A four-step production process has attrition Losses at the second and third resources. The percentage of loss is 20% at the second resource and 30% at the third resource the capacities of the resources are as follows:

Resource a: 240 units/hour

Resource b: 240 units/hour

Resource c: 190 units/hour

Resource d: 190 unit/hour

Given that we want a good output of 100 units per hour of the final product at the end of the process what should the minimum capacity in good units per hour for each individual resource
