Concept:

• \({\log _{{\alpha ^\beta }}}m = \frac{1}{\beta }{\log _\alpha }m\)
• \({\log _\alpha }\frac{m}{n} = {\log _\alpha }m - {\log _\alpha }n\)
• \(If \ {\log _\alpha }m = {\log _\alpha }n\;\ then\;m = n\)

Calculation:

\(\log_3 (x + 2)(x + 4) + \log_{\frac 1 3} (x + 2) < \frac 1 2 \log_\sqrt 3 7\)

As we know that, \({\log _{{\alpha ^\beta }}}m = \frac{1}{\beta }{\log _\alpha }m\)

\({\log _3}\left( {x + 2} \right)\left( {x + 4} \right) - {\log _3}\left( {x + 2} \right) < {\log _3}7\)

As we know that, \({\log _\alpha }\frac{m}{n} = {\log _\alpha }m - {\log _\alpha }n\)

\({\log _3}\left( {x + 4} \right) < {\log _3}7\)

As we know that, \(if \ {\log _\alpha }m = {\log _\alpha }n\;\ then\;m = n\)

⇒x + 4 < 7

⇒ x < 3 ------------(1)

For \({\log _3}\left( {x + 2} \right)\left( {x + 4} \right)\) to exist \(x ∈ ( - 2, \infty )\)---------(2)

For \({\log _3}\left( {x + 2} \right) ⇒ x ∈ ( - 2, \infty )\)-----------------(3)

By combining equation 1, 2, 3 we get \(x ∈ ( - 2,3)\)

Hence, option B is the correct answer.

An error is something you have done which is considered to be incorrect or wrong, or which should not have been done. There are three types of error: syntax errors, logical errors and run-time errors. (Logical errors are also called semantic errors).

1. Intrinsic value of an option at a given time is the amount the holder of the option will get if he exercises the option at that time. 

2. The intrinsic value of a call is Max [0, (St — K)] which means that the intrinsic value of a call is the greater of 0.

1. Order cancellation: functionality can be performed only for orders which have not been fully or partially traded (for the untraded part of partially traded orders only) and only during market hours and in pre-open period.

2. Single Order Cancellation: Single order cancellation can be done during trading hours either by selecting the order from the outstanding order screen or from the function key provided.

3. Quick Order Cancellation: (Cancel All) is an extension of Single Order Cancellation enabling a user to cancel multiple outstanding orders in various trading books subject to the corporate hierarchy.

1. An out-of-the-money (OTM) option would lead to a negative cash flow if it were exercised immediately. 

2. A call option on the index is out-of-the-money when the current index stands at a level which is less than the strike price (i.e. spot price < strike price).

A={7,8} and B={5,4,2}
We know that the Cartesian product of P×Q of two non-empty sets P and Q is defined as
P×Q={(p,q):p∈P,q∈Q}

∴A×B={(7,5),(7,4),(7,2),(8,5),(8,4),(8,2)}
and B×A={(5,7),(5,8),(4,7),(4,8),(2,7),(2,8)}

1. Contract note is a confirmation of trade(s) done on a particular day for and on behalf of a client.

Marginal efficiency of capital are most closely associated with J.M. Keynes.

The act of transferring an entry or item from a book of original entry to the proper account in a ledger.

Given, Px=3 and Py=3, MRS=3

We know that a consumer is said to be in equilibrium when MRS=Px/Py. On substituting the above values, 3=3/3( that is MRS>Px/Py)

In this case the consumer is not in equilibrum. This implies that the consumer is willing to pay more for good X than the market requires. Thus the consumer will buy more and more units of X .As a result the MRS will fall due to law of diminishing marginal utility. This will continue till the MRS=Px/Py.

Progressive Tax – A progressive Tax is tax in which the tax rate increases as the taxable amount increases. The term ‘ Progressive’refers to the way the tax rate progressives from low to high, with the result that a tax payer’s average tax rate is less than the person’s marginal tax rate. In India income tax is a progressive tax. 

Proportional Tax – A Proportional Tax is a tax imposed so that the tax rate is fixed, with no change as the taxable base amount increases or decreases. The amount of the tax is in proportion to the amount subject to taxation. For example if the rate of income tax remains 20% whatever the size of income is, it will be a proportional tax.

(d) All of the above 

The three important features of Ricardian theory of rent are the following: 

(i) Rent is paid to land only. 

(ii) Rent is price paid for the use of original and indestructible powers of the soil. 

(iii) Rent is a differential surplus—the difference between the produce of the superior lands and marginal lands.

