Question : The value of $\frac{1}{8} × \left[\frac{1}{5}\right.$ of $\left.\frac{11}{2} ÷\left\{\left(\frac{15}{3}-\frac{18}{6}\right)\right\}\right]$ is:
Option 1: $\frac{11}{160}$
Option 2: $\frac{11}{20}$
Option 3: $\frac{8}{11}$
Option 4: $\frac{11}{8}$
Correct Answer: $\frac{11}{160}$
Solution : Given expression, $\frac{1}{8} × \left[\frac{1}{5}\right.$ of $\left.\frac{11}{2} ÷\left\{\left(\frac{15}{3}-\frac{18}{6}\right)\right\}\right]$ $=\frac{1}{8}\times[\frac15\text{ of }\frac{11}{2}÷\{5-3\}]$ $=\frac{1}{8}\times[\frac{11}{10}÷2]$ $=\frac{1}{8}\times\frac{11}{20}$ $=\frac{11}{160}$ Hence, the correct answer is $\frac{11}{160}$

Question : Comprehension: Read the following passage and answer the questions given after it. The severe cyclonic storm, Nisarga, which made landfall south of Alibag in Maharashtra’s Raigad district on Wednesday at 11.30 a.m. is an indication of an increasing frequency of severe cyclones developing in the Arabian Sea in the past decade, a trend that studies have linked to climate change. In the past two years, there have been seven cyclones in the Arabian Sea, though, according to the India Meteorological Department (IMD), the ratio of cyclones in the Arabian Sea and the Bay of Bengal — which just witnessed the destructive cyclone Amphan on May 21 — is 1:4. The Intergovernmental Panel on Climate Change (IPCC) last year came out with a special report, Ocean and Cryosphere in a Changing Climate, in which it said that extreme rainfall and extreme sea level events associated with some tropical cyclones are being seen to have a cascading impact on coastal areas. “There is emerging evidence for an increase in the annual global proportion of Category 4 or 5 tropical cyclones in recent decades,” the IPCC report had said. A category 4 cyclone has a wind speed of 209-251 kmph, and is referred to as an extremely severe cyclonic storm, while a category 5 cyclone has a wind speed of more than 252 kmph, and is referred to as a super cyclone. The IPCC report refers to a 2017 study led by the Atmospheric and Oceanic Sciences Program, Princeton University, USA, which found that in 2014 and 2015, post-monsoon extremely severe cyclonic storms (ESCS) were first observed over the Arabian Sea causing widespread damage. The study had concluded that climate change had led to an increase in the occurrence of ESCSs in the Arabian Sea.“Our research suggests that cyclones would be more frequent during the post-monsoon season (October-December) by a series of climate model simulations. However, we didn’t find any significant changes in cyclone activity during the pre-monsoon (April-June) season through the climate simulations. It is very difficult to identify if a cyclone (like Nisarga) is generated in line with climate change,” said Hiroyuki Murakami, the lead author of the study. “Coastal hazards will be exacerbated by an increase in the average intensity, magnitude of storm surge, rising mean sea levels and precipitation rates of tropical cyclones,” the IPCC report further stated. Question: The passage is mainly focused on:
Option 1: the research on super cyclones
Option 2: the effect of climate change on cyclone Nisarga
Option 3: the frequency of cyclones in the Arabian Sea and Bay of Bengal
Option 4: the link of frequent cyclones with climate change
Correct Answer: the link of frequent cyclones with climate change
Solution : The right choice is the fourth option.
Explanation: The passage highlights how climate change is linked to a rising number of severe cyclones in the Arabian Sea. It cites a specific cyclone, Nisarga, as an example.
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at (1), (2), and (3) that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).

Option 3: (3)
Option 4: (4)
Correct Answer: (3)

Question : Three numbers are such that their sum is 50, the product is 3750 and the sum of their reciprocals is $\frac{31}{150}$. Find the sum of the squares of the three numbers.
Option 1: $2500$
Option 2: $1250$
Option 3: $950$
Option 4: $122$
Correct Answer: $950$
Solution : Let the numbers be $a, b$ and $c$. Given: $(a + b + c) = 50$, $abc = 3750$ and $\frac{1}{a} + \frac{1}{b} + \frac{1}{c} = \frac{31}{150}$ Now, $\frac{1}{a} + \frac{1}{b} + \frac{1}{c} = \frac{(bc + ac + ab)}{abc}$ ⇒ $\text{(bc+ac +ab)} = \frac{31}{150}\times 3750
