Variable costs are always relevant and fixed costs are alway

Solution

I totally disagree with the aforementioned statement.

Variable costs are those which vary directly with the quantity produced of the comodity.

Whereas, Fixed costs are those which remain constant (fixed) at all levels of production.

In producing a product, both the cost i.e Fixed Cost and Variable cost are relevant for calculating the total cost of the product.

So, neither of them can be called relevant or irrelevant.
