Please try below code :- 
trigger AccountTrigger on Contact( after insert, after update)
	Set<String> setId = new Set<String>();
	for( Contact cont : trigger.New)
	Map<Id,Account> mapAcc = new Map<Id,Account>([select id,name,status__c from account where id in :setId ]);

	List<Account> listAccountToUpdate = new List<Account>();
	for( Contact cont : trigger.New)
			Account acc =mapAcc.get(cont.AccountId);
			acc.Status__C = cont.Status__c;
	if(listAccountToUpdate.size() >0)
		update listAccountToUpdate;

Hi v varaprasad,

Here I have a small query if you have 5 child with diffreent status which status you need to update in parent ?
You want to update status from parent to child or from child to parent ?

Hi V,

In this case trigger is not required, you can simply use process bulder to update parent status based on child status....

Please check and let me know if you haev any doubts.
