Answer:
20
Step-by-step explanation:
From 0 to 10: 3 appears once in number 3
From 11 to 20: 3 appears once i.e in number 13
From 21 to 30: 3 appears twice i.e in number 23 and 30
From 31 to 40: 3 appears 10 times i.e in 31,32,33,34,35,36,37,38,39
From 41 to 50: 3 appears once i.e in number 43
From 51 to 60: 3 appears once i.e in number 53
From 61 to 70: 3 appears once i.e in number 63
From 71 to 80: 3 appears once i.e in number 73
From 81 to 90: 3 appears once i.e in number 83
From 91 to 99: 3 appears once i.e in number 93
Therefore the total number of times 3 appears in numbers from 0 to 99 is;
1+1+2+10+1+1+1+1+1+1=20
