Which of the following statements is INCORRECT?
Collecting primary data is not quite expensive both, in the terms of time and money.
This section provides a detailed explanation to identify the INCORRECT statement about primary data from the given options. We will analyze each statement based on the characteristics of primary data.
Primary data is raw information collected directly from the source for the first time. Researchers gather this data specifically for their study using methods like surveys, interviews, observations, or experiments. Because it's collected firsthand, it is often considered original and more tailored to the research needs.
By analyzing each option, we find that the statement claiming primary data collection is not expensive in terms of time and money is inaccurate. The process is typically resource-intensive.
Thus, the INCORRECT statement is: Collecting primary data is not quite expensive both, in the terms of time and money.

Consider the following LPP.:
Max Z = 15x 1 + 10x 2
Subject to the constraints
4x 1 + 6x 2 ≤ 360
3x 1 + 0x 2 ≤ 180
0x 1 + 5x 2 ≤ 200
