Question Discussion & Solution

The correct answer is Article 167.

• Article 167 of the Indian Constitution defines the duties of the Chief Minister.
• It has specified in the second schedule.
• A chief minister is understood to be "first among equals".

A Chief Minister must be:

• Chief Minister must be a citizen of India.
• Chief Minister should be a member of the state legislature.
• If a person is elected chief minister who is not a member of the legislature, then he/she must take permission from the governor.
• Chief Minister must be 25 years of age or more.

The Venn diagram that best represents the relationship between Uttar Pradesh, Jhansi, Goa is shown below:

Jhansi is a city of Uttar Pradesh.

Whereas, 

Uttar-Pradesh and Goa both are different States of India thus will come as a separate circle.

Hence, Option (4) is correct.

Additional InformationUttar-Pradesh:

• The Dudhwa National Park is located in Terai and is spread over an area of 490 sq.km. The national park also has the Dudhwa tiger reserve within its premises.
• National Chambal Sanctuary is also known as the National Gharial Wildlife Sanctuary that is home to the endangered gharial or small crocodile. The river Chambal follows through this sanctuary as the hills and ravines build many sandy beaches inside the park.
• Situated in the district of Pilibhit in Northern Uttar Pradesh, Pilibhit Tiger Reserve is one of the 41 Project Tiger reserves of the country. The forest cover here is dense which is why the tigers have a good eco-system to survive in with enough prey. The reserve is home to over 127 different kinds of animals and 556 kinds of birds.
• The Nawabganj bird sanctuary also popularly known as Shahid Chandra Shekhar Azad bird sanctuary is situated in the Unnao district of Uttar Pradesh. The sanctuary is famous for being the temporary home of more than 250 kinds of birds. The birds come all the way from former USSR countries.
• Chandraprabha Wildlife Sanctuary is located near the city of Varanasi, Uttar Pradesh. The sanctuary is not as famous as the other ones in the area but the place is rich in scenic landscapes and waterfalls. The two famous waterfalls are; Rajdari and Devadari. The variety of animals found here are the wild boar, Indian gazelle and blackbucks.

Goa:

• Spread over an area of 211 square kilometres, Netravali Wildlife Sanctuary is one of the newly established wildlife sanctuaries in Goa.
• With the number of Royal Bengal tigers that can be found at the Mhadei Wildlife Sanctuary, authorities are considering to promote the place as one of the Project Tiger Reserves. Among the very popular sanctuaries of Goa, it is located near Valpoi town in Sattari Taluka.
• The Bhagwan Mahaveer Sanctuary is the biggest wildlife sanctuary in Goa and is located in Sanguem taluka. It spreads over an area of 240 square kilometres. Along with the stunning landscapes of the Western Ghats, the sanctuary also encompasses the very famous Dudhsagar Falls and a number of temples from the era of the Kadamba Dynasty. You can also visit the famous Devil’s Canyon View Point, a perfect place to spot wildlife and birds.
• Set up in 1968 and spread over an area of 105 square kilometres, the Cotigao Wildlife Sanctuary is situated in the southern part of Goa, near Canacona Taluka.
• The core area of Bhagwan Mahaveer Sanctuary is known as the Molem Wildlife Sanctuary. It is located in the Sanguem region and is claimed to house up to 120 different species of birds such as drongo, golden oriole, the great Indian hornbill, three-toed kingfisher, wagtails, and fairy bluebird.

Concept:

• The laws dealing with ideal gases naturally called ideal gas laws, and the laws determined in the seventeenth century by Boyle's observational work and in the eighteenth century by Charles.
• The Boyles Law states that the gas pressure is inversely proportional to the gas volume for a given mass of gas stored at a constant temperature.
• Charles Law states that the gas volume is directly proportional to the gas temperature for a given fixed mass of gas stored at a constant pressure. 
• An ideal gas is a gas that follows the equation:

PV = nRT at all temperatures and pressure, where P = Pressure of the ideal gas. V = Volume of the ideal gas n = Amount of ideal gas measured in terms of moles 

R = Universal gas constant T = Temperature

Mole Concept -

•  The quantity one mole of a substance signifies 6.022 × 1023 number of particles of that substance which may be atoms, molecules, or ions.
• The quantity is a universal constant like Dozen, Gross, etc., and is known as Avogadro number, denoted by NA. after the scientist Amedeo Avogadro.
• Examples- In one mole of H2, there are 6.022 × 1023 molecules of hydrogen, and the number of atoms is 2 × 6.022 × 1023, as one molecule of hydrogen contains two-atom each.
• The mass of one mole of a substance is called its Molar Mass (M) or Atomic mass expressed in grams.
• The volume occupied by a mole of gas is 22.4 L at NTP, called its Molar Volume.
• The no. of moles (n) is calculated as =

The number of particles / Avogadro’s number.

To summarise, we can say, 

Calculation:

• The molar mass of 1 mole of H₂SO₄ is =

2 × 1 + 32 + 4 × 16 = 98g

• The molar mass of 1 mole of Silver, Ag is its molecular mass 108g.
• The molar mass of CO₂ is = 12 + 2× 16 = 44g.
• 44g of CO₂ means one mole.
• 1 mole of Oxygen weighs 16 + 16 = 32g.
• Hence, the highest mass is of 1 mole of Ag.

• For most computer languages, the name of the file that holds the source code to a program is immaterial
• However, in Java the name given to a source file is very important
• The Java compiler requires that a source file uses the .java filename extension
• Only file.java follow the properties in the given options
• In Java, a source file is officially called a compilation unit; It is a text file that contains one or more class definitions

Hence, “8” will come in the place of question mark.
