Answer:
Total number of tables of first type       = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables. 
Let's call the two seat tables, the first type as x and the second type as y.
 ∴                                             x + y = 30                        ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
                                             2x + 5y = 81                        .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
                                                       y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind         = 23
   The number of tables of second kind   = 7
