Question

собачка спрятала косточку на школьном стадионе под зрительским креслом и .....забыла где.она помнит только,что в номере кресла есть цифра 9 и сумма цифр этого числа больше 11,но меньше 13.под каким номером спрятала собачка косточку,если на стадионе 90 кресел?

Answer 1

Сумма цифр 12. Число двухзначное, т.к. всего 90 мест. Вторая цифра 12-9=3. Т.к. число меньше 90, то это 39.

Answer 2

39                                                                         

Answer 3

The Dog and the Hidden Bone Puzzle

The puzzle states that a dog has hidden a bone at a school stadium under one of the spectator seats. The dog only remembers that the seat number contains the digit 9 and that the sum of the digits in the seat number is greater than 11 but less than 13. The stadium has a total of 90 seats. We need to determine under which seat number the dog has hidden the bone.

To solve this puzzle, we can follow these steps:

1. Determine the possible seat numbers that satisfy the given conditions. 2. Calculate the sum of the digits for each possible seat number. 3. Identify the seat number that matches the conditions.

Let's go through each step in detail.

Step 1: Determine the Possible Seat Numbers

The puzzle states that the seat number contains the digit 9. Since there are 90 seats in total, we can assume that the seat numbers range from 1 to 90. We need to identify the seat numbers that contain the digit 9.

The possible seat numbers that contain the digit 9 are: 9, 19, 29, 39, 49, 59, 69, 79, 89, and 90.

Step 2: Calculate the Sum of the Digits

Next, we need to calculate the sum of the digits for each possible seat number. We are looking for a sum that is greater than 11 but less than 13.

Let's calculate the sum of the digits for each possible seat number:

- For seat number 9: The sum of the digits is 9. - For seat number 19: The sum of the digits is 1 + 9 = 10. - For seat number 29: The sum of the digits is 2 + 9 = 11. - For seat number 39: The sum of the digits is 3 + 9 = 12. - For seat number 49: The sum of the digits is 4 + 9 = 13. - For seat number 59: The sum of the digits is 5 + 9 = 14. - For seat number 69: The sum of the digits is 6 + 9 = 15. - For seat number 79: The sum of the digits is 7 + 9 = 16. - For seat number 89: The sum of the digits is 8 + 9 = 17. - For seat number 90: The sum of the digits is 9 + 0 = 9.

Based on the calculations, the seat numbers that have a sum of digits greater than 11 but less than 13 are: 39.

Step 3: Identify the Seat Number

From the calculations, we find that the only seat number that satisfies the given conditions is 39. Therefore, the dog has hidden the bone under seat number 39.

So, the dog has hidden the bone under seat number 39.
