What is the ratio of the total demand to the total production of both companies?
Answer: D
Total Demand = Demand of A + Demand of B = 6000 + 5500 = 11500 tonnes.
Total Production = Production of A + Production of B = 5000 + 6000 = 11000 tonnes.
Required Ratio = Total Demand : Total Production = 11500 : 11000.
Dividing both by 500 gives the ratio 23 : 22.
