Solution:
To calculate the average variable cost of 4 units of output, we need to first calculate the variable cost at 4 units of output, which is the total cost minus the fixed cost. Then, we can divide the variable cost by the number of units produced to get the average variable cost.

Using the information provided in the table, we can calculate the variable cost at 4 units of output as follows:
Fixed cost = ₹240
Total cost at 4 units of output = ₹540
Variable cost at 4 units of output = Total cost at 4 units of output - Fixed cost
= ₹540 - ₹240
= ₹300
Therefore, the average variable cost of producing 4 units of output is:
Average variable cost = Variable cost at 4 units of output / 4 units
= ₹300 / 4
= ₹75
So the average variable cost of producing 4 units of output is ₹75.
Correct option is (a)
