HCR's Rank Formula-2 (Rank of Selective Linear Permutations)/ proposed by H. C. Rajpoot /20/11/2014

Find out the total 8-digit numbers lying between 20227702 & 75007007 randomly selected from the set of all the 8-digit numbers, arranged in increasing order, obtained by the digits 0, 2, 5 & 7. Repetition of the digits is allowed in the permutations.

HCR's Rank Formula-2 (Rank of Selective Linear Permutations)/ proposed by H. C. Rajpoot /20/11/2014 Find out the rank in the increasing order of a randomly selected number 58014408 from the set of all the 8-digit numbers, arranged in increasing order, obtained by the digits 0, 1, 4, 5, 8, 9. Repetition of the digits is allowed in the permutations.
