Answer: Adjustments will be made on the insured's new hazardous job, and he is covered according to the premium he has paid with relevance to how hazardous his new job is.
Explanation: Since there is a change of occupation clause to the policy, the insured was supposed to inform the insurer to make adjustments for his new occupation with regards to the nature of hazard involved. However the insured didn't do this, the insurer would make his investigations therefore and make his adjustments as necessary to cover the insured with premium paid for previous occupation. If the new occupation is more hazardous, the insured covers with the premium in hand and ignores deficits. On the other hand if new occupation is less hazardous, the insurer covers and also indemnifies the insured for any excess premium paid.
