Directions: Read the given information carefully and answer the question that follows.
Given below is a network of high tension wires from power plant (PP) and 8 transformers T1 to T8. The requirement of power by transformer is exactly met by the electric power provided by the power plant. The electric power in some of the high tension wires and the requirement at some of the transformers has also been mentioned. PP is the source transformer, i.e. the PP does not have any requirement of its own, but it supplies the requirements of all the other transformers.(All values shown in the figure are in KW.)
 
It is also known that: 
i. The maximum capacity of any high tension wire is 1000 KW.
ii. The requirement at any transformer, except the power plant and T8, is equal to the flow in exactly one of the high tension wires directly connected to it.
iii. No two high tension wires, directly connected to the same transformer, carry the same amount of electric power.
iv. The flow in none of the high tension wires shown above is zero.

  • a)
    100
  • b)
    300
  • c)
    400
  • d)

Directions: Read the given information carefully and answer the questi...
As no two high tension wires connecting the same place are carrying same amount of electric power, and at least one of the high tension wires should carry same as that of the place, either T7-T8 or T6-T7 must carry 300 kW. If T6-T7 carries 300kW, then T7-T8 must carry 200 kW, which is not possible.
T7-T8 must carry 300 kW and T6-T7 must carry 400 kW. T3-T6 should carry 400 kW more than the requirement at T6.
T6's requirement must equal that of T6-T7.
Requirement at T6 = 400
T3-T6 = 800
The flow in T4-T8 must be equal to the requirement at T4, and each of them must be equal to 100. Therefore, the requirement at T8 = 100 + 300 = 400.
Considering T5, the flow in T5-T1 must be equal to the requirement at T5, i.e. 100, and the flow in T5-T2 must be 100 + 100 + 200 = 400 (balancing the flows at T5).
Now balancing the flows at T1, T1-T2 must be equal to the requirement at T2, i.e. 300.
Now, to meet the conditions at transformer T2, the flow in exactly one out of PP-T2 and T3-T2 must be equal to the requirement at T2, i.e. 200, and the other must be 100.
Now considering T3, the maximum capacity of PP-T3 is 1000.
T3 cannot be more than 100, as then, PP-T3 will be more than 1000.
T3 must be 100 and T3-T2 must be 100.
PP-T3 is 1000.
Hence, the final diagram will be as below:

Hence, 400 kW is carried by the high tension wire T2-T5.

Read the passage carefully and answer the following questions:It’s tempting to think that viral misinformation is a modern invention of social media and malicious actors. In fact, “fake news” is as old as news itself. For centuries, falsehoods have been shared widely as facts and stood uncorrected for months or years, even becoming accepted truth. Many of these stories were consequence-free, such as the widely believed report in 1569 of a Leicestershire woman who was “confirmed” to have given birth to a cat. Others led to tragedy and horror, such as viral rumors that the Black Plague was caused by Jews poisoning wells, which led to executions and violent pogroms throughout EuropeRegardless of the era, rumors and falsehoods spread via two basic steps: discovery, then amplification of unverified knowledge. What’s different now is that today’s communication platforms have fundamentally transformed the way information flows, propelling viral rumors exponentially faster and farther than ever. Widespread belief in certain types of viral rumors poses a threat to institutions that we rely on, including democracy itself. An urgent question has emerged: How can we mitigate the kind of high-consequence misinformation that’s increasingly plaguing our communication ecosystem? Friction, a system of checks to limit the spread of content, we believe, is the answer.Before the printing press, viral rumors spread through word-of-mouth chatter in the market square or pub. Still, businesspeople, rulers, and religious authorities required trustworthy knowledge, and they would spend enormous sums on timely, accurate news. For those under their employ, the earliest proto-journalists, sourcing truth was a constant struggle. Newsmen added “friction” to the process of sharing knowledge, painstakingly validating stories through second- and third-hand sources before they published—lest they lose their reputation and sponsors. This tension between speed and accuracy came to define early news reporting. News that was both timely and accurate was incredibly expensive, requiring verified couriers and messengers, known as postal systems. We can still see this holdover in the title of “post” in many newspaper names today.Early journalists were far from perfect, and many of the first newspapers competed for attention by aggressively peddling false, outrageous, or nakedly partisan stories, gruesome crime coverage in particular. But during the 19th century, some papers slowly matured and professionalized, building reputations for publishing factual narratives, and engendering trust as “objective” news sources. Through fits and starts, this patchwork system of news-gathering and distribution became the dominant way we empirically verify information before amplifying it. We learned to trust journalists, largely because they fact-check rumors.The internet—and social media in particular—blew the system of journalistic friction to pieces. First the internet transformed publishing. Blogging platforms enabled anyone to publish whatever, whenever, without the critical eye of a journalistic colleague. Publishing was now a democratized, zero-cost endeavor. When the social networks emerged, distribution and reach were also transformed. Hundreds of millions of people found themselves perpetually online in new, targetable, frictionless communities. Groups became digital gathering places for ordinary people, and not gatekeepers, to share information. The single-click Share button turned people into active participants in the distribution and amplification of information.Reduced friction has enabled important new voices to be heard, but it has also led to the rapid spread of significantly impactful viral misinformation. Hence, It’s time for proactive solutions; it’s time to reintroduce the sort of friction that can assist with collective sense-making.Q.Which of the following statements CANNOT be inferred from the passage?I. Ubiquitous access to the internet and social networking websites has led to the repudiation of established facts.II. Fear of losing their reputation and sponsors was one of the reasons that forced the earliest newsmen to filter out erroneous information scrupulously.III. People trust journalists not because they report accurate information but because they debunk rumours.IV. Misinformation campaigns could potentially amend the core values that define a democratic society.
