Question

На доске написано число. Ребёнок играет в арифметическую игру: он может либо стереть последнюю цифру написанного числа, либо прибавить к написанному числу число 2017 и записать полученный результат, стерев предыдущее число. Может ли ребёнок, действуя таким образом, в конце концов получить число 3? Какое наименьшее пятизначное число может получиться, если на доске записано число 52? (В ответе запиши да или нет.)

Answer 2

Can the child eventually get the number 3 by following the given rules?

To determine if the child can eventually reach the number 3 by following the given rules, we need to analyze the possible outcomes of each operation (erasing the last digit or adding 2017) and see if any combination can lead to the number 3.

Starting with the number 52, let's consider the possible operations:

1. Erasing the last digit: If the child erases the last digit of 52, the resulting number is 5. However, this does not lead to the number 3.

2. Adding 2017: If the child adds 2017 to 52, the resulting number is 2069. Again, this does not lead to the number 3.

Based on these operations, it is not possible for the child to reach the number 3 starting from 52. Therefore, the answer is no.

What is the smallest five-digit number that can be obtained if the number on the board is 52?

To find the smallest five-digit number that can be obtained starting from 52, we need to consider the possible operations and their outcomes.

1. Erasing the last digit: If the child erases the last digit of 52, the resulting number is 5. However, this is not a five-digit number.

2. Adding 2017: If the child adds 2017 to 52, the resulting number is 2069. This is a five-digit number.

Therefore, the smallest five-digit number that can be obtained starting from 52 is 2069.
