A computer generates a series of five-digit product codes according to the following rules:
The codes use the numerals 0, 1, 2, 3, 4, and no others.
Each numeral occurs exactly once in any code.
The second digit in the code has a value exactly twice that of the first digit.
The value of the third digit in the code is less than the value of the fifth digit.
If the fifth digit of an acceptable product code is 1 then it must be true that the: аться
The value of the third digit in the code is less than the value of the fifth digit.
If the fifth digit of an acceptable product code is 1 then it must be true that the:
a) first digit is 2
b) second digit is o
c) third digit is 3
d) fourth digit is 4
e) fourth digit is o

Since the value of second digit has a value exactly twice that of the first digit, the second digit must be 4 and the first digit must be 2 (There are no other two numbers that are multiple of 2).

Since the value of the third digit is less than the value of the fifth digit, the third digit must be 0 (fifth digit is 1) and forth digit must be 3.

The code is: 2 4 0 3 1
