CAT 2003

Correct answer: B

The tone which author uses while asking “what French winemaker will ever admit that? is not at all harsh , so option a) is out . Also the author doesn't criticize while asking the question ,so Option c ) is clearly not the answer. We don't find any author professing any feelings which he doesn't have , hence the tone is not hypocritical. Option b ,suits the best i.e. his tone is satirical.

Correct answer: A

Refer to the part of the passage which says ' ...not because they think their wine isn’t as good as the best from California ...and they aren’t about the change...probably no other way if France is to avoid simply becoming a specialty source of old-fashioned wines for oldfashioned connoisseurs. ' . From this, we can see that the author feels that the French should adopt the labeling strategy of the English-speaking countries to avoid becoming a producer of merely old-fashioned wines. Option a) is the correct answer.

Correct answer: B

Consider the following part of the passage ' .. Consumer effectively recognize them as brand names, and have acquired a basic lexicon of wine .... with those Brazilian upstarts. In the wine heartlands of France, they are scared to death of that trend.. '. So, above all, French winemakers fear the knowledge or education that the consumers have derived from wine labels from the English speaking countries. Option b) is the correct answer.

Correct answer: D

Dr. Renaud findings suggest that fat-derived cholesterol can be dispersed by the tannins in wine. So, a survey that validates this finding would provide the most support. The survey in option d) is precisely one such survey. Option d) is the correct answer.

Correct answer: C

Consumers' appreciation of better quality wines is something that does not come because of the labeling or branding. So, this appreciation cannot be attributed to the labeling strategy followed by wine producers in English speaking countries. Option c) is the correct answer.

Correct answer: C

Consider the following lines from the passage: "But he was overruled by Indian hands who said India would resist payment and paralyse the war effort". From this, we can understand the reason why the British didn't tax India to finance its war efforts. It was afraid that if India refused to pay, Britain's war efforts would be jeopardized. Option c) is the correct answer.

Correct answer: C

Refer to the 5th paragraph. It says "Though crushed, it reminded the British vividly that they were a tiny ethnic group who could not rule a gigantic subcontinent without the support of the important locals". From this, we can understand that the main lesson that the British learnt from the Sepoy Mutiny of 1857 was that they were a small ethnic group. Option c) is the correct answer.

Correct answer: B

If the returns from conquest decreased and the costs increased, it wouldn't make sense to continue empire-building in India. So, the sentence in option b) is not a reason for the emergence of the 'white man's burden' as a new rationale for empire-building in India.

Correct answer: A

White man's burden refers to the claim made by the British that the natives of the conquered countries were in need of the 'good' provided by them. This was a justification for their conquests. Option a) captures this idea succinctly.

Correct answer: D

Throughout the passage, the author talks about the various financial reasons for conquest and explains how the British were forced to grant independence when their returns from India diminished after the war. The main idea of the passage is to illustrate how the erosion of the financial basis of an empire supports the granting of independence to an empire's constituents. Option d) is the correct answer.

Correct answer: C

By the line "Even if the research promoted by them ................... in both developing and developed countries", we can say that not only MNCs but also governments are involved in the research development. So, MNCs are not the only group actors that are involved in genetically modified food research. Hence, option C is the answer.

Correct answer: C

According to the passage, European nations are anti GM. So, among the given options we must select those countries that are present in Europe. USA is not in Europe => option A is wrong. India is not in Europe => option B is wrong. Australia is not in Europe => option D is wrong. Both Germany and France are in Europe => option C is the answer.

Correct answer: B

Refer to the last lines of the passage:"However, some weeds through genetically-modified pollen contamination may acquire resistance to a variety of weed-killers. The only way to destroy these weeds is through the use of ever-stronger herbicides which are poisonous and linger on in the environment." This line indicates the point made in 2 that once the weeds acquire resistance to weak herbicides, we have to apply stronger ones to eradicate them.

Correct answer: D

Refer to the lines made in the paragraph:"Even if the research promoted by them does focus on the high-value food items, much of biotechnology research is also funded by governments in both developing and developed countries. Indeed, the protato is a by-product of this type of research. If the protato passes the field trials, there is no reason to believe that it cannot be marketed in the global potato market. And this type of success story can be repeated with other basic food items." Here the author wants to illustrate that biotechnology resarch helps to address the concerns of the developing countries. For this illustration, the author gives the exmaple of potatoes.

Correct answer: A

Refer to the following lines in the passage:"It is quite likely that the GM controversy will soon hit the headlines in India since a spokesperson of the Indian Central government has recently announced that the government may use the protato in its midday meal programme for schools as early as next year. Why should “scientific progress”, with huge potential benefits to the poor and malnourished, be so controversial?" Here the author wants to highlight that the scientific progress which has a huge impact on large number of people is likely to be covered by the media.

