Directions: The distance between two points A and B is 3500 m. Two policemen posted at points A and B got a news that a thief is located at point C which is located between A and B. The point C is at 500 m from the point A. Both policemen start at same time to catch the thief. When the policemen P1 approaches towards the thief, the thief sees him and starts running in opposite direction. Again, when he sees policemen P2 is also approaching towards him, he again changes his direction and now runs in opposite direction. He does so till the distance between policemen P1 and policemen P2 becomes less than 500 m and stop at that point when the distance between policemen P1 and P2 becomes 500 m to surrender. The thief had a distant vision of 200 m (or can see distant object clearly upto 200 m). The ratio of speed of policemen P1 and thief is 5 : 6 and the ratio of speed of policemen P1 and policemen P2 is 5 : 4. The speed of policemen P2 is 8 m/s

Question:  Find which policemen will catch the thief earlier and the total time taken to catch him. 

P1, 159 sec

 P2, 120 sec

 P1, 102.33 sec 

P2, 130.66 sec

 Both will catch him at same time 

Any Shortcut or Trick ?

RC Practice - 6th May 2020 : Geology


In choosing a method for determining climatic conditions that existed in the past, paleoclimatologists invoke four principal criteria. First, the material—rocks, lakes, vegetation, etc.—on which the method relies must be widespread enough to provide plenty of information, since analysis of material that is rarely encountered will not permit correlation with other regions or with other periods of geological history. Second, in the process of formation, the material must have received an environmental signal that reflects a change in climate and that can be deciphered by modern physical or chemical means. Third, at least some of the material must have retained the signal unaffected by subsequent changes in the environment. Fourth, it must be possible to determine the time at which the inferred climatic conditions held. This last criterion is more easily met in dating marine sediments, because dating of only a small number of layers in a marine sequence allows the age of other layers to be estimated fairly reliably by extrapolation and interpolation. By contrast, because sedimentation is much less continuous in continental regions, estimating the age of a continental bed from the known ages of beds above and below is more risky.

One very old method used in the investigation of past climatic conditions involves the measurement of water levels in ancient lakes. In temperate regions, there are enough lakes for correlations between them to give us a reliable picture. In arid and semiarid regions, on the other hand, the small number of lakes and the great distances between them reduce the possibilities for correlation. Moreover, since lake levels are controlled by rates of evaporation as well as by precipitation, the interpretation of such levels is ambiguous. For instance, the fact that lake levels in the semiarid southwestern United States appear to have been higher during the last ice age than they are now was at one time attributed to increased precipitation. On the basis of snow-line elevations, however, it has been concluded that the climate then was not necessarily wetter than it is now, but rather that both summers and winters were cooler, resulting in reduced evaporation.

Another problematic method is to reconstruct former climates on the basis of pollen profiles. The type of vegetation in a specific region is determined by identifying and counting the various pollen grains found there. Although the relationship between vegetation and climate is not as direct as the relationship between climate and lake levels, the method often works well in the temperate zones. In arid and semiarid regions in which there is not much vegetation, however, small changes in one or a few plant types can change the picture dramatically, making accurate correlations between neighboring areas difficult to obtain.


1. Which of the following statements about the difference between marine and continental sedimentation is supported by information in the passage?

(A) Data provided by dating marine sedimentation is more consistent with researchers’ findings in other disciplines than is data provided by dating continental sedimentation.

(B) It is easier to estimate the age of a layer in a sequence of continental sedimentation than it is to estimate the age of a layer in a sequence of marine sedimentation.

(C) Researchers are more often forced to rely on extrapolation when dating a layer of marine sedimentation than when dating a layer of continental sedimentation.

(D) Marine sedimentation is much more continuous than is continental sedimentation.


2. Which of the following statements best describes the organization of the passage as a whole?

(A) The author describes a method for determining past climatic conditions and then offers specific examples of situations in which it has been used.

(B) The author discusses the method of dating marine and continental sequences and then explains how dating is more difficult with lake levels than with pollen profiles.

(C) The author describes the common requirements of methods for determining past climatic conditions and then discusses examples of such methods.

(D) The author describes various ways of choosing a material for determining past climatic conditions and then discusses how two such methods have yielded contradictory data.


3. It can be inferred from the passage that paleoclimatologists have concluded which of the following on the basis of their study of snow-line elevations in the southwestern United States?

