A) 102  B) 103  C) 104  D) 105  E) 106
8 digit no, =11111111   7 digit no.= 1111112,1111121,1111211........= total 7 numbers   6 digit no. = 111113,111131...........111122,111221....= total 21 numbers   5 digit no.= 11114,11141........11123....11231.....=total 25 numbers   4 digit no.= 2222,1115,1151,1511,5111....1133.....1124....= total 22 numbers   3 digit no.= 116,161,611,224,242,422,332,323,233....125....134...= total 21 numbers   2 digit no. = 44,17,71,26,62,35,53 = total 7 numbers.   now total possible numbers are (without zero) = 104   ANSWER:104
