The question asks to identify a watershed development and management program implemented jointly by the central and state governments in India. This requires knowledge of prominent government initiatives in the field of water resource management and rural development.
Correct Option: A) Hariyali is a watershed development and management program that was implemented by the central and state governments. It was launched in 2003 with the objective of empowering local communities, particularly Gram Panchayats, to undertake watershed development activities, including water harvesting, afforestation, and soil conservation, to improve the livelihoods of rural populations.
The question asks about the number of output ports in peripheral I/O. This refers to the addressing capability for I/O devices in a typical computer architecture, specifically when using a dedicated I/O address space.
A) 256. With an 8-bit I/O address bus, a system can address \(2^8 = 256\) unique I/O ports. This is a standard addressing capability for peripheral I/O in many architectures.
The question asks about the original host country for the AFC Asian Cup Football tournament in 2023, before any withdrawals or changes. This requires knowledge of the initial selection process for the tournament.
Correct Option: B) China was originally selected to host the AFC Asian Cup Football tournament in 2023. They later withdrew, and Qatar became the host.
The question asks to identify the most populated state in India according to the 2011 Census. This requires recalling demographic data from the Census of India, 2011.
According to the Census of India 2011:
Comparing these figures, Uttar Pradesh clearly stands out as the most populated state.
C) Uttar Pradesh is the most populated state of India according to the 2011 Census, with a population of nearly 200 million.
The question asks to identify the city that is NOT part of the Golden Quadrilateral highway network. To answer this, one needs to know the major cities connected by this network.

Hyderabad is a major city in India, but it is not one of the four metropolitan cities directly connected by the main Golden Quadrilateral network. It is connected by other national highways that branch off from the GQ, but it does not lie on the main quadrilateral itself.
The problem provides a ratio between two variables, \(x\) and \(y\), and asks to find the ratio of two algebraic expressions involving \(x\) and \(y\). We can express one variable in terms of the other using the given ratio and then substitute this into the expression to simplify it.
Understand the given ratio:
We are given that \(x : y = 3 : 4\). This can be written as a fraction:
Express one variable in terms of the other:
From the above equation, we can express \(x\) in terms of \(y\):
Substitute into the expression:
We need to find the ratio \((4x + 3y) : (4y - 4x)\). Let's substitute \(x = \frac{3}{4}y\) into both parts of the ratio:
Numerator part:
\[ 4x + 3y = 4\left(\frac{3}{4}y\right) + 3y \]\[ = 3y + 3y \]\[ = 6y \]Denominator part:
\[ 4y - 4x = 4y - 4\left(\frac{3}{4}y\right) \]\[ = 4y - 3y \]\[ = y \]Form the new ratio:
Now, substitute these simplified expressions back into the ratio:
Simplify the ratio:
Since \(y\) is a common factor (and assuming \(y \neq 0\), which must be true for the initial ratio to be defined), we can cancel \(y\) from both sides:
B) The calculated ratio is \(6 : 1\), which matches option B.
The question asks about the number of demands Mahatma Gandhi made in his letter to Lord Irwin, which eventually led to the Gandhi-Irwin Pact. This is a factual question related to Indian history, specifically the Civil Disobedience Movement.
B) 11 — Mahatma Gandhi presented 11 demands to Lord Irwin in his letter of January 31, 1930. These demands were a precursor to the Civil Disobedience Movement and formed the basis for later negotiations leading to the Gandhi-Irwin Pact.
This question asks us to identify implicit assumptions based on a given statement. An implicit assumption is something that is not explicitly stated but must be true for the statement to make sense or be logical. We need to analyze the statement and each assumption to see if it necessarily follows from the statement.
A) Both A and B are implicit
As analyzed above, the decision to go home-to-home for bill collection implies both a belief in the effectiveness of this method (Assumption A) and an increased focus on bill collection (Assumption B).
What was India's rank in terms of size of economy according to the GDP ranking of 2019?
The question asks for India's rank in terms of economic size (GDP) in 2019. This requires recalling or knowing the economic rankings for that specific year.
D) 5th — According to various international reports and economic data for 2019, India's Gross Domestic Product (GDP) ranked it as the 5th largest economy in the world, surpassing countries like the United Kingdom and France.
The question asks about the number of times India has been elected as a non-permanent member of the UN Security Council (UNSC) up to October 2020. This requires factual knowledge about India's history with the UNSC.
