UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 1

Arijit and Brajesh, working together, can complete a task in 10 days, whereas Brajesh and Chandan can finish the same job in 15 days working together. If Arijit works for 5 days and Brajesh works for 8 days, it takes Chandan 9 days to complete the rest of the task. How many days will Chandan take to finish the same job alone?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 1

Let us assume that working alone Arijit completes the task in ‘a’ days, Brajesh completes in ‘b’ days and Chandan completes in ‘c’ days.
1/a + 1/b = 1/10      ...........(1)
1/b + 1/c = 1/15 ............ (2)
It is also given that:
5/a + 8/b + 9/c = 1
Or 5(1/a + 1/b) + 3(1/b + 1/c) + 6/c = 1
Using (1) and (2),
5/10 + 3/15 + 6/c = 1
Or 6/c = 1 - ½ - 1/5 = 3/10
Or  c = 20.
Chandan can finish the task alone in 20 days.

Study the following information and answer the questions that follow: 


One pie chart shows the percentage distribution of the total number of students (Boys and Girls) enrolled for different activities in School A, and the other pie chart shows the percentage distribution of the total number of girls enrolled for different activities in School A.

Q. ​The total number of boy students enrolled in dancing and singing together is approximate what percentage of the total number of girl students enrolled for the same activities?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 2

The correct option is C.
Total no. of students enrolled for dancing = 2500*18/100 = 450
Total no. of students enrolled for singing = 2500*14/100 = 350
Total no. of girls enrolled for dancing = 1200*21/100 = 252
Total no. of girls enrolled for singing = 1200*12/100 = 144
Total no. of boys enrolled for dancing = 450 - 252 = 198
Total no. of boys enrolled for singing = 350 - 144 = 206
Required percentage =[(198+206)/(252+144)]*100 = 102.2%

UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 5

Read the information given below carefully and answer the following question.

Technological progress continues to accelerate and at some point, the technology of “mind uploading” becomes possible. Some human individuals upload and make many copies of themselves. Meanwhile, there is gradual progress in neuroscience and artificial intelligence, and eventually it becomes possible to isolate individual cognitive modules and connect them up to modules from other uploaded minds. Possibly, modules would need to be trained before they can communicate with each other effectively. Modules that conform to a common standard would be better able to communicate and cooperate with other modules and would therefore be economically more productive, creating a pressure for standardization. There might be multiple standards; some modules might specialize in translating between incompatible standards. Competitive uploads begin outsourcing increasing portions of their functionality: “Why do I need to know arithmetic when I can buy time on Arithmetic-Modules Inc. whenever I need to do my accounts? Why do I need to be good with language when I can hire a professional language module to articulate my thoughts? Why do I need to bother with making decisions about my personal life when there are certified executive-modules that can scan my goal structure and manage my assets so as best to fulfill my goals?” Some uploads might prefer to retain most of their functionality and handle tasks themselves that could be more efficiently done by others. They would be like hobbyists who enjoy growing their own vegetables or knitting their own cardigans; but they would be less efficient than some other uploads, and they would consequently be outcompeted over time.

Anjali is as much younger to Vijaya as Tanya is younger to Anjali. If the sum of the ages of Vijaya and Tanya is 48, how old is Anjali?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 10

Let the age of Anjali = x years.

Age of Vijaya = x + a years
Age of Tanya = x – a years
As given in the question, sum of ages of Vijaya and Tanya = 48
(x – a)  + (x + a) = 48
or  2x = 48
or x = 24 years.
Age of Anjali = x = 24 years
Hence, option (c) is the correct answer.

UPSC CSE Prelims Paper 2 Practice Test - 5 - Question 11

Biodiversity is the living fabric of our planet. It underpins human well-being in the present and in the future, and its rapid decline threatens nature and people alike. According to reports released in 2018 by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the main global drivers of biodiversity loss are climate change, invasive species, over-exploitation of natural resources, pollution and urbanization .Biodiversity loss implies the reduction and disappearance of species and genetic diversity and the degradation of ecosystems. It jeopardizes nature‘s vital contributions to humanity, endangering economies, livelihoods, food security, cultural diversity and quality of life, and constitutes a major threat to global peace and security. Biodiversity loss also disproportionally affects the most vulnerable exacerbating inequality .To halt or reverse this decline it is vital to transform people‘s roles, actions and relationships with biodiversity. This transformation has already begun with the commitment of the international community to the 17 Sustainable Development Goals (SDGs) of Agenda 2030. This global and holistic framework highlights the complex interconnections and interdependencies between society, biodiversity and sustainable development. It recognizes that human behaviour, values and choices shape people‘s interactions with biodiversity, all of which have a direct impact on our collective future on the planet. Awareness and appreciation of the diverse values of biodiversity need to be further amplified and mainstreamed within this global framework in order to transform human behaviour in favour of biodiversity conservation and its sustainable use. Many solutions exist for stopping and reversing the decline in biodiversity. UNESCO‘s diverse networks, programmes and partners have observed positive and inspiring seeds of change around the world. UNESCO also accompanies Member States and their people in their efforts to halt biodiversity loss by understanding, appreciating, safeguarding and using biodiversity sustainably. This publication highlights some of UNESCO‘s biodiversity-related actions and solutions, based on the Organization‘s unique mandate and its diverse normative instruments, networks, programmes and partners. These actions have reduced biodiversity loss and improved the lives of many people around the planet. For each thematic challenge, the publication highlights current actions and solutions that have been successfully implemented, as well as suggestions for improvement and innovation.
