Question 663503
The sum of my digits is 13. My hundreds place is 3 less than 5. My ones place is 4 more than 3. My thousands place is even. What 4-digit numbers can I be?
-----
Let the number be abcd
Equations:
a + b + c + d = 13
b = 2
d = 7
a = 2x
--------
Substitute:
2x + 2 + c + 7 = 13
2x + c = 4
--
Since 2x is even, x = 1 and c = 2
---
Ans: 2227
