Number of companies = 2
| Average demand of companies B and D = | = | = 900 | Number of companies | 2 |
Sum of production of companies B and D = 2700 + 1800 = 4500
Number of companies = 2
| Average production of companies B and D = | Number of companies |
| Average production of companies B and D = | = 2250 | 2 |
∴ Required ratio = 900 : 2250 = 2 : 5
