First of all we need to convert this problem into 4 jobs and 2 machines problems.
Min time on machine M₁ =min {M₁} = 5
Min time on machine M₅ = min {M₅} = 6
Max time on rest of machines = Max {M₂, M₃, M₄} =6
If min {M₁} or min {M₅} ≥ Max {M₂, M₃, M₄} then this problem can be converted into 4 jobs into 2 machines (say N₁ and N₂)
As above condition is satisfied so the new table:
N₁ = time (M₁ + M₂ + M₃ + M₄) on each jobs
N₂ = time (M₂ + M₃ + M₄ + M₅) on each jobs

According to Johnson’s rule the job sequence is as follows:
