Topic: To find all remaining three-digit numbers
Example. We take, for example, 250 and it is attributed to it 2. We receive 2250. 2250 in 9 times more 250. It is necessary to find all remaining three-digit numbers, at attributing to which in the beginning any digit, the received result would be in 9 times more initial number. Direct search and generally programming do not roll. The common decision is necessary.
