Since the quantity which can be sold exceeded the production capacity, the company has been considering the use of sub–contracting production facilities. Accordingly, when tenders were floated, two contractors responded as under :

Contractor DS offers to produce upto a maximum of 17,500 units of EXE or 14,000 units of WYE in a year for the type of work done by department 1 of the company. The price charged by DS is Rs. 138 per unit EXE and Rs. 212 per unit of WYE. These prices included the cost of direct materials used in department 1 of the company.

Contractor DW can produce upto a maximum of 11,200 units of EXE and 7,000 units of WYE in a year for the type of work done by department 2 of the company. The price charged by DW is Rs. 150 per unit of EXE and Rs. 192 per unit of WYE. These prices included the cost of direct materials used in department 2 of the company.
Required :

(i) If the company does not wish to use the sub–contracting facility, which of the two products and in what quantity should be produced and sold by the company by using its own manufacturing capacity to earn maximum profit? Calculate the resultant maximum profit.
(ii) If the company wishes to produce either 38,500 units of EXE or 31,500 units of WYE by using sub–contracting facility. State which of the two products should be produced to maximise the profits. Calculate the resultant maximum profit.

The company estimates its sales for the next quarter to range between 5,500 units and 6,500 units, the most likely volume being 6,000 units. The manufacturing programme will match with the sales quantity such that no increase in inventory of finished goods is contemplated in the next quarter. The following price and cost changes will, however, apply to the next quarter :

– The price of direct material B will increase by 10%. There will be no change in the price of direct material A.
– The wage rates will go up by 8%. If the production volume increases beyond 5,500 units, overtime premium of 50% is payable on the increased volume due to overtime working to be done by the variable labour complement.
– The fixed factory and selling expenses will increase by 20% and 25% respectively.
– A discount in the selling price of 2% is allowed on all sales made at 6,500 units level of output. The selling price, however, will remain unaltered if the volume of output is below 6,500 units.
While operating at a volume of output of 6,500 units in the next quarter, the company intends to quote for an additional volume of 2,000 units to be supplied to a Government department for its captive consumption. The working capital requirement of this order is estimated at 80% of the sales value of the Government order. The company desires a return of 20% on the capital employed in respect of this order.
Required :

(i) Prepare a flexible budget for the next quarter at 5,500, 6,000 and 6,500 unit levels and determine the profit at the respective volumes.
(ii) Calculate the lowest price per unit to be quoted in respect of the Government order for 2,000 units.
