manner of speaking which is meant to hurt a person. “Exaggerating” means overstating or magnify beyond the limits of truth. But the passage does not suggest that the author is overstating facts, so option [2] can be eliminated. “Sarcastic” would mean to indirectly insult someone, but the author is not insulting anyone in the passage.
75. [2]
This is clearly stated in the 8th paragraph. By subsidizing diesel, manufacturers make more diesel-run vehicles, which cause pollution. The author does not talk about kerosene in relation to green house emissions, so option [1] can be eliminated. The governments plan to increase parking rate was foiled (paragraph 6), so option [3] is incorrect. In the 12th paragraph, the author says that making parking space compulsory for car-owners is very extreme for India, which means that he knows that the Indian government will not be able to implement this move as it is not practical. So, option [4] can also be eliminated.
76. [1]
The author argues in the entire passage that it is the failure of government policies that has lead to a rise in the pollution levels in the country. Thus, the most appropriate title would be option [1] which expresses the main idea of the passage. The author is not against the launch of the Nano, so option [2] is incorrect. Subsidies is only one of the issues that the author discusses in the passage, so option [3] can also be eliminated. Option [4] does not mention the main idea of the passage, so it can be eliminated.

The author refers to the Mets primarily in order to illustrate the failure of statistical predictions. The sentence suggests that the Mets have a low batting average i.e. a low success rate. The author compares this to the success rate of the census by saying that this is even lower.
89. [1]
The author gives a number of humorous examples such as ‘a batting average below the Mets’ to illustrate his points. Hence his tone can be said to be Jocular, which means humourous. The word “scornful” indicates a derisive tone, but the author is not disrespecting the census method, hence option [2] is incorrect. “Pessimistic” refers to someone who always looks at the negative side of things. “Humanistic” means someone who has a sense of welfare for human beings.

This is directly mentioned in the 3rd line of the second paragraph. It says that the bankers were counting on their reputations to encourage investors to increase the number of buy orders.
98. [4]
The first paragraph says that inexperienced investors began to sell their stocks as they panicked about the drop in prices. This led to a further drop in the stock markets which ultimately crashed. Option [1] is incomplete as it does not refer to the reason why inexperienced investors caused a decline in stocks. Option [2] does not tell us what has decreased. The lack of confidence on the part of the traders did not cause a decline. This was only an apprehension on their part which came true later, so option [3] is also incorrect.
99. [4]
The word “minimal” has been used in the 2nd line of the 2nd paragraph. The contextual meaning of the word here is “insignificant” as the sentence tells us that the buy orders were not enough to save the stock markets from a decline. Hence, the most appropriate antonym would be option [4], which says “significant”. “Maximal” would mean of highest value, which is not compatible with the contextual usage of the word “minimal”. So option [4] is a better answer. Option [1] is a synonym, so it can be eliminated. “Minimum” is also similar in meaning as it means least.
100. [2]

As we see the graph of line 1, there is no fluctuation in the straight line therefore no breakdown in line 1. Now in line 2, from month 4 to month 6 there is no increase in production, which is due to reported breakdown during this time. Therefore, A can be answered.
Now, if there was no breakdown in line 2, then production of month 5 and 6 would have increased but the amount in increase is indeterminable. Production loss cannot be quantified.
Hence, the answer is option [2]. 102. [3]
If first page is numbered (n), then the back side of the page will be numbered (n+1), the following page will be numbered (n +2) and so on. Now if the page missing is 9808, the page behind it is 9809,
sum cannot be 9808 option [1] is ruled out. If we verify option [3] first page is 291 and last page is 322 (back side)
The sum of page numbers = (291 + 322) × 32 / 2 = 9808
since, sum of ‘N’ consecutive numbers = (First term + last term)/2 × N ] Hence, the answer is option [3].
103. [2] 2, 3, 13, 37, 86, 167, 288 3 – 2 = 12 13 – 3 = 10 37 – 13 = 14 86 – 37 = 49 = 72 167 – 86 = 92 288 – 167 = 121 = 112 Error is in 13, it should be 12 3 – 2 = 12 12 – 3 = 32 37 – 12 = 52 86 – 37 = 72 167 – 86 = 92
288 – 167 = 112

