This is very simple :

f(x) = 2x+2 

f(3) = 2*3+2=8

f(f(3))= 2*f(3)+2

       = 2*8+2

       = 18

Hence (A) is the answer

Nihon Hidankyo was founded in 1956. The organization was established to unite survivors of the atomic bombings and advocate for nuclear disarmament, raising awareness about the rights and experiences of Hibakusha.

The International Campaign to Abolish Nuclear Weapons (ICAN) was awarded the Nobel Peace Prize for its significant contributions to the global disarmament movement. This recognition underscores the importance of collective efforts to eliminate nuclear weapons.

The use of atomic bombs during World War II ignited a worldwide debate regarding the ethics of deploying such devastating weapons. This discussion continues to be relevant as nations grapple with the moral implications of nuclear armament and warfare.

Hibakusha actively share their personal stories to emphasize the catastrophic consequences of nuclear warfare. Their testimonies serve as powerful tools in advocating for nuclear disarmament and educating the public about the long-term effects of radiation exposure.

Nihon Hidankyo's mission is to advocate for nuclear disarmament. The organization works not only to protect the rights of Hibakusha but also to educate the public about the dangers associated with nuclear weapons and to promote global peace initiatives.

The atomic bombings significantly influenced international relations and contributed to the establishment of the United Nations. The horrific consequences of nuclear warfare underscored the need for international cooperation to prevent future conflicts and promote peace, leading to the creation of various treaties aimed at nuclear non-proliferation and disarmament.

The main focus of the 2024 Army Commanders' Conference is to create a national security strategy. This involves comprehensive discussions on various security aspects, including civil-military cooperation and the DIME strategy (Diplomatic, Information, Military, and Economic efforts) to address modern threats. This emphasis on a structured approach to security is crucial given the evolving nature of international relations and security challenges.

The meristematic cell layer which is responsible for the development of the periderm is called phellogen. It produces cells both in and outwards. Cells which grow inwards will be phelloderm, and cells which develop outwards will be phellem or cork

• In these two positions one of the common face having 1 point is in the same position.
• Therefore according to rule (2): 
  There will be 4 points on the required face.

Let the number of apples be 100.

On the first day, he sells 60% apples ie.,60 apples. Remaining apples =40.

He throws 15% of the remaining i.e., 15% of 40 = 6.Now he has 40 - 6 = 34 apples

The next day he throws 50% of the remaining 34 apples i.e., 17.

Therefore, in all, he throws 6 + 17 =23 apples.

The correct answer is A. 

1^st Method:
8th term = a+7d = 39 ......(i)
12th term = a+11d = 59 ......(ii)
Subtracting (ii) from (i) we get,
a + 7d - a - 11d = 39 - 59 
⇒ 4d = 20 or d = 5
Hence, a + 7*5 = 39
Thus, a = 39 - 35 = 4.

2^nd Method (Thought Process):
8th term = 39
And, 12th term = 59
Here, we see that 20 is added to 8th term 39 to get 12th term 59 i.e. 4 times the common difference is added to 39.
So, CD = 20/4 = 5.
Hence, 7 times CD is added to 1st term to get 39. That means 4 is the 1st term of the AP.

As a gemstone used in jewellery, silicon carbide is called "synthetic moissanite" or just "moissanite". Moissanite is similar to diamond in several important respects it is transparent and hard . Moissanite has become popular as a diamond substitute, and may be misidentified as diamond, since its thermal conductivity is close to that of diamond, more than any other diamond substitute. The properties of carbon fibres, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion, make them very popular in aerospace, civil engineering, military, and motor sports. Dichlorodifluoromethane (R-12) is a colourless gas, and usually sold under the brand nameFreon-12, is a chlorofluorocarbon halo-methane (CFC), used as a refrigerant and aerosol spray propellant. In photosynthesis, solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar). Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water.

Take the total surface area of the initial cone into consideration and then proceed.

It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. 

• Mangalagiri Sarees and Fabrics are produced by performing handicraft weavingin Mangalagiri, a town in Guntur district of the Indian state of Andhra Pradesh.
• It was registered as one of the handicrafts in the geographical indication from Andhra Pradesh by Geographical Indications of Goods (Registration and Protection) Act, 1999. 
• The Mangalagiri fabric is produced by weaving with the help of pitlooms from combed yarn by warp and woof interlacing.
• The fabric then undergoes the process of dyeing.
• The Nizam design is another characteristic of the fabric.

We shall first calculate the number of odd days till 31 December 1946:

• Number of odd days in the first 1600 years = 0 odd day
• Number of odd days in the next 300 years = 1 odd day
• Now, 46 years had 11 leap years and 35 ordinary years.
• The number of odd days in 46 years = (2 × 11) + (1 × 35) = 22 + 35 = 57 = 8 weeks and 1 odd day.

