Question

In a city,there are 1000 light poles.A government official is asked to number the light poles from 1 to 1000 at the time of a survey.How many zeroes will he need?(plss give the complete solution with explanation)

Answer 1

Number of zeros needed = total number of zeros between 1 to 1000
Number of zeros between:
1 - 100 = 11
101 - 200 = 20 
201 -300 = 20 
301 - 400 = 20 
401 - 500 = 20 
501 - 600 = 20 
601 - 700 = 20 
701 - 800 = 20 
801 - 900 = 20 
901 - 1000 = 21

Total number of zeros = 192 zeroes
