Printing Jobs =4::::::::::::10::::::::3:::::::::::::14:::::::::::6::::::::::::::7::::::::::::::::9

Binding Jobs:::::8::::::::::::5:::::::::11:::::::::::14:::::::::::1::::::::::::::12::::::::::::::2

According to the Johnson rule smallest value from the both the jobs name is binding jobs is 1 hour

order sequence for binding

1,2,5 it means =X,Z, U

Then go for Printing Jobs find smallest and still the letters not occupied V T,W, Y

V= 3 hours is smallest followed by T with 4 hours, Y with 7 hours, W with 14 hours

Now scheduled order

V

T

Y

W,
