Use graphical method to minimise the time added to process the following jobs on the machines shown: 

 Calculate the total time elapsed to complete both the jobs.

To minimize the time added to process both jobs, we can use the Johnson's rule, which is a heuristic method to minimize the makespan of a set of jobs on two machines. The Johnson's rule involves the following steps:

1. Find the minimum processing time among all jobs on both machines.
2. Determine which machine the job with the minimum processing time belongs to. If the job belongs to Machine 1, it is scheduled first; if it belongs to Machine 2, ______ _________ ___ _______ __________ ___ __________ _____ _______.
