Answer 2

Problem:

The task is to write the names of the children on calendar sheets in such a way that all statements are correct. The given information is as follows: 1) Mykola, Petro, Tetiana, and Nina were born in 2007. 2) Tetiana is 2 days older than Mykola. 3) Petro was born in April. 4) Nina is older than Mykola. 5) Tetiana is younger than Petro.

Solution:

To solve this problem, we need to analyze the given information and determine the correct birth dates for each child. Let's go through each statement and find the correct arrangement of names and birth dates.

1) Mykola, Petro, Tetiana, and Nina were born in 2007. - Since all children were born in 2007, we can assign the birth year 2007 to each of them.

2) Tetiana is 2 days older than Mykola. - Based on this statement, Tetiana's birth date should be 2 days before Mykola's birth date.

3) Petro was born in April. - Petro's birth month is April.

4) Nina is older than Mykola. - Nina's birth date should be before Mykola's birth date.

5) Tetiana is younger than Petro. - Tetiana's birth date should be after Petro's birth date.

Now, let's arrange the names and birth dates based on the given information:

- March 23: Mykola - April 23: Petro - March 21: Tetiana - April 4: Nina - April 19: Not assigned yet

We have assigned birth dates to four children, but we still need to assign a birth date to Nina. To do this, we need to consider the remaining available date, which is April 19. Since Nina is older than Mykola, we can assign April 19 as Nina's birth date.

Therefore, the final arrangement of names and birth dates is as follows: - March 23: Mykola - April 23: Petro - March 21: Tetiana - April 4: Nina - April 19: Not assigned yet

Note: The birth date for the fifth child is not specified in the given information.
