Answer:
The total amount to be paid = $18000
Step-by-step explanation:
Arthur: $10000
Fred: $8000
Total: $18000
The numbers 10/20 means 10 stands for $10000 and 20 stands for $20000. In total $20000 will be given to all persons.
So, Fred will get a maximum of $10000, but his bill is $8000, so he will get $8000. And Arthur will get $10000 as this is liability limit. So, both will get a total of $18000.
