P,Q and R are three cities,The ratio of average temperatures between P...


Analysis:

- Let the average temperatures of cities P, Q, and R be 11x, 12x, and 9y, respectively.
Ratio between P and Q:

- The ratio of average temperatures between P and Q is 11:12.
- Therefore, we have 11x/12x = 11/12, which simplifies to x = 12.
Ratio between P and R:

- The ratio of average temperatures between P and R is 9:8.
- Substituting the value of x, we get 11(12)/9y = 9/8.
- Solving this equation, we find y = 16.
Ratio between Q and R:

- The average temperatures of Q and R are 12x and 9y respectively.
- Substituting the values of x and y, we get (12*12)/(9*16) = 144/144 = 1.
- Therefore, the ratio between the average temperature of Q and R is 1:1, which is equivalent to 22:22.
Conclusion:

- The correct answer is none of these (d) as the ratio between the average temperature of Q and R is 1:1, not 22:27, 27:22, or 32:33.

Read the following passage and answer the items that follow the passage. Your answers to these items should be based on this passage only.PassageRecent findings show that changing climate patterns will affect the picturesque region in several ways. The most obvious one- assessed by analysing temperature data over the last 35 years from 11 meteorological stations in seven states across the region- is an increase in the occurrence of warm nights. This trend is likely to worsen, according to computer based climate models that were used to predict future climate trends. According to recent research exercises conducted at the Centre forAtmospheric Sciences at IIT Delhi., there has even been a rise of about two degrees, huge by climate change standards, in the average might time temperature between 1971 and 2005. The annual mean temperature over northeast India also displays a markedly upward trend.An increase in the frequency and intensity of warm nights does not just mean discomfort for local communities used to temperatures that range from cool to cold after sunset over the course of the year. Such warming has far more serious ramifications. As Dash puts it. We have not assessed the impact ofwarm events on biodiversity. But we can say that the ecosystem, including the glaciers in the region, could be affected by the temperature rise.Communities in the North eastern states are realising what the fallout of such change means, but in different ways. The fact that the temperature is increasing is being felt for the past 2 decades. But the trends vary in different regions. I think the impact is slightly more intense in the Northeast region than other parts of India. Even though there are several scientific studies based on different computer models, their predictions are different from each other. The community though, has a consensus on certain trends that they are experiencing, says Partha Das osAranyak, an environmental NGO in Guwahati.Three trends are clear; an overall warming across all seasons; heat waves in summer; and shrinking winters. In Meghalaya, for one, such climate is gradually being registered. B.K. Tiwari of the Northeastern Hill University conducted a study on peoples perception of climate change in the region a few years ago. But the responses were not conclusive. There was a consensus only on 1 aspect; most people agreed that extreme weather events like floods have become more frequent. But these perceptions have no scientific backing. They are just peoples assessments. So I think relying on the IMD data of at least 30 years is a morepractical method of understanding climate change. He saysConsider the following statements1. Changing climate patterns will strip the Northeastern states of their picturesque beauty.2. The average right time temperature will continue to grow at a rate of 10 per cent per decade.Q.What does the author mean when he states that communities in the Northeast are realising, in different ways, the fallout of climate change?
