Explanation

The Value of the total output in the economy will be gotten by adding all the values of the output and subtracting its intermediate consumption (the goods and services used to produce the output) to derive its value-added. That means, output - input

Value of output = 10 + 12 + 15 + 20 - (10 + 12 + 15)=

57 - 37 = 20

Correct Answer: A) Profits

Explanation

Profits are the financial gains that a business or individual receives from their investments or activities. It is the excess of revenue over expenses. In other words, it is the money that is left after deducting all costs and expenses.

Salaries are fixed regular payments made to employees for their work. It is usually paid on a monthly basis and is determined by factors such as job position, level of experience, and the company's salary structure.

Wages, on the other hand, are payments made to workers for the hours they have worked. It is usually based on an hourly rate or a piece-rate system, where workers are paid for the number of units they produce.

Allowances are additional payments made to employees to cover specific expenses or provide extra benefits. For example, travel allowances may be given to cover transportation costs, or housing allowances may be provided to help with accommodation expenses.

Now, looking at the options, the correct answer is Option A: Profits. Profits are not directly given as a reward for labor. Instead, profits are the returns earned by the owner or the shareholders of a business. Profits are generated from the revenue generated by the business, after deducting all expenses including labor costs.

To summarize, profits are not a direct reward for labor, but rather the returns earned by the owners or shareholders of a business. Salaries, wages, and allowances are the more direct rewards for labor.

Note: It is important to understand that in some cases, employees may also receive a share of the profits in the form of bonuses or profit-sharing schemes. However, this is not the primary or guaranteed reward for their labor.