The conditions under which trade unions can raise wages are the following: 

(a) When wages are less than the marginal revenue productivity of labour, trade union can get wages raised up to the level of their marginal revenue productivity. 

(b) When higher wages results in raising productivity, the MRP curve of labour shifts to the right. In this situation, it is possible for the employers and trade unions to maintain the higher level of wage rate. 

(c) If the increase in costs due to higher wages can be passed on to the consumers in form of higher prices of the commodities, trade unions can raise the wages. 

(d) When the industry is earning abnormal profits, wages may be raised. 

(e) If the demand for a particular type of labour in an industry is inelastic, trade unions can easily get the wages raised.

Derived demand means the demand, which depends upon the demand of other goods and services. For example demand for labour is a derived demand, as it depends upon the demand of final goods produced by labour.

(d) All of these

Real wages refer to total quantity of goods and services that can be purchased by a worker with his money wages.

1. Direct personal observation; In this method the investigator, collects the required information by personal observation of the units, through the enumerator, from the informants. This methods is successively employed Where the field of enquiry is confidential, small, greater accuracy and sufficient time is available.

Merits: This method is most reliable, accurate and confidential. 

Demerits: This method is expensive, time consuming and this method becomes difficult where the enquiry is field of large. In this method there is chance of personal bias in collection of data, needs trained and skilled personnel.

2. Indirect oral interview: This method is applied, where the required information from the informant is not possible to obtain by direct interview method. In this method the investigator/enumerator approaches the witnesses or third parties, who are capable to supply the necessary information about the first person/informant.

Merits: This method is simple, convenient, free from bias and successively employed by News paper, Broadcasting, Investigating agencies. 

Demerits: In this method there is an ample scope of bias by influencing the enquiry by the third person.

Demand for labour depends upon the following factors: 

1. Marginal productivity of labour. 

2. Price of substitutes factors. 

3. Demand for the goods, which is being produced

Nominal wages are the payments made to labourers for their services in form of money or cash. If a worker gets Rs. 5000/- per month, it is an example of money wages.

Real wages refer to the total wages of a labourer that he gets in form of money and other facilities. Suppose a worker in addition to his money wage, gets some facilities like free education, medical facilities, subsidized houses etc, all this constitute his real wage.

The causes of wage differentials can be classified into two categories:

(a) Wage differentials between different occupations. 

(a) Difference in demand for goods: Demand for labour depends upon the demand for goods in the production of which they are employed. Demand for different commodities is not same. Difference in demand for different goods is an important factor that causes wage differentials. 

(b) Expenses on training: Larger the expenses on training, more is the wage and vice versa. 

(c) Supplementary income: Workers are ready to work at low wages in certain occupations where they can supplement their incomes compared to workers working in those occupations where there are fewer chances for them to supplement their incomes.

(d) Risk of life: In certain occupations, a great risk of life is involved. Therefore in such occupations, money wages are higher than the wages in less risky occupations. 

(e) Social status: The greater the respect a person enjoys the lower the wages at which he would be ready to work. So wages tend to vary from occupation to occupation. 

(f) Future prospects: Future prospects also vary from occupation to occupation. People are always ready to join occupations, where their future is bright at low wages.

(b) Wage differentials within the same occupation. 

(a) Differences in efficiency of labour: All labourers are not alike. They differ in their efficiency. More efficient workers get better wages as compared to less efficient workers. 

(b) Geographical mobility: Wages differ within the same occupation at different places. A worker earns much more in Delhi than at Kohima.

Correct option: D. Controlling

The following factors affect real wages: 

(i) Price level; 

(ii) Supplementary income; 

(iii) Nature of employment and 

(iv) Future prospects.

Labour is any type of human activity—physical or mental done with a view to earning a reward. 

Following are the characteristics of labour: 

(a) It is a human factor. 

(b) It is an active factor of production as other factors depend upon labour for their use. (c) Labour is perishable. It cannot be stored. 

(d) Labour is mobile. A labourer sells his labour not himself. 

(e) Labour cannot be separated from labourers. 

(f) The demand for labour is a derived demand. 

(g) Labour varies in efficiency.

1. Mining: Mines are dug below the earth’s surface to get ores. The ores are then refined to extract the valuable elements, such as metals, gems, minerals, etc. Some of the environmental impacts of mining include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from the mining processes. 

2. Deforestation: It is the clearance of a forest or stand of trees where the land is converted to a non-forest use, such as agriculture and construction of houses. It results in loss of habitat for many plants and animals living in the forest. It may also lead to extinction of plant and animal species.

Correct option: D. All of the above
