Question 359545
It takes Jose 12 days to complete a task. The same task would take Hans 24 days.
After the two men work on the task for 4 days, Jose leaves for vacation and Hans
continues. In how many more days will Hans finish the work?
...
both together will do 1/12 + 1/24 of the job in 1 day

=3/24 = 1/8 of the job.
in four days they will complete 1/8 * 4= 1/2 the job.
...
balance 1/2 job Hans does alone
hans does 1/24 of the job in 1 day
to complete 1/2 job he will take (1/2) / (1/24)
12 days