(A) There is usually more precipitation during an ice age because of increased amounts of evaporation.

(B) There was less precipitation during the last ice age than there is today.

(C) Lake levels in the semiarid southwestern United States were lower during the last ice age than they are today.

(D) The high lake levels during the last ice age may have been a result of less evaporation rather than more precipitation.


4. Which of the following would be the most likely topic for a paragraph that logically continues the passage?

(A) The kinds of plants normally found in arid regions

(B) The effect of variation in lake levels on pollen distribution

(C) A third method for investigating past climatic conditions

(D) Other criteria invoked by paleoclimatologists when choosing a method to determine past climatic conditions.

(B) provide an example of the uncertainty involved in interpreting lake levels

(C) prove that there are not enough ancient lakes with which to make accurate correlations

(D) explain the effects of increased rates of evaporation on levels of precipitation


6. It can be inferred from the passage that an environmental signal found in geological material would not be useful to paleoclimatologists if it

(A) had to be interpreted by modern chemical means

(B) reflected a change in climate rather than a long-term climatic condition

(C) was incorporated into a material as the material was forming

(D) also reflected subsequent environmental changes 

 

RC Practice - 7th May : Economics  

According to Rubina Verma, while the Indian economy has been shifting from being predominantly agriculture employment-based to one where the employment is a mix of agriculture, manufacturing and services, the economy has largely seen a "jobless growth" between the 1980s and 2007. This jobless growth in the Indian manufacturing has been puzzling, states Sonia Bhalotra, and is in part linked to the productivity growth. The major industries that have seen growth in formal employment have been export-oriented manufacturing, software, and local services. However, states Ajit Ghose, the services-based industry has not been "particularly employment-intensive", and its rapid growth has not addressed the unemployment and under-employment problems in India – and the job needs of its growing population – between 1983 and 2010. 

While new census data reveals that unemployment numbers are even direr than was previously suspected, it is not clear that the forecast for Indian entrepreneurship is equally alarming. An article in a major national newspaper suggests that the contraction in hiring at existing companies might result in more new companies being founded. College graduates, unable to find traditional jobs, instead opt to start their own businesses. Where a recession may seem an unpropitious time for such a historically risky endeavor, with no better options, would-be entrepreneurs have little to lose. 

Unfortunately, this situation does not necessarily impact the economy positively. Though the average number of new businesses started per year has been higher during the recession than it was before, the proportion of high-value businesses founded each year has declined. So even if a business manages to stay solvent, it may not bring significant returns. Also, because of an inevitable dearth of angel investors and venture capitalists, many new entrepreneurs are putting their own money on the line. In certain ways, the choice between accepting a traditional job and starting a business is not unlike the choice between renting and buying property. The latter requires a significant initial outlay and carries heavier risks, but sure the rewards can be equally substantial.

1. The primary purpose of the passage is to

(A) maintain that college students should form their own companies, especially during economic recessions

(B) argue that the Indian economy in the past has registered jobless growth 

(C) present a nuanced view of a contemporary economic issue

(D) evaluate the viability of low-versus high-value businesses under various environmental conditions

2. According to the passage, that many college graduates are choosing to launch their own companies in the present economic climate leads from

(A) the difficulty in finding outside (angel) investors

(B) the difficulty in landing positions typically open to workers of their experience

(C) an increase in the prevalence of low-value companies

(D) forecasts of the unemployment rates likely becoming less dire in coming years

3. It can be inferred from the passage that over the course of the recent recession, the number of Indian high-value businesses founded per year

(A) has fallen sharply

(B) has fallen moderately

(C) has risen sharply

(D) may have either fallen or risen

4. According to Sonia Bhalotra, the jobless growth in the Indian manufacturing sector

(A) has been consistent with decline in productivity 

(B) has resulted in growth in productivity

(C) can be attributed to a growth in productivity

(D) has been accompanied with a decline in growth rate of productivity

5. The author’s attitude towards the choice of starting a business over accepting a traditional job can best be regarded as 

(A) scepticism

(B) guarded encouragement

(C) dissuasion

(D) enthusiasm

at a certain stationary shop, the cost of each rules is 2.5 times the cost of each sharpener. Anil bought 25 rulers and a certain number of sharpeners. Had he bought as many rulers as the number of sharpeners that he bought and vice versa, his total expenditure on the two items would have been 9.09% less. How many sharpeners did he buy?
