Answer 1

Кресел - ?

Диванов - ?, на 10 меньше,чем кресел               ) на? кресел больше, чем столов

Столов - 12, на 5 меньше, чем диванов

 

12+5=17(диванов)

17+10=27(кресел)

27-12=15(кр) - на 15 кресел больше, чем столов

Answer 2

столы -12 штук

диваны-на 5 шт.больше ,чем столов

кресла-  на 10 штук больше, чем диванов

 

 

1) 12+5=17(шт)-диванов

2)17+10=27(шт)-кресла

3)27-12=15(шт)-на 15 штук кресел больше,чем столов

Answer 3

Analysis and Solution

To answer the given questions, let's break down the information provided:

- The number of sofas (divans) is 10 less than the number of armchairs (kresla). - The number of sofas is 5 more than the number of tables (stoly). - The number of tables is given as 12.

Now, let's calculate the number of armchairs and sofas based on the given information.

Calculation

Let's assume the number of tables (stoly) is represented by "T," the number of armchairs (kresla) is represented by "A," and the number of sofas (divans) is represented by "S."

From the given information, we can form the following equations:

1. The number of sofas is 10 less than the number of armchairs: S = A - 10. 2. The number of sofas is 5 more than the number of tables: S = T + 5. 3. The number of tables is given as 12: T = 12.

Now, let's solve these equations to find the values of A and S.

Substituting the value of T from equation 3 into equation 2, we get:

S = 12 + 5.

Simplifying, we find that:

S = 17.

Substituting the value of S from equation 1 into equation 2, we get:

A - 10 = 17.

Simplifying, we find that:

A = 27.

Answer

Based on the given information, we can conclude the following:

1. The number of armchairs (kresla) is 27, which is 15 more than the number of tables (stoly). 2. The number of sofas (divans) is 17. 3. The number of armchairs (kresla) is 27, given that there were 12 tables (stoly).
