I am a 5 digit number.
All my digits are odd.
The sum of the 5 digits is 25.
The digits in the ten thousands place and ones place make 10.
The ones digit is 4 more than the ten thousands digit.
The digits in the thousands place and tens place make 10 too.
The tens digit is 8 more than the thousands digit.
If none of the digits is repeated, what is the 5 digit number?
Odd digits: 1, 3, 5, 7, 9

Let the number be ABCDE.
A + B + C + D + E = 25
A + E = 10
E = A + 4
A + A + 4 = 10
2 A = 10 - 4 = 6
2 A = 6 ÷ 2 
A = 3
E = 10 - 3 = 7

Odd digits left: 1, 5, 9

1 + 9 = 10
B + D = 10
D = B + 8
B + B + 8 = 10
2 B = 10 - 8 = 2
B = 2 ÷ 2 = 1

D = 1 + 8= 9

Only odd digit left = C = 5

Number = 31597

Answer(s): 31597