Correct answer: A

Refer to the last lines of the second paragraph:"These large gatherings will be only what we make of them if not anything better, they can be as good places to collect new friends from as the slavemarkets of Istanbul were for beautiful slaves or New Market for race horses." Here "They" refers to the large gatherings of casual acquaintances as illustrated in these lines.

Correct answer: C

The passage starts with the author's perception of social life. In the whole passage the author criticises the fact that we do not possess any social life. The author also gives his opinions of social life and then moves on to lament our little social life we have left. Option b and d are not clearly the main subject of the author. Option a is inappropriate as the author do not highlight our real social life but rather complaints of the social life.

Correct answer: B

The author's conception of social life is mentioned in the fourth paragraph where he says wonder and interest. Hence B is the correct answer.

Correct answer: A

The author is trying to say that people are not able to recognize the passionate attitude. So, the word "discriminate" in this context means "recognize".

Correct answer: C

In the second line after the line mentioned in the question, the author says that "the feeling was general that all the physical processes of nature would prove to be unfolding themselves according to the rigourous mathematic laws". Option C is the answer.

Correct answer: B

The author says that "The next advance was due to Newton, the greatest scientist of all time if account be taken of his joint contributions to mathematics and physics." Joint contributions is metaphorically said as married in option B. Hence, option B is the answer.

The author says that Einstein's principle is merely an extension of classical Newtonian principle. Option D agrees with this saying that new knowledge about natural phenomena builds on existing knowledge. Hence, option D is the answer.

Correct answer: C

The author says that "Its SIGNIFICANCE lay in its assertion that absolute Galilean motion or absolute velocity must ever escape all experimental detection." Here, "it" refers to Einstein's principle. The meaning of the sentence is that it is not always possible to experiment. Option C gives a similar meaning. Hence, C is the answer.

Correct answer: B

Correct answer: A

Option A gives the big picture of why the poet recommends a long journey. The remaining options are short-sighted and the poet was not much concerned about them.

Correct answer: D

The whole poem was about the goal and the journey to reach the goal. If we see the lines "Better if it lasts for years ............. not expecting Ithaka to make your rich", we can see that the poet is comparing Ithaka to life's distant goal. Option D is the answer.

Correct answer: C

The poet is trying to say that one who pursues the journey to one's goal must not be afraid of hindrances in that journey. Option C is similar to our conclusion. Hence, option C is the answer.

The success rate of moving from written test to interview stage for males in 2003 can be given by 637/60133 and for females in the same year can be given by 399/40763 . We can see that the rate of males is clearly more that that of females. hence statement A is false. Now the success rate of moving from written test to interview stage for females in 2002 was 138/15389 and for females in the year 2003 was 399/40763.So the rate in 2002 is less than that in 2003. . Hence both statements are false.

Correct answer: D

In 2002, the number of females selected for the course as a proportion of the number of females who bought application forms was 48/19236 and for males was 171/61205. So rate for males was higher than that of female. Hence option A is false. In 2002, among those called for interview, the success rate for females was 48/138 and for males 171/684. So the rate was higher for females .Both are false. Hence option D.

Correct answer: A

The percentage of absentees in the written test among females in 2002 was 3847/19236 and in 2003 was 4529/45292. Thus percentage of absentees decreased from 02 to 03. Hence statement A is true. The percentage of absentees in the written test among males in 2003 is 3065/63298 which is clearly less than that of female in 2003. Hence statement b is false . Hence option A.

Correct answer: B

From the given statements, we can infer that the amounts spent by the women are Rs.2234, Rs.1193, Rs.1340, and Rs.2517. Also, we know that one of the 5 women spent Rs.1378 more than Chellamma. Also, we know that each woman spent at least Rs.1000. The person who spent Rs.2234 cannot be the person who spent Rs.1378 more than Chellamma. Also, we know that Chellamma spent the least among the five women. Case 1: Chellamma spent Rs.1193. => One of the 5 women spent 1193+1378 = Rs.2571. We know that Shahnaz spent the most. Therefore, Shahnaz should have spent Rs.2571. Archana didn't spend Rs.2517. Also, Helen spent more than Dhenuka. Therefore, Helen should have spent Rs.2517. Dhenuka didn't spend Rs.1340. Therefore, Dhenuka should have spent Rs. 2234 and Archana should have spent Rs.1340. However, it has been given that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. According to the given order, Archana arrived before Dhenuka. Therefore, we can eliminate this case. Case 2: Rs.2517 is the highest amount spent. Shahnaz spent Rs.2517. => Amount spent by Chellamma = 2517 - 1378 = Rs.1139 Dhenuka didn't spend Rs.1340. Helen spent more than Dhenuka. Therefore, Dhenuka should have spent Rs.1193. Now, we know that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. Helen did not arrive before Dhenuka but Archana did. Therefore, Archana should have spent Rs.2234 and Helen should have spent Rs.1340.

