The manufacturing cost of an item is Rs3 per item, fixed cost is Rs900 and the labour cost is Rs `(x^2)/100` for x items produced. How many items must be produced to have average cost minimum.

The cost of manufacturing of certain items consists of Rs 600 as overheads Rs30 per item as the cost Rs x^2/100 of the material and the labour cost for x items produced. How many items must be produced to have average minimum cost.

The manufacturing cost of an item consists of rupes 100 as overheads , material cost rupes 2 per item and the labour cost ( x^(2))/(90) for x items , produced . Find the average cost.

For manufacturing a certain item, the fixed cost is 9000 and the variable cost of producing each unit is Rs 30. The average cost of producing 60 units is -

The cost function of a product is given by C(x)=(x^(3))/(3)-45x^(2)-900x+36 where x is the number of units produced. How many units should be produced to minimise the marginal cost ?
