Yes Bindu, You are right and thanks for correcting me.
and the right answer is 35 minutes.
Please find the logic and the program below:
int ppl , time , i , sum = 0;
printf("Enter the number of ppl u want to spread \r\n");
scanf("%d",&ppl);
while(sum<ppl)
{
sum = pow(3,i);
time = 5 * i;
i++;
}
printf("time in min required is %d \r\n",time);
[
out put:
Enter the number of ppl u want to spread
768
time in min required is 35
]
==================
For your refernce :
1->2 [ total 3 ppl ] took 5 min;
3 -> 6 [ total 9 ppl ] took 10 min
9 ->18 [ total 27 ppl ] took 15 min ..
27 -> 54 [ total 81 ppl ] took 20 min
81 -> 162 [ total 243 ppl ] took 25 min
243 -> 486 [ total 729 ppl ] took 30 min
729 -> 1458 [ total 2187 ppl ] took 35 min
overall it's power of 3

Answer / manish panwar
// It's a combination of 1+2+4+8+16+.... and each intervl
takes 5 minutes.
SO
1+2+4+8+16+32+64+128+256+512+1024
11*5 = 55 MINTS IN TOTAL .

Answer / bindu
In the first 5 mins three people come to know of the
rumour; including the first person (who is still able to
spread the rumour!), i..e every 5 mins, three times the
people come to know of the rumour. So it just takes 30 mins
for 729 people and 35 mins for 2187 people to know of the
rumour.

Answer / bindu
But Pradeep, your logic assumes that the people who have
already passed the rumour in the first 5mins, will not pass
it again in the next 5mins!! In my logic, they keep on
passing it; 1.e. they don't stop after the first time.

Answer / usha
Its 45 min becoz the Ist person spreeds rumour to 2person in
5 min. so in next 5 min the 2 person spreads simultaneously
to 4pesons and these steped is continued tel 45min, such as
2+4+8+16+32+64+128+256+512 this indicate at each addition it
take 5min. so the answer is 45min

Answer / pradeep
It requires 45 minutes:
Find the logic below:
int time;
for ( int i=0,SpreadRate=1,Ppl=0;Ppl<=768;i++)
{
Ppl = Ppl + SpreadRate;
time = 5 * i;
SpreadRate = SpreadRate * 2;
}
printf("time in min %d \r\n"),time);

Answer / pradeep
// It's a combination of 1+2+4+8+16+.... and each intervl
takes 5 minutes.
so use the below logic to find out the ryt answer
int time;
for ( int i=0,sum=0;sum<=768;i++)
{
sum = sum+(2*i);
time = 5*i;
}
printf("time in min %d \r\n"),time);
correct answer is 140 minutes [ nothng but 2 hours 20 min]
return TRUE;

The rich analysts of Fernand Braudel arid his fellow Annales historians have made significant contributions to historical theory and research. In a departure from traditional historical approaches, the Annales historians assume (as do Marxists) that history cannot be limited to a simple recounting of conscious human actions, but must be understood in the context of forces and material conditions that underlie human behavior. Braudel was the first Annales historian to gain widespread support for the idea that history should synthesize data from various social sciences, especially economics, in order to provide a broader view of human societies over time (although Febvre and Bloch, founders of the Annales school, had originated this approach). Braudel conceived of history as the dynamic interaction of three temporalities. The first of these, the evenmentielle, involved short-lived dramatic events such as battles, revolutions, and the actions of great men, which had preoccupied traditional historians like Carlyle. Conjonctures was Braudel’s term for larger cyclical processes that might last up to half a century. The longue duree, a historical wave of great length, was for Braudel the most fascinating of the three temporalities. Here he focused on those aspects of everyday life that might remain relatively unchanged for centuries. What people ate, what they wore, their means and routes of travel—for Braudel these things create “structures’ that define the limits of potential social change for hundreds of years at a time. Braudel’s concept of the longue duree extended the perspective of historical space as well as time. Until the Annales school, historians had taken the juridical political unit—the nation-state, duchy, or whatever—as their starting point. Yet, when such enormous timespans are considered, geographical features may well have more significance for human populations than national borders, In his doctoral thesis, a seminal work on the Mediterranean during the reign of Philip II, Braudel treated the geohistory of the entire region as a “structure” that had exerted myriad influences on human lifeways since the first settlements on the shores of the Mediterranean Sea. And so the reader is given such arcane information as the list of products that came to Spanish shores from North Africa, the seasonal routes followed by Mediterranean sheep and their shepherds, and the cities where the best ship timber could be bought. Braudel has been faulted for the imprecision of his approach. With his Rabelaisian delight in concrete detail, Braudel vastly extended the realm of relevant phenomena but this very achievement made it difficult to delimit the boundaries of observation, a task necessary to beginning any social investigation. Further, Braudel and other Annales historians minimize the differences among the social sciences. Nevertheless, the many similarly designed studies aimed at both professional and popular audiences indicate that Braudel asked significant questions that traditional historians had overlooked. 14) The primary purpose of the passage is to: a) show how Braudel’s work changed the conception of Mediterranean life held by previous historians. b) evaluate Braudel’s criticisms of traditional and Marxist historiography. c) contrast the perspective of the longue duree with the actions of major historical figures d) outline some of Braudel’s influential conceptions and distinguish them from conventional approaches. 15) The author refers to the work of Febvre and Bloch in order to: a) illustrate the limitations of the Annale tradition of historical interpretation. b) suggest the relevance of economics to historical investigation. c) debate the need for combining various sociological approaches. d) show that previous Annales historians anticipated Braudel’s focus on economics. 16) According to the passage, all of the following are aspects of Braudel’s approach to history EXCEPT that he: a) attempted to draw on various social sciences. b) studied social and economic activities that occurred across national boundaries. c) pointed out the link between increased economic activity and the rise of nationalism. d) examined seemingly unexciting aspects of everyday life. 17) In the third paragraph, the author is primarily concerned with discussing: a) Braudel’s fascination with obscure facts. b) Braudel’s depiction of the role of geography in human history. c) the geography of the Mediterranean region. d) the irrelevance of national borders. 18) The passage suggests that, compared with traditional historians, Annales/i> historians are: a) more interested in other social sciences than in history. b) critical of the achievements of famous historical figures. c) skeptical of the validity of most economic research. d) more interested in the underlying context of human behavior. 19) Which of the Following statements would be most likely to follow the last sentence of the passage? a) Few such studies however, have been written by trained economists. b) It is time, perhaps, for a revival of the Carlylean emphasis on personalities. c) Many historians believe that Braudel’s conception of three distinct “temporalities” is an oversimplification. d) Such diverse works as Gascon’s study of Lyon and Barbara Tuchman’s A Distant Mirror testify to his relevance. 20) The author is critical of Braudel’s perspective for which of the Following reasons a) It seeks structures that underlie all forms of social activity. b) It assumes a greater similarity among the social sciences than actually exists. c) It fails to consider the relationship between short-term events and long-term social activity. d) It rigidly defines boundaries for social analysis.
