The decimal d is formed by writing in succession all the positive integers in increasing order after the decimal point; that is d = 0.123456789101112
What is the 100th digit of d to the right of decimal point ? Choose the correct choice from the following.
A) 0
B) 1
C) 5
D) 8
E) 9
Now, let's see first we have those single digit numbers that occupy 9 spaces   Then the next integers from 10 to 19 will be 10 of them that will occupy 2 places each hence 20   The next ones will be from 20 to 29, 10 of them again, 2 places each hence 20 and so on   ...   Until we get to 50-59 which will be 10 integers again, 2 places each hence 20 digits.   Now the 100th digit will be in the 50-59 range taking into consideration the first 9 single digit integers.   We also know that the tenth digits is always in an even place while the units digit is in the odd place. Therefore, the 100th digit will be the tenth digit of the given range (50-59) thus 5   Answer is 5
