                John chooses a 5-digit positive integer and deletes one of its digits to make a 4-digit number. The sum of this 4-digit number and the original 5-digit number is 52713. What is the sum of the digits of the original 5-digit number?

    Solved it!!
Five options possible are:
1. abcde + abcd
2. abcde + abce
3. abcde + abde
4. abcde + acde
5. abcde + bcde
But as last digit of sum is 3 then only (1) is possible. (e + e – cannot be an odd number)
a must be 4 or 5
Then work out using 4 and 5. ‘a’ has to be 4.
47921
+4792 = 52713
So answer is 23 (4+7+9+2+1)
