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:
Which of the following is a category 4 cyclone?

Option 1: One with a wind speed of 209–251 kmph

Option 2: One with a wind speed of less than 150 kmph

Option 3: One with a wind speed of more than 252 kmph

Option 4: One with a wind speed of 150-208 kmph

Solution : Given: 391 Boys and 323 Girls in the class.
Prime factors of 391 = (17 × 23)
Prime factors of 323 = (17 × 19)
HCF of (391, 323) = 17
The largest possible equal number of students in each class = 17

Question : From a solid cylindrical wooden block of height 18 cm and radius 7.5 cm, a conical cavity of the same height and radius is taken out. What is the total surface area (in cm2) of the remaining solid?

Option 1: $270 \pi$

Option 2: $416.25 \pi$

Option 3: $326.25 \pi$

Option 4: $472.5 \pi$

Team Careers360 23rd Jan, 2024

Correct Answer: $472.5 \pi$


Solution : According to the question
⇒ Area of base = πr2
Now,
⇒ Slant height, $l=\sqrt{h^{2}+r^{2}}=\sqrt{18^{2} + 7.5^{2}}=\sqrt{324 + 56.25}=\sqrt{380.25} = 19.5$
The curved surface of the cone = πrl  
= $π × 7.5 × 19.5$
= $146.25 π$
The surface area of the

Question : R wants to deposit Rs. 80,000 in the bank for a year. For his account, the bank gives 12% simple annual interest but charges Rs. 3,000 as a processing fee. What would be his percentage earnings in the account?

Option 1: 8.75%

Option 2: 9%

Option 3: 8.5%

Option 4: 8.25%

Team Careers360 23rd Jan, 2024

Correct Answer: 8.25%


Solution : Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
Simple interest on Rs. 80000 in 1 year at the rate of 12% $=\frac{80000 × 12 × 1}{100} = 9600$
The bank takes Rs. 3000 as a processing charge.
So, net profit for R = (9600 –