According to given conditions amount spent by everyone is,

Hence, option B is the right answer.

Correct answer: A

From the given statements, we can infer that the amounts spent by the women are Rs.2234, Rs.1193, Rs.1340, and Rs.2517. Also, we know that one of the 5 women spent Rs.1378 more than Chellamma.

Also, we know that Chellamma spent the least among the five women. Case 1: Chellamma spent Rs.1193. => One of the 5 women spent 1193+1378 = Rs.2571. We know that Shahnaz spent the most. Therefore, Shahnaz should have spent Rs.2571. Archana didn't spend Rs.2517. Also, Helen spent more than Dhenuka. Therefore, Helen should have spent Rs.2517. Dhenuka didn't spend Rs.1340. Therefore, Dhenuka should have spent Rs. 2234 and Archana should have spent Rs.1340. However, it has been given that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. According to the given order, Archana arrived before Dhenuka. Therefore, we can eliminate this case. Case 2: Rs.2517 is the highest amount spent. Shahnaz spent Rs.2517. => Amount spent by Chellamma = 2517 - 1378 = Rs.1139 Dhenuka didn't spend Rs.1340. Helen spent more than Dhenuka. Therefore, Dhenuka should have spent Rs.1193. Now, we know that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. Helen did not arrive before Dhenuka but Archana did. Therefore, Archana should have spent Rs.2234 and Helen should have spent Rs.1340.

According to given conditions amount spent by everyone is,

Hence, option A is the right answer.

Correct answer: C

From the given statements, we can infer that the amounts spent by the women are Rs.2234, Rs.1193, Rs.1340, and Rs.2517. Also, we know that one of the 5 women spent Rs.1378 more than Chellamma. Also, we know that each woman spent at least Rs.1000. The person who spent Rs.2234 cannot be the person who spent Rs.1378 more than Chellamma. Also, we know that Chellamma spent the least among the five women. Case 1: Chellamma spent Rs.1193. => One of the 5 women spent 1193+1378 = Rs.2571. We know that Shahnaz spent the most. Therefore, Shahnaz should have spent Rs.2571. Archana didn't spend Rs.2517. Also, Helen spent more than Dhenuka. Therefore, Helen should have spent Rs.2517. Dhenuka didn't spend Rs.1340. Therefore, Dhenuka should have spent Rs. 2234 and Archana should have spent Rs.1340. However, it has been given that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. According to the given order, Archana arrived before Dhenuka. Therefore, we can eliminate this case. Case 2: Rs.2517 is the highest amount spent. Shahnaz spent Rs.2517. => Amount spent by Chellamma = 2517 - 1378 = Rs.1139 Dhenuka didn't spend Rs.1340. Helen spent more than Dhenuka. Therefore, Dhenuka should have spent Rs.1193. Now, we know that the woman who spent Rs. 2234 arrived before the lady who spent Rs. 1193. Helen did not arrive before Dhenuka but Archana did. Therefore, Archana should have spent Rs.2234 and Helen should have spent Rs.1340.

According to given conditions amount spent by everyone is,

Considering (i), Ignesh has to eat 6 vadas, since 6 is the only multiple of 3.

Also, using the same information, we can say that a person consumes 2 vadas and 4 idlis.

Using (vii), Bimal eats 2 more idlis than Ignesh.

Possibilities:

Bimal - 8, Ignesh - 6

Bimal - 6, Ignesh - 4

But Ignesh cannot have 4 idlis because the person who eats 4 idlis eats 2 vadas.

Hence we take Bimal - 8 and Ignesh - 6.

Let A , B and f,s be the distance traveled and speed of the fastest and the slowest person respectively. Also f=2s so in the given time A=2B. Since the ration of the speeds is 2:1, they will meet at 2-1 points = 1 pont. Both meet each other for first time at starting point . let b travel distance equal to 1 circumference i.e. 1000m so A=2000m . Both meet after 5 min so speed of slowest is 1000/5=200m/min . So speed of the fastest is 400m/min. So time taken by A to complete race 4000/400 = 10 min

Correct answer: A

Correct answer: D

Let $$\alpha $$ be equal to k. => f(x) = $$x^2-(k-2)x-(k+1) = 0$$ p and q are the roots => p+q = k-2 and pq = -1-k We know that $$(p+q)^2 = p^2 + q^2 + 2pq$$ => $$ (k-2)^2 = p^2 + q^2 + 2(-1-k)$$ => $$p^2 + q^2 = k^2 + 4 - 4k + 2 + 2k$$ => $$p^2 + q^2 = k^2 - 2k + 6$$ This is in the form of a quadratic equation. The coefficient of $$k^2$$ is positive. Therefore this equation has a minimum value. We know that the minimum value occurs at x = $$\frac{-b}{2a}$$ Here a = 1, b = -2 and c = 6 => Minimum value occurs at k = $$\frac{2}{2}$$ = 1 If we substitute k = 1 in $$k^2-2k+6$$, we get 1 -2 + 6 = 5. Hence 5 is the minimum value that $$p^2+q^2$$ can attain.

