In view of the substantial increase in material costs, the company explored the posibilities of using a substitute material. The company has been able to identify a cheaper source of direct materials which will cost Rs. 40 per unit of output. The tests reveal that the use of cheaper direct material as above will make the following impact on the costs:

– the direct labour cost will increase by Re. 1 per unit of output.
– it will lead to 5% rejection in output.
– it will result in a final quality testing programme evaluating an additional fixed cost of Rs. 4,00,000.
The selling prices are estimated as under for different levels of sales volume for the next year :

Selling price per unit (Rs.) :

Required :

(ii) Considering the range of selling prices estimated at different volumes of output, determine the selling price which will maximise the profit if : (A) regular direct materials are used and (B) cheaper direct materials are used.
(iii) Calculate for the price selected by you in (ii) above, the amount of fixed cost at which the company will be indifferent in choice of direct materials.
