FROM 500 TO 1000​

Answer 1

sorry i don't know....

Answer 2

Answer:

Lets modify the problem a bit. Let's calculate the number of zeros in 0-9999. There will be just as many 0s in this range as 1s, 2s, and so forth. Thus 1/10 of all digits (including repetitions) will be zero. We have:

10 digits to 1 digit numbers.

2 x 90 = 180 digits to 2 digit numbers.

3 x 900 = 2700 digits to 3 digit numbers.

4 x 9000 = 36000 digits to 4 digit numbers.

Add up all of these and divide by 10 to get the number of zeros - it's 3889. Now, we need a small adjustment because our range is 1-10000. We deduct one 0 (because 0 isn't included) and add 4 0s (because 1000 is included).

Thus, we have 3892 zeros in the range.
