If we write numbers from 1 to 100, the number of times the digit 5 has been written is
11
15
19
20
Answer
The digit 5 appears at the units place in: 5, 15, 25, 35, 45, 55, 65, 75, 85, 95 — that is, 10 times.
The digit 5 appears at the tens place in: 50, 51, 52, 53, 54, 55, 56, 57, 58, 59 — that is, 10 times.
Total number of times the digit 5 is written = 10 + 10 = 20.
Hence, option 4 is the correct option.