Let R ,r be radius of big and small circles respectively. We know that R=2r.

And since area = 12 ;

$$R^2 = \frac{12}{\pi}$$. $$r^2$$ = $$\frac{3}{\pi}$$

By pythagoras theorem in the small triangle with side 'x' we have x = $$\sqrt{\ 3}r$$.

Angle OAB = $$\tan\ \theta\ \ =\ \ \frac{\ r}{\sqrt{\ 3}r}\ =\ 30$$ Hence Angle CAB = 60.

So area = $$\ \frac{\ 1}{2}\ \times\ 2\sqrt{\ 3}r\times\ 2\sqrt{\ 3}r\times\ \sin\ 60$$. On substituting the value of sin 60 and $$r^2$$, we get Area = $$9\sqrt3/\pi$$.

Let R be radius of big circle and r be radius of circle with centre S. Radius of 2 semicircles is R/2.

From Right angled triangle OPS, using pythagoras theorem we get

$$(r+0.5R)^2 = (0.5R)^2 + (R-r)^2$$ . We get R=3r .

Now the area of big semicircle that cannot be grazed is Area of big S.C - area of 2 semicircle - area of small circle = $$\pi*R^2$$/2 - 2*$$\pi*(0.5R)^2$$/2-$$\pi*r^2$$ = $$\pi*R^2$$/2 - 2*$$\pi*(0.5R)^2$$/2-$$\pi*(R/3)^2$$= $$\pi*R^2$$/2 - $$\pi*(R)^2$$/4-$$\pi*(R)^2$$/9 = 5*$$\pi*R^2$$/36. this is about 28 % of the area $$\pi*R^2$$/2 . Hence option B.

Hence AP = $$b$$ ...(1)

$$\text{AC}^2 = \text{AB}^2 + \text{BC}^2$$

$$\text{AC}^2 = b^2 + b^2$$ => $$\text{AC} = \sqrt{2}\times b$$ => $$\text{AO} = \dfrac{\text{AC}}{2} = \dfrac{b}{\sqrt{2}}$$

$$\text{AP}^2 = \text{AO}^2 + \text{OP}^2$$

Take any 12 points. The maximum number of edges which can be drawn through these 12 points are $$^{12}C_2$$ = 66 The minimum number of edges which can be drawn through these 12 points are 12-1 = 11 as the resulting figure need not be closed. It might be open.

Correct answer: B

positive integers n in the range $$12 \leq n \leq 40$$ such that the product (n -1)*(n - 2)*…*3*2*1 is not divisible by n, implies that n should be a prime no. So there are 7 prime nos. in given range. Hence option B.

Correct answer: D

No. of terms in series T , 3+(n-1)*8 = 467 i.e. n=59. Now S will have atleast have of 59 terms i.e 29 . Also the sum of 29th term and 30th term is less than 470. Hence, maximum possible elements in S is 30.

Correct answer: A

Let a,d,j,g be the shots put by Ashish, Dhanraj, Ganesh and Jugraj respectively. According to given conditions we have , g = a-8; d + r = 37; j = d + 8; a = 5 + d; a + g = 40 Solving these equations, we have a = 24, d = 19 and j = 27 and r = 18. Hence option A is the correct answer.

Correct answer: C

We know that the total time taken is 1.5 hrs. Calculating the individual time taken and the adding and then equating to 1.5.

Let R be the radius of the outer-ring road.

$$\frac{\pi*R}{2*30*\pi} + \frac{\sqrt{5}*R}{2*15*\sqrt{5}}$$ = 1.5 solving we get R=30.

Correct answer: D

Let the radii of 2 circles be R and r respectively such that R=2*r. Triangle $$ON_2E_1$$ and all the other 3 similar triangles form a right angle at the centre. So, using Pythagoras theorem, the value of chords comes out to be $$\sqrt{\ 5}\times\ \dfrac{R}{2}$$ . Hence, the total distance travelled is $$\sqrt{\ 5}\times\ \dfrac{R}{2}$$ + $$0.5\ \times\ R\ \times\ \pi\ $$. The total time required can be calculated by distance/speed, which comes out to be 3.5 * R. Among options, only 105 is an integral multiple of 3.5.
