Rodolpho can complete the job in 8 days
Therefore, in 1 day Rodolpho can do 1 / 8 th work.
In 2 days Rodolpho will complete 2 * 1 / 8 = 1 / 4 work
Therefore, amount of work let to be completed = (1 - (1 / 4))= 3 / 4
After 2 days, Mortimer joins.
Mortimer can complete the work in 5 days.
In 1 day Mortimer can complete 1 / 5 work.
In 1 day Mortimer and Rodolpho can complete[ ( 1 / 8 )+( 1 / 5 ) ] 13 / 40 th work
13 /40 work in 1 day
so, 3/ 4 work can be completed in ( 3 / 4 ) / (13 /40) days
or, 3/ 4 work can be completed in 2.308 days
Rodolpho had completed 1 / 4 work in 2 days and both combined completed the remaining in 2.308 days.
Therefore, the total number of days taken to finish processing the loans is 2 + 2.307 = 4.308 days
