@durgam santhosh,

This code is for before insert, before update:

trigger UpdateAccountFields on Account (before insert, before update) {
    // Get the set of Account Ids to be updated
    Set<Id> accountIds = new Set<Id>();
    for (Account acc : Trigger.new) {
        if (acc.Industry == 'Banking') {
            accountIds.add(acc.Id);
        }
    }
    // Retrieve the related Contacts
    Map<Id, Contact> contactsMap = new Map<Id, Contact>(
        [SELECT Id, LastName, Phone FROM Contact WHERE AccountId IN :accountIds]
    );
    // Update the Account fields based on the Contact details
    for (Account acc : Trigger.new) {
        if (acc.Industry == 'Banking' && contactsMap.containsKey(acc.Id)) {
            Contact contact = contactsMap.get(acc.Id);
            acc.Name = contact.LastName;
            acc.Phone = contact.Phone;
        }
    }
}
