Given:

Mohit got 30% marks and failed by 25 marks

Another student scored 38% and

He got 15 more marks than passing marks

Calculation:

According to the question

⇒ 30% + 25 = 38% – 15

⇒ (38% – 30%) = (15 + 25)

⇒ 8% = 40

⇒ 1% = 5 marks

Now,

5% = 25 marks 

Then,

The necessary pass percentage required = (30% + 5%)

⇒ 35%

∴ Required pass percentage is 35%

The triangle 6 shown in figure and another is ADB,ACB, BDC,ADC, so that total number of triangle is 10

The logic is:

Column 1: 9 × 5 × 3 = 135

Column 2: 5 × 7 × 4 = 140 

Similarly,

Let the missing number in column 3 be 'a'.

So, 5 × a × 5 = 150

⇒ 25 × a = 150

⇒ a = 150 ÷ 25

⇒ a = 6

Hence, ‘6’ is the correct answer.

The pattern followed is:

Hence, the correct answer is "PM".

There are 8 triangles in the figure. By counting the individual triangles, we can see that there are 2 large triangles, 4 medium triangles, and 2 small triangles, making a total of 8 triangles.

‘Knife’ is related to ‘Cut’, means we use knife for cutting.

Similarly,

We use pen for writing.

Hence, Write is the correct answer.

Information and communication technology (ICT) refers to the use of electronic technology to send save, create, display, share or exchange information. Radio, television, video, DVD, satellite systems, computers, etc. are included in the ICT technologies.

• The tools of ICT are not a single technology but a combination of hardware, software, multimedia, and delivery systems. It may be in the form of audio, visual, and audio-visual. 

Key Point

Advantages of ICT Tools:

• Cost efficient - ICT tools are cost efficient as sending an email is cheaper than phone calls. ICT has also helped to automate business practices, thus restructuring businesses to make them exceptionally cost-effective. ICT tools make availability of free e-contents.
• ICT as Auido-Visual aid - A teacher can use ICT tools as teaching aids to stimulate the interest of students in learning. For example, a teacher who is going to introduce adjectives to class Ist students. He can use graphics, visual presentation, and audio-visual aids to make classroom learning interesting.
• Direct classroom learning: ICT tools are used in direct classroom learning as these tools shift the learning from solitary learning to learning with others. It makes learning more active in nature as there is direct interaction of the learner with ICT tools. It places the learner at the center and encourages collaborative learning in the classroom.

Hint

• Reliance on technology: Errors can be caused by over-reliance on and trust in technology’s proper function. Technology can occasionally malfunction, misdirect users, or give incorrect information or recommendations that result in users changing a previously correct decision or following a pathway that leads to error. Over-reliance on technology can result in serious consequences.

Hence, it is clear that reliance on technology is not an advantage of ICT tools.

IT and ICTs are very often interchangeably used in the context of modern technology infrastructure. ICT is a broad and comprehensive term, which comprises information technology and communication technology. Information technology includes radio, television, computer and internet, teleconferencing and mobile technology.

Key Points

• All these information technologies have mainly two types of communication technologies.
  • Satellite based communication and
  • Terrestrial based communication.
• Satellite based communication is the communication, which takes place between sender and receiver through a communication satellite whereas terrestrial based communication is the communication, which takes place through a network of transmitters spread across a geographical area, a country, or a state.
• This type of communication is used in the transmission of radio and television in India.
• However, with the launch of a series of satellites by Indian Space Research Organization (ISRO), satellite based communication is being used for telecommunication.

Important Points

• Communicating information effectively by making use of appropriate technology is called information and communication technology (ICT).
• In all, ICT is an umbrella term that includes many communication devices such as radio, television, cellular phones, computers and network, satellite systems and so on.
• ICTs are defined, as a “diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information.

Gravitational force between two objects is mathematically represented as:
F = G * (m1*m2) / r²
Applying the Law of Gravitation to the Given Problem
Given that the initial force F is due to two objects each of mass m separated by a distance r.
Substituting these into the formula gives:
F = G * (m*m) / r²
The problem then states that the mass of each of the objects is doubled (to 2m) and the distance between them is also doubled (to 2r).
The new force F' using these values in the formula would be: F' = G * (2m*2m) / (2r)²

Simplifying this gives:
F' = 4G * (m*m) / 4*r²
This simplifies further to:
F' = G * (m*m) / r²
Comparing this with the original equation for F, we find that:
F' = F

Thus, the force remains the same (F) even when the mass of each of the objects is doubled and the distance between them is also doubled. Hence, the correct answer is A: F.

