Question

A child wrote 1 to 366 serially in his notebook. What is the total number of digits he had written?

Answer 1

total number of digits are 990 if 1 to 366 are written serially.

Step-by-step explanation:

A child wrote 1 to 366 serially in his notebook

1 to 9 - 9 digits

10-99 = 90×2 = 180 digits

100 - 366 = 267×3 = 801 digits

total digits = 9 + 180+ 801

= 990 digits

total number of digits are 990 if 1 to 366 are written serially.

Answer 2

Answer:

Step-by-step explanation:

1 to 9 = 9 digits

10 to 99 = 90*2= 180 digits

100 to 366 = 267*3= 801 digits

Total = 9+180+801 = 990 digits
