Question

How many times digit 6 is used while writing numbers from 501 to 700

Answer 1

For number between 600 to 700 :

Number of 6 at the units place = 10

Number of 6 at the tens place = 10

Number of 6 at the hundredth place = 100

For number between 501 to 599 :

Number of 6 at the units place = 10

Number of 6 at the tens place = 10

Hence, total number of 6 between (501 – 700)

= 10 + 10 + 100 + 10 + 10 = 140

mark me as the brqinliest answer if it jelps...
