48. Having made 5 shots each at the target, Kolya and Petya scored $10,9,9,8,8,5$, $4,4,3,2$ points. With their first three shots, they scored the same number of points, and with their last three shots, Kolya scored three times more than Petya. How many points did each of them score with their third shot?
48. With three shots, one can score no less than 9 points (2+3+4=9) and no more than 28 (10+9+9=28). Since 9 * 3 = 27, it is clear that Kolya scored 10, 9, and 8 points with his last three shots, while Petya scored 4, 3, and 2. The remaining points 9, 8, 5, and 4 were scored with the first two shots. If Kolya scored 5 and 4 (5+4=9), and Petya scored 9 and 8 (9+8=17), then with the third shot, Kolya scored 10 (9+10=19), and Petya scored 2 (17+2=19). Other variants do not satisfy the condition. Thus, with the third shot, Kolya scored 10 points, and Petya scored 2.
