    Step-by-step explanation:

    Given that,

    The ratio of chair to table is 12:7

    C:T=12:7

    Total ratio = 12+7 = 19

    Chair ratio = 12

    Table ratio = 7

    If there are 84chairs

    Then,

    Number of chairs=chair ratio / total ratio * total number of chair and table.

    Let total number of chair and table be y

    84=12/19 * y

    84=12y/19

    84*19=12y

    y=84*19/12

    y=133 chairs and tables

    Chairs + table = total chair and table

    84+table=133

    Table=133-84

    Table = 49

    Therefore there are 49 tables

    Alternatively,

    Number of table=table ratio / total ratio * total number of chair and table.

    Table=7/19 * 133

    Table=931/19

    Table=49

    So there are 49 tables in the restaurant
