The decimal d is formed by writing in succession all the positive integers in descending order after the decimal point; that is d = 0.15141312111098765
What is the 19th and 20th digits of d to the right of decimal point?  Options.
A) 32	B) 43	C) 54	D) 12	E) 21
The descending order of numbers begins with 15.   0.15141312111098765   So, 15, 14, 13, 12, 11, 10, ...,(first 12 digits are 2 digit numbers).   Then, 9, 8, 7, 6, 5, ...,(next 5 digits are single digit numbers).   It follows that 4, 3, and 2 are the next digits, thus 3 and 2 are the 19th and 20th digits, respectively.   32nswer: 32
