The correct answer is: A. actual time with standard time.
Labour productivity is a measure of the efficiency of labour, and is calculated by dividing the total output of a company by the total number of hours worked. It is a key indicator of a company’s efficiency, and can be used to compare the performance of different companies or to track a company’s performance over time.
Actual time is the time that it takes an employee to complete a task. Standard time is the amount of time that it should take an employee to complete a task, based on a set of predetermined standards. Labour productivity can be measured by comparing actual time with standard time, but this is not the most accurate way to measure it. This is because actual time can be affected by factors such as the employee’s skill level, the complexity of the task, and the availability of resources.
A more accurate way to measure labour productivity is to compare total output with total man hours. Total output is the total amount of goods or services that a company produces in a given period of time. Total man hours is the total number of hours that employees work in a given period of time. Labour productivity can be calculated by dividing total output by total man hours. This gives a more accurate measure of the efficiency of labour, as it takes into account the factors that can affect actual time.
C. added value for the product with total wage cost and D. total wage and total output are also ways to measure labour productivity, but they are not as accurate as comparing total output with total man hours. This is because they do not take into account the factors that can affect actual time.