The impending motion refers to the state of a body when it is on the verge of slipping. In such cases, the static friction has reached its upper limit and is given by the equation, F=μ_sN

Q-factor: In LCR Circuit, the ratio of resonance frequency to the difference of its neighbouring frequencies so that their corresponding current is 1/√2​ times of the peak value, is called Q-factor of the circuit.
Formula: Q=(1/R)​ √(L/C)​​
So, Q ∝1/R
Conditions for the large value of Q factor:
(i) Value of CL​ should be large.
(ii) Value of R should be less.
 

The child should hold the umbrella in the direction at which the rain appears to fall on him, which is the direction of relative speed of rain with respect to the  child.

To answer this question you should know the definitions of tensile, compressive and shear stress.
Tensile stress causes change (increases the length of cylinder) in the length of the object, compressive strength changes the volume of the object (it can be applied from all sides of the object), shear stress is applied parallel to the surface of an object (in case of the cylinder shear stress will be parallel to circular surface) we can apply all the three stresses in case of cylinder hence option D is correct.

The magnetic moment of a current carrying loop is given by

the direction is towards positive z-axis.

The response of a young child on the basis of the past situation is related to the 'Law of Analogy' of learning. 
The 'Law of Analogy' principle was developed by Edward Thorndike. According to him, an individual makes use of old experiences while learning a new situation. The way young child did he identified the similarities between the past situation and the present one.
Hence, the correct answer is, 'Law of Analogy' of learning.

The correct answer is National Higher Education Regulatory Council (NHERC).
Important PointsThe National Education Policy (NEP) 2020 proposed the creation of a Higher Education Commission of India (HECI) as a single overarching umbrella body for higher education.

• This new regulatory body would replace the existing separate regulatory institutions in the higher education sector to improve coordination and maintain standards.
• The HECI is set to have four independent verticals, namely:

1. National Higher Education Regulatory Council (NHERC)
2. General Education Council (GEC)
3. Higher Education Grants Council (HEGC)
4. National Accreditation Council (NAC)

Each of these verticals has specific roles and responsibilities, from regulation, to setting standards, to funding, to accreditation.

• According to NEP 2020, the first vertical of the HECI will be the National Higher Education Regulatory Council (NHERC).
• This council will be the primary regulator for higher education in India, including teacher education, excluding medical and legal education.
• This implies that all other bodies, like UGC and AICTE, would cease to be regulatory bodies and would only be responsible for standards setting and providing grants.

Therefore, the correct answer would be the "National Higher Education Regulatory Council (NHERC)".

National Education Policy 2020 is India’s First 21st Century Education Policy. Which makes many relevant changes in the education system from elementary education to Higher education.

Key PointsAccording to NEP 2020:

• ​A "5+3+3+4" curriculum framework is planned as part of the 2020 education reform.
• Based on age divisions, NEP 2020 has divided schooling into several phases.
• The policy prioritizes three years of preschool and twelve years of formal education.

Thus, classes 3rd to 5th are​ included in the preparatory stage as per the new education policy 2020

The sentence indicates the contraction of skeletal muscles. Rhythmic contraction would mean a strong, regular pattern of movement or sound, while nonmetrical, arrhythmic, and unrhythmic mean the opposite.
In the above sentence, Rhythmic contraction suits the meaning of the sentence. Thus, option 4 is the correct answer.

The correct word is 'who' which is a pronoun used to introduce a clause giving further information about a person or people previously mentioned.

In the sentence, we are being told that Sir Surendranath is the greatest Indian orator. The given sentence expresses this in comparative degree. Therefore, the correct answer is 'greater'. 

'Spellbinding' is 'something that takes a person by complete surprise as if he/she has been under the influence of magic'.
The meanings of the other words are:
Amusing: causing laughter and providing entertainment.
Tantalising: tease someone with the sight or promise of something that is unobtainable.
Tormenting: inflicting severe physical or mental suffering.
No other option has the same meaning as spellbinding. Thus option 4 is the correct answer.
Example-The beauty of the Himalayan ranges spellbound all people.
