तीन अंको की कुल 64 ऐसी संख्याएं होगी जिनमे 2, 5, 6, 8 न आये

Step-by-step explanation:

2,12,22,32,42,52,62,72,82,92 = 10 संखया

5,15,25,35,45,55,56,57,58,59 = 10

6,16,26,36,46,56,66,76,86,97 = 10

8,18,28,38,48,58,68,78,88,89 = 10

20,21,23,24,27,29 = 6

50,51,53,54,57,59 = 6

60,61,63,64,67,69 = 6

80,81,83,84,87,89 = 6

(10 × 4) + (6 × 4)

40 + 24

64
