• Magna Carta:-
• It​ was a charter of rights agreed to by King John of England in 1215.
• It established the principle that everyone, including the king, was subject to the law and had certain rights that could not be taken away without due process.
• Fundamental Rights:-
• The concept of fundamental rights is based on the idea that there are certain rights that are inherent to all human beings, regardless of their nationality, race, or gender.
• These rights are often enshrined in national constitutions and international treaties.
• While the Magna Carta was an important precursor to the concept of fundamental rights, it did not include all of the rights that we now consider to be fundamental.
• For example, it did not guarantee freedom of speech or religion..

Additional Information

• United States Constitution:-
• It includes a Bill of Rights that guarantees certain fundamental rights, such as freedom of speech, religion, and the press.
• However, the concept of fundamental rights predates the US Constitution, and the Magna Carta was the first document to establish the principle that everyone is subject to the law and has certain rights that cannot be taken away without due process.
• Canada:-
• It has a Charter of Rights and Freedoms that protects fundamental rights such as freedom of expression, religion, and peaceful assembly.
• However, the concept of fundamental rights predates the Canadian Charter, and the Magna Carta was the first document to establish the principle that everyone is subject to the law and has certain rights that cannot be taken away without due process.
• Australia:-
• It has a constitution that protects certain fundamental rights, such as freedom of religion and the right to vote.
• However, the concept of fundamental rights predates the Australian Constitution, and the Magna Carta was the first document to establish the principle that everyone is subject to the law and has certain rights that cannot be taken away without due process.

 Additional Information विशेष:

The erroneous part is option 1) i.e. 'are necessary.'

 

Key Points  

• The error lies in part 'are necessary.'
• According to the rules of subject-verb agreement, if two subjects are joined by 'as well as', 'with', 'along with', 'together with' etc, the verb will be according to the first subject.
• Here, the first subject 'Dedication' is an uncountable noun so it will take a singular verb 'is.'
• In the given sentence we need to use 'is' in place of 'are' to make the sentence grammatically correct.
• Hence, the correct answer is option 1.

 

Correct sentence: Dedication as well as hard work is necessary to achieve success in any field.

Shortcut Trick

Use the direct formula for two pipes: Time = (X × Y) ÷ (X + Y)

X = 10 hrs, Y = 15 hrs

Time = (10 × 15) ÷ (10 + 15) = 150 ÷ 25 = 6 hrs

∴ The correct answer is 6 hrs.

Alternate Method

Given:

Time taken by Pipe A = 10 hrs

Time taken by Pipe B = 15 hrs

Formula Used:

Total Work = LCM of individual times

Efficiency = Total Work ÷ Time

Calculations:

⇒ Combined Efficiency of A + B = 3 + 2 = 5 units/hr

⇒ Total Time taken together = Total Work ÷ Combined Efficiency

⇒ Time = 30 ÷ 5

⇒ Time = 6 hrs

∴ The correct answer is 6 hrs.

Additional Information

Pipes and Cisterns

If an inlet pipe fills in X hours and an outlet pipe empties in Y hours, the net work done in 1 hour is (1/X − 1/Y).

Efficiency Relation

Efficiency is inversely proportional to the time taken to complete a task. If the ratio of time is a:b, the ratio of efficiency is b:a.

A simple machine is a device that simply transforms the direction or magnitude of a force.

• The force overcome by the effort is called load or weight (W)
• The force applied to lift the load is called effort or power (P)
• A fixed point in the machine around which the machine rotates is called fulcrum (F)

The correct answer is ​1 and 2 Only.

Key Points

Mahajanapadas

• They were sixteen kingdoms or oligarchic republics that existed in ancient India from the sixth to fourth centuries BCE during the second urbanisation period.
• Most Mahajanapadas had a capital city, and many of these were fortified.
• The sixteen Mahajanapadas included: Kasi, Kosala, Anga, Magadha, Vajji, Malla, Chedi, Vatsa, Kuru, Panchala, Machcha, Surasena, Assaka, Avanti, Gandhara and Kamboja.

