1. IP address: 

An IP address has 4 parts numeric address. Each parts contains 8 bits. By using 8 bits we can represent a decimal number between 0 to 255(2 =256 numbers). Each part is separated by dot. A total of 4 × 8=32 bits used. But nowadays 128 bits are used for IP address. 

2. Media Access Control(MAC) address: 

It is a unique 12 digit hexadecimal number(IMEI for mobile phones, it is a 15 digit decimal number) assigned to each NIC by its manufacturer. This address is known as MAC address. It is of the form. MM:MM:MM:SS:SS:SS. 

3. Modem: 

It is a device used to connect the computer to the internet. It converts digital signal into analog signal (modulation) and vice versa (De modulation)

MAC means Media Access Control address. It is a unique 12 digit hexadecimal number(IMEI for mobile phones, it is a 15 digit decimal number) assigned to each NIC by its manufacturer. This address is known as MAC address and it is permanent. It is of the form. MM:MM:MM:SS:SS:SS. 

The first MM:MM:MM contains the ID number of the adapter company and the second SS:SS:SS represents the serial number assigned to the adapter by the company.

IP address means Internet Protocol address. It has 4 parts numeric address. Each parts contains 8 bits. By using 8 bits we can represent a decimal number between 0 to 255(28=256 numbers). Each part is separated by dot. A total of 4 × 8=32 bits used. But nowadays 128 bits are used for IP address.

Given:

Ratio of age of A and B = 5 : 4

Ratio of age of B and C = 4 : 3

Difference of age of A and C = 14 years

Calculations:

Let the present age of A and B and C be 5x, 4x and 3x respectively.

5x – 3x = 14

⇒ 2x = 14

⇒ x = 7

Present age of B = 4x

⇒ 4 × 7

⇒ 28 years

Present age of C = 3x

⇒ 3 × 7

⇒ 21 years

After 7 years, age of B = 28 + 7

⇒ 35 years

After 7 years, age of C = 21 + 7

⇒ 28 years

Ratio of age of C and B after 7 years =  28 : 35

⇒ 4 : 5

∴ The ratio of age of C and B after 7 years is 4 : 5

Given:

C.P of 1000 grams rock salt = Rs. 25

S.P of 1000 grams rock salt = Rs. 20

False weight = 800 grams

Calculations:

C.P of 1000 grams rock salt = Rs. 25

C.P of 800 grams of rock salt

⇒ 25/1000 × 800

⇒ Rs. 20

S.P of 1000 grams rock salt = Rs. 20

∴ there is no profit no loss as the shopkeeper bought the rock salt in Rs 20 Rs/kg and sold it for the same.

Sum of ratio terms = (5 + 3) = 8.

First part = Rs. (672 x (5/8)) = Rs. 420; 

Second part = Rs. (672 x (3/8)) = Rs. 252.

Given:

Glass 1 = 1 : 2, 90ml

Glass 2 = 3 : 4, 210 ml

Glass 3 = 2 : 5, 140ml

Calculation:

Glass 1 has capacity of 90 ml and has water to juice in ratio of 1 : 2

⇒ Amount of juice in glass 1 = (2/3) × 90

⇒ Amount of juice in glass 1 = 60

Glass 2 has capacity of 210ml and has water to juice in ratio of 3 : 4

⇒ Amount of juice in glass 2 = (4/7) × 210

⇒ Amount of juice in glass 2 = 120 ml

⇒ 10 ml removed hence, final quantity = 110 ml

Glass 3 has capacity of 140 ml and has water to juice in ratio of 2 : 5

⇒ Amount of juice in glass 3 = (5/7) × 140

⇒ Amount of juice in glass 3 = 100 ml

⇒ 10 ml added hence, final quantity is 110 ml

∴ both glasses 2 and 3 has maximum amount of juice that is 110 ml

Sum of ratio terms = (35 + 28 + 20) = 83. 

A's share = Rs. (1162 x (35/83))= Rs. 490; 

B's share = Rs. (1162 x(28/83))= Rs. 392; 

C's share = Rs. (1162 x (20/83))= Rs. 280.

