Lapunk mostanában minden számban - évente 9-szer - 8 gyakorlatot és 8 feladatot közöl. Feltéve, hogy ez változatlanul marad, mely számban várható annak a kitűzött feladatnak, valamint annak a kitűzött gyakorlatnak a megjelenése, amelynek sorszáma megegyezik a megjelenés évszámával?

Our journal currently publishes 8 exercises and 8 problems in each issue - 9 times a year. Assuming this remains unchanged, in which issue is the appearance of the problem and the exercise expected, whose number matches the year of publication?
a) In 1967, the last practical problem number was 1169, so by the end of the year, the lag of the $G y$ number behind the year number was 798. The lag decreases by $72-1=71$ each year. The integer part of the quotient of $798: 71$ is 11, with a remainder of 17. According to this, the lag of $G y$ decreases to 17 by the end of 1978. The integer part of the quotient of 17 : 8 is 2, with a remainder of 1, so under the assumption stated in the problem, the number of the second practical problem in the 3rd issue of 1979 will be 1979.

b) In the realm of problems, starting from the last, 1576th problem number in the December 1967 issue, it similarly follows that the number of the 5th problem in the 5th issue of 1973 will be 1973.
