Sector questionnaire in php mysql

Here I see how many questions you have in each industry:

SELECT 
    a.area_id   AS ID_AREA,
    a.area_desc AS AREA_DESC,
    count(sb.sub_area_cod) AS TOTAL  
      FROM
        relacaoperg AS rp
         INNER JOIN area     AS a  ON rp.id_area = a.area_id 
         INNER JOIN sub_area AS sb ON rp.id_subgrupo =  sb.sub_area_cod
              WHERE 
                   id_area <> '1' GROUP BY AREA_DESC ASC;

Returns as follows:

id  desc        total
2   FRENTE      18
3   FRIOS       36
4   ACOUGUE     35
5   MERCEARIA   27
6   HORTIFRUTI  31
7   PADARIA     33

Here are the answers:

SELECT 
       a.area_id   AS ID_AREA,
       a.area_desc AS AREA_DESC,
       count(resp_area) AS TOTAL 
             FROM respostas as r 
               INNER JOIN area     AS a  ON r.resp_area     = a.area_id 
               INNER JOIN sub_area AS sb ON r.resp_subgrupo =  sb.sub_area_cod
                  WHERE 
                    resp_area <> '1' 
                    AND resp_questionario='3' 
                        GROUP BY resp_area;

Returns as follows:

id  desc       total
3   FRIOS      32
5   MERCEARIA  27

That is only cold cuts and groceries that responded.

In the part of the select where I put: resp_area <> '1' this sector is the management.

I need the manager to only be able to respond when the answers are the same (same quantity), ie, he can only respond when all sectors have already answered.

How could you create this rule?