Given:

Initial ratio of oil : kerosene = 2 : 7

Required ratio = 1 : 1

Calculation:

Let’s assume the container to be of 90 ml

⇒ Oil : kerosene = 2 : 7

⇒ Container has oil = (2/9) × 90

⇒ Container has oil = 20 ml

⇒ Container has kerosene = 70 ml

Now, Required ratio = 1 : 1

⇒ In order to attain this ratio both liquids needs to have equal parts

⇒ By adding 50 ml of oil, oil quantity increases = 20 +50

⇒ Oil quantity = 70 ml

⇒ Kerosene Quantity = 70 ml

∴ 50 ml of oil needs to be added to mixture

Let the number of 50 p, 25 P and 10 p coins be 5x, 9x and 4x respectively. 

(5x/2)+( 9x/ 4)+(4x/10)=206

50x + 45x + 8x = 4120

103x = 4120 

x=40. 

Number of 50 p coins = (5 x 40) = 200; 

Number of 25 p coins = (9 x 40) = 360; 

Number of 10 p coins = (4 x 40) = 160.

Given:

A bag contains 20 paise, 25 paise, and 50 paise coins in the ratio 8 ∶ 5 ∶ 4, and the amount is Rs. 436.5.

Calculations:

A bag contains 20 paise in ratio 8 = (1/5) × 8 = Rs 1.60 

Similarly, 25 paise in ratio 5 = (1/4) × 5 = Rs 1.25

And, 50 paise in ratio 4 = (1/2) × 4 = Rs 2.00

According to question,

⇒ 1.60 + 1.25 + 2.00 = 4.85  

⇒ 4.85  = 436.5 

Then, 1 = 90 

⇒ 90 × 2 = 180 

∴ The number of 50 paise coins = 180 × 2 = 360

A - Workers in the Primary Sector are underemployed.

Answer is : (b) Secondary

1. The value obtained is actually the GNP at market prices. Care must be taken to avoid double counting. 

2. The value of the final product is derived by the summation of all the values added in the productive process.

3. To avoid double counting, either the value of the final output should be taken into the estimate of GNP or the sum of values added should be taken. 

4. Double counting is to be avoided under value added method. 

5. Any commodity which is either raw material or intermediate good for the final production should not be included. 

6. For example, value of cotton enters value of yam as cost, and value of yam in cloth and that of cloth in garments.

7. At every stage value added only should be calculated.

Answer is : (c) Rs. 12,000

Answer is : (a) Primary

Answer is : (c) Tertiary

Answer is : (a) Primary

Correct option is: (a) Primary

Correct option is: (c) Tertiary

Correct option is: (a) Primary

The problem of double counting is the problem of estimating the value of goods and services more than once. 

For example:- A farmer produces 100 kg of wheat and sells it for Rs.4000 to Miller.

For Miller, wheat is an intermediate good. Miller converts wheat into flour. He sells it for Rs.5000 to a baker.

Baker manufactures bread from flour and sells the entire bread to final consumers for Rs.6000.

As a general practice , every producer treats its product as final output. Total value of output=4000+5000+6000=15000.But the value of wheat and flour are counted more than once.

The problem of double counting can be avoided by (i) Final output method and (ii) Value added Method.

Correct option is: (c) Tertiary

Nature of Management:

• Universal Process: Wherever there exists human pursuit, there exists management. Without effective management, the intentions of the organisation cannot be accomplished.
• The factor of Production: Equipped and experienced managers are necessary for the utilisation of funds and labour.
• Goal-Oriented: The most significant aim of all management pursuit is to achieve the purposes of a firm. The aims must be practical and reachable.
• Supreme in Thought and Action: Managers set achievable goals and then direct execution on all aspects to achieve them. For this, they need complete assistance from middle and lower degrees of management.
• The system of authority: Well-defined principles of regulation, the regulation of proper power and efficiency at all degrees of decision-making. This is important so that each self must perform what is required from him or her and to whom he must report.
• Profession: Managers require to control managerial expertise and education, and have to adhere to a verified law of demeanour and stay informed of their human and social responsibilities.
• Process: The management method incorporates a range of activities or services directed towards an object.

