Question

how many numbers are there between 100 and 1000 such that at least one of the digit is 7 (4 mark question) ​

Answer 1

Answer:

Numbers between 100 and 1000=900

Numbers between 100 and 1000 which do not have digit 7 at any place =8×9×9=648

Therefore,

Numbers between 100 and 1000 which have at least one digit as 7=900−648=252

Hence there are 252 numbers in between 100 and 1000 such that at least one of their digit is 7.