Vajji

• Its capital Vaishali (Bihar), was under a different form of government, known as Gana or Sangha.
• In a gana or a sangha there were not one, but many rulers.
• Sometimes, even when thousands of men ruled together, each one was known as a raja. These rajas performed rituals together.
• Women, dasas and kammakaras could not participate in assemblies.
• The territory of the Vajji mahajanapada was located on the north of the Ganga River and extended up to the Terai region of Nepal.
• On the west, the Gandak River was the boundary between it and the Malla mahajanapada, and possibly also separated it from the Kosala mahajanapada. Hence, pair 1 is correct.

Magadha

• It became the most important mahajanapada in about two hundred years.
• Many rivers such as the Ganga and Son flowed through Magadha.
• This was important for (a) transport, (b) water supplies (c) making the land fertile. Hence, pair 2 is correct.
• Besides, there were iron ore mines in the region that could be tapped to make strong tools and weapons.
• Magadha had two very powerful rulers, Bimbisara and Ajatasattu, who used all possible means to conquer other janapadas.
• Mahapadma Nanda was another important ruler.

Avanti

• It was an important kingdom of western India and was one of the four great monarchies in India when Buddhism arose, the other three being Kosala, Vatsa and Magadha.
• Avanti was divided into north and south by the river Vetravati. Hence, pair 3 is Incorrect.
• The country of Avanti roughly corresponded to modern Malwa, Nimar and adjoining parts of the Madhya Pradesh.
• Both Mahishmati and Ujjaini were located on the southern high road called Dakshinapatha extending from Rajagriha to Pratishthana (modern Paithan).
• Avanti was an important center of Buddhism and some of the leading theras and theris were born and resided there.
• Avanti later became part of the Magadhan empire when King Nandivardhana of Avanti was defeated by king Shishunaga of Magadha.

Kosala

• Kosala extended across both banks of the Sarayu (modern Ghaghara) River and north into what is now Nepal. Hence, pair 4 is Incorrect.
• According to the Hindu epic the Ramayana, Kosala was ruled by kings descended from the Sun; one of these kings was Rama, whose capital was Ayodhya (Oudh), near modern Faizabad.
• It rose in political importance early in the 6^th century BCE to become one of the 16 states dominant in northern India. It annexed the powerful kingdom of Kashi.

Given:

Fixed salary = Rs. 7200

Commission rate = 12%

Bonus rate = 1% (on sales above Rs. 15000)

Total monthly income = Rs. 14850

Formula Used:

Total Income = Fixed Salary + (Commission × Total Sales) + (Bonus × Sales Above Rs. 15000)

Calculation:

Let total sales = x.

Commission = 12% of total sales = 12/100 × x = 0.12x

If sales are greater than Rs.15000, sales above Rs.15000 = x - 15000

Bonus = 1% of (x - 15000) = 1/100 × (x - 15000) = 0.01(x - 15000)

Total Income = Fixed Salary + Commission + Bonus

⇒ 14850 = 7200 + 0.12x + 0.01(x - 15000)

⇒ 14850 = 7200 + 0.12x + 0.01x - 150

⇒ 14850 = 7050 + 0.13x

⇒ 14850 - 7050 = 0.13x

⇒ 7800 = 0.13x

⇒ x = 7800 / 0.13

⇒ x = 60000

The total sales of the company are Rs. 60000.

CONCEPT:

• White light: The light that contains all the wavelengths in the visible light range is called white light.

• It is the combination of seven light colors: 1. Violet, 2. Indigo 3. Blue, 4. Green, 5. Yellow, 6. Orange, 7. Red

• Dispersion of light: The splitting of a composite beam of light into its constituent colors is called dispersion of light.

• The dispersion of white light occurs because the colors of white light travel at different speeds through the glass prism.

• The dispersion was discovered by Sir Issac Newton.

• Newton discovered that light is made up of seven different colors.

EXPLANATION:

From the above discussion, we can say that,

• There are 7 different colours in white light. So option 3 is correct.
