- Process 2: 2 hours
- Process 3: 1 hour
- Total Labour Content: 3 + 2 + 1 = 6 hours
Example 2:
- Process 1: 4 hours
- Process 2: 1 hour
- Total Labour Content: 4 + 1 = 5 hours
Example 3:
- Process 1: 2 hours
- Process 2: 3 hours
- Process 3: 2 hours
- Total Labour Content: 2 + 3 + 2 = 7 hours
Example 4:
- Process 1: 0.5 hours
- Process 2: 1.5 hours
- Process 3: 0.5 hours
- Total Labour Content: 0.5 + 1.5 + 0.5 = 2.5 hours
Example 5:
- Process 1: 3 hours
- Process 2: 2.5 hours