Sc = Speed of cyclist
Sw = Speed of wind
Case I: Incoming journey [with wind] So, the relative speed = Sc + Sw
For case II:- Return journey [against wind] So, relative speed = Sc- Sw
For case I:- [with wind] Time = Distance/Speed
3 = 1/ (Sc + Sw) Sc + Sw = 1/3 …….….….… (1)
Similarly for case II [against wind] Sc- Sw = 1/4………. (2)
Solving (1) and (2) we get Sc = 7/24
So when no wind and d = 1 km Using d = S × t We get 1 = Sc × T we get T = 24/7 =
Hence, the answer is option [2]. 125. [3]
Let the total number capital be Rs. 60. Therefore investment A → Rs. 30 B → Rs. 20 C → Rs. 10 Let the total number time be 12 months Ratio of profit = ratio of EC = 2 : 1 : 2 Hence, the answer is option [3]. 126. [4]
One number from each ring can be chosen in 10 ways.
Since there are 3 rings, number of ways of choosing = 10 × 10 × 10 = 1000 Out of this there is one way in which the lock can be opened
Number of cases in which the lock cannot be opened = 1000 - 1 = 999. Hence, the answer is option [4].

If the person buys A class ‘I’ and B class ‘II’ tickets, then 10A + 3B = 110 ………. (1) 10B + 3A = x………. (2) On adding; 13(A+B) = 110 + x Now, A + B = 18 x = 234 - 110 = 124
Hence, the answer is option [4]. 128. [2]
From 7.25 pm to 7.25 am (12 hours) From 7.25 am to 1.25 pm (6 hours) From 1.25 pm to 1.45 pm (20 minutes) Total time passed is 18 hours 20 minutes In 24 hours, lag = 12 minutes
In 1 hour, lag = 12/24 minutes = ½ minutes In 18 hours, lag = ½ ×18 = 9 minutes In 60 minutes lag = 30 seconds In 20 minutes lag = 10 seconds
Lags by 9 minutes 10 seconds at 1:45 it will show 1 : 35 : 50. Hence, the answer is option [2]. 129. [2]
Originally positions of A and B are a and b New position of A is a'
Total person = 19 = (10 + 1 + 8) Hence, the answer is option [2]. 130. [1]
Let Cp = Rs. 100
Let us suppose 1000 gms → Rs. 100 of the food grain Case I. profit 30%
If Cp = 100 ; Sp = 130
Total profit in percentage = 30% Case II. Increase price by 15%
So selling price will be = 115, also weight will be reduced by 15%. That is 850 gms
So, 850 gms for Rs. 115
So, 1000 gms will be for Rs. 136 Total profit in percentage = 36%
Case III here use of 700 gms instead of 1000 gms So, 700 gms for Rs. 100
Therefore 1000 gms will be for Rs. 143 Total profit in percentage = 43%
No need to consider statement (IV) since it is not given in the options. Thus answer will be statement III.
Hence, the answer is option [1]. 131. [4]
From the given bar graphs, we can conclude about the reliability of different components as shown below.
Picture tubes > Signal devices > Capacitors > Integrated circuit > Printed circuit boards > Hybrid micro circuit
So, option [1] is not true.
Option [2] can be ruled out because picture tubes have more reliability than capacitors. Option [3] can be ruled out because higher number of component failures occurred because of hybrid micro circuit.
Now option [4] the least reliable component is hybrid micro circuits which is true. Hence, the answer is option [4].
132. [2]
Failure rate of signal device is 16. Thus, 25% of 16 = 4. Capacitor has failure rate of 20 which is 25% more than signal devices.
133. [3]
Failure rate of picture tubes and signal devices is less compared to other devices, thus the company will have the least priority to change.
Hence, the answer is option [3]. 134. [2]
The question is just asking that how much stock should be kept in the store. Integrated circuit board =