Now, we shall calculate the number of odd days in 1947 till 15 August:
Month (Days):

• January(31)
• February(28)
• March(31)
• April(30)
• May(31)
• June(30)
• July(31)
• August(15)

Days = 31 + 28 + 31 + 30 + 31 + 30 + 31 + 15 = 227 i.e. 32 weeks and 3 odd days
So, the total number of odd days till 15 August 1947 = 0 + 1 + 1 + 3 = 5
On counting five days from Monday, we get Friday.
Therefore, 15 August 1947 was a Friday.

The word sovereignty appears in the beginning of the Preamble to the Constitution of India, as the first attribute of the independent republic of India. Its placement as the first among the core principles of the republic underlines its importance in the Constitution.

Sovereignty is mentioned in the Constitution under Fundamental Duties, which are to be followed by all Indian citizens but cannot be legally enforced. Article 51A(c) states that it is the duty of all citizens “to uphold and protect the sovereignty, unity and integrity of India.”

It is also mentioned in the oaths for positions like the Chief Justices, Union Ministers and Members of Parliament under the Third schedule: “…I will bear true faith and allegiance to the Constitution of India as by law established, that I will uphold the sovereignty and integrity of India…”

The given numbers are consecutive prime numbers in increasing order starting with 17.
Hence, the next number in the series is 41.

Plasmodium completes their life cycle in two hosts, female anopheles and human beings. The motile zygote of plasmodium occurs in gut of female anopheles, which get transferred to human being during mosquito bite.

• The excessive extraction of groundwater for drinking and irrigation has shifted the Earth’s axis of rotation, according to a new study. Noting that humans pumped out around 2,150 gigatons of groundwater between 1993 and 2010, the study says that the planet’s axis has drifted at the rate of 4.36 cm per year towards the east.
• Although the shift isn’t significant enough to have real-life consequences, the study shows that humans have extracted so much water from the ground that it has impacted the planet’s axis and contributed to global sea level rise.
• Earth spins around an imaginary axis which passes through the north pole, its centre of mass and the south pole — just like a top spins around its spindle. Scientists for years have known that the poles and the axis keep shifting naturally as the mass distribution in and on the planet changes. This phenomenon is known as “polar motion”.
• For instance, rocks slowly circulating inside Earth’s mantle causes the planet’s mass to shift, leading to a change in the position of the rotational axis. 
• There are several other reasons responsible for polar motion like ocean currents and even hurricanes. But this phenomenon is also impacted by human activities.

A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.

ONDC is an interoperable network based on the BeckN protocol that anyone can piggyback on. It seeks to break down silos in digital commerce by enabling platforms of varying configurations (big or small) to connect and operate seamlessly on it.

It comprises different entities called ‘Network Participants’, including Buyer Applications, Seller Applications, and Gateways that perform the search and discovery function. Imagine a scenario where all the large e-commerce platforms, from food delivery to clothing and fashion to conveyance, are accessible in one place, along with your neighbourhood start-ups, shops, and kirana stores.

How does this help, and why is it significant?
By moving the exchange of goods and services from a platform-centric approach to a network-centric approach, ONDC eliminates the need for buyers and sellers to use the same application, and promotes the discoverability of local digital stores across industries.

What is ONDC’s inclusive governance approach?
The ONDC entity, a not-for-profit company incorporated under Section 8 of the Companies Act 2013, manages and operates the ONDC Network.

It is responsible for building and maintaining the underlying infrastructure (common registries and protocols) as well as defining the rules of engagement and code of conduct for the Network Participants through the ONDC Network Policy and the ONDC Network Participant Agreement.

To what extent will the government be involved in ONDC?
ONDC has been endorsed by the Department for Promotion of Industry and Internal Trade (DPIIT) under the Union Ministry of Commerce and Industry. DPIIT is not involved in ONDC’s funding, but is at the forefront of its evangelisation through light-touch governmental oversight.

To ensure a market+community driven approach to decision-making, the board includes representatives from banks, the government, and independent industry and civil society members.

PMSSY was announced in 2003 with objectives of correcting regional imbalances in the availability of affordable/ reliable tertiary healthcare services and also to augment facilities for quality medical education in the country.

A High Ambition Coalition, which now has more than 100 countries including India, the US, and the UK, came about and put the focus on ‘30×30’ goals – protecting 30 per cent of the ocean by 2030.
Statement 1 is incorrect.

Time from Monday noon (12 o' clock) to following Monday 2 pm = 7 day 2 hours
= 7×24+2
= 168+2
= 170 hours 
Total time gained Monday noon (12 o' clock) to following Monday 2 pm = 2 min + 4 min 48 sec
= 6 min 48 sec = 6(48/60) mins = 6(4/5) mins = 34/5 mins
The given watch gains 34/5 mins in 170 hours
Given that the said watch was 2 minutes low at Monday noon. Hence when it gained 2 minutes, the time was correct.
The given watch gains 34/5 mins in 170 hours
⇒ The given watch gains 2 mins in  170 x 5/34 x 2 hours
= 5 * 5 * 2 hours = 50 hours
Hence the time was correct after 50 hours from Monday noon = after 2 days 2 hours from Monday noon = 2 pm on Wednesday
