Raw materials .X. costing Rs. 100 per kg and Y costing Rs. 60 per kilogram are mixed in
equal proportions for making product A. The loss of material in processing works out to
25% of the output. The production expenses are allocated at 50% of direct material cost.
The end product is priced with a margin of 331/3% over the total cost. Material Y is not
easily available and substitute raw material .Z. has been found for .Y. costing Rs. 50 per
kg. It is required to keep the proportion of this substitute material in the mixture as low as
possible and at the same time maintain the selling price of the end product at existing
levels and ensure the same quantum of profit as at present.
You are required :
To Compute what should be the ratio of mix of the raw materials X and Z.
