By trial and error method
since its told that last digit is 3 times the second digit
means last digit is multiplication of 3
so
Let the last digit be 9
1.the third is four less than the last=9-4= 5
2.the fourth is two less than the last = 9-2 = 7
3.The last number is also three times the second.
second digit=9/3=3
4. first digit = 9-7-1 =1
5.the last number is the sum of the first, second, and third = 1+3+5= 9
Hence all condition are satisfied
Hence 5 digits are 13579 answer Jan 23, 2015
