Answer:
Contribution act of settling claims will be used
Step-by-step explanation:
The contribution which is one of the principles in insurance business means when two insurance company comes together to settle a claim on a subject matter they insured in common, according to the extent of peril covered under each policy.
In this case where the both policy from the two insurance company covers the same extent under the health insurance, they are going to share the claim amount equally (i.e. 50:50)
Say the total benefit to be paid as a result of permanent disability is $50000, in this scenario, Insurance company A will pay $25000 and Company B will also pay $25000. This is because both policies cover the insured with the same benefit and conditions.
