A table of a production function shows the output for different amounts of labour (rows) and capital (columns). The total product schedule of labour with capital fixed at 4 units is read from:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → the column where capital takes the value 4
In such a table, labour runs down the rows and capital across the columns. Fixing capital at 4 means using the column where capital is 4 and reading down it as labour rises.
NCERT (2026-27): “3.3.1 Total Product … Let us again look at Table 3.1. Suppose capital is fixed at 4 units. Now in the Table 3.1, we look at the column where capital takes the value 4. As we move down along the column, we get the output values for different values of labour. This is the total product of labour schedule with K2 = 4. This is also sometimes called total return to or total physical product of the variable input. This is shown again in the second column of table in 3.2”