Significance of Management:

• Achieving Group Goals: Management encourages collaboration and coordination amongst workers. A general control must be provided to the organisational and personal objectives in order to favourably accomplish the aims.
• Increases Efficiency: Management improves productivity by managing resources in a reliable conceivable way in order to decrease cost upscale potency.
• Creates Dynamic organisation: Management undertakes the conditions by assuring that these variations are well accepted privately and that objection to change is controlled.
• Achieving personal objectives: Management promotes leadership and furnishes motivation to the employees to operate effectively in order to accomplish their personal aims while working towards the organisational goals.
• Development of Society: Management helps in the enhancement of community by manufacturing reliable quality commodities, establishing employment chances and fostering innovative technologies.

The correct option is (D) Basic needs

• The ILO report for the 1976 World Employment Conference defined basic needs in terms of food, clothing, housing, education, and public transportation.
• The ILO was founded in October 1919. It is headquartered in Geneva, Switzerland.
• The current Director-General of ILO as of March 2021 is Guy Ryder.
• Employment was both a means and an end, and participation in decision-making was also included.
• This approach reversed conventional practice, which was to project a desirable annual rate of per capita economic growth into the future.
• The latter was a forward rolling approach while the basic needs approach achieved more precision by setting specific production targets and deriving the desirable rate of economic growth implied.
• The basic needs development strategy was also more practical than conventional strategies.

Short run supply curve: In a perfectly competitive market, the short run supply curve is that part of its Marginal cost curve where the Marginal Cost curve is rising from the Average Variable Cost curve. Thus, it is evident from the diagram that when price rises the quantity supplied also rises and vice versa.

Deflection sensitivity of a cathode ray tube is defined as the deflection of the screen per unit deflection voltage.

\(s = \frac{D}{{{E_d}}} = \frac{{L{t_d}}}{{2d\;{E_a}}}m/v\)

Where,

L = distance between screen and centre of the deflecting plates

D = Distance between deflecting plates

L_d = Length of deflecting plates

E_a = Accelerating voltage

E_d = Potential between deflecting plates

Concept:

Static sensitivity:

It is defined as the ratio of the magnitude of response to the magnitude of the quantity being measured. In simple terms, it can also be said as the ratio of output to input.

\(\rm Static\;sensitivity=\frac{\Delta\;Output}{\Delta\;Input}\)

Calculation:

Given:

Output = 12mm, input = 3 A 

As the input of 3A produces a deflection of 12 mm.

\(\rm Static\;sensitivity=\frac{\Delta\;Output}{\Delta\;Input}\)

\(\rm Static\;sensitivity=\frac{12}{3}=4\;mm/A\)

\(=(x+1)(-x^2+7x-10)\)

\(=(x+1)(-x^2+2x+5x-10)\)

\(=(x+1)(-x(x-2)+5(x-2))\)

\(=(x+1)(x-2)(-x+5)\)

\(=-(x+1)(x-2)(x-5)\)

β(m, 1/2) = \(\frac{Γ(m)Γ(1/2)}{Γ(m+1/2)}\) \(\left(\because\beta=\frac{\Gamma(m)(n)}{\Gamma(m+n)}\right)\)

\(=\cfrac{\Gamma(m)\Gamma(m)\Gamma(\frac12)}{\Gamma(m)\Gamma(m+\frac12)}\) (Multiplying numerator & denominator by \(\Gamma(m)\))

\(=\cfrac{\Gamma(m)\Gamma(m)\Gamma(\frac12)}{\frac{\sqrt{\pi}}{2^{2m-1}}\Gamma(2m)}\) (\(\because\) \(\Gamma(m)\Gamma(m+\frac12)=\frac{\pi}{2^{2m-1}}\Gamma(2m)\))

\(=2^{2m-1}\frac{\Gamma(m)\Gamma(m)}{\Gamma(2m)}\frac{\sqrt\pi}{\sqrt\pi}\) (\(\because\Gamma(\frac12)=\sqrt\pi\))
