Answer 1

A number consists of two digits . sum of the digit is 9

possible numbers are:

18,27,36,45,54,63,72,81,90

if 9 is subtracted from the number the digits are reversed

18-9=9

27-9=18

36-9=27

45-9=36

54-9=45

63-9=54

72-9=63

81-9=72

the number is 54

because 54 is two digit number

sum of the digit is 9,5+4=9

if 9 is subtracted from the number the digits are reversed

54-9=45
