A, B, C, and D are positive digits such that ABCD + BCD + CD + D + 377 = 2012. Find A + B + C + D
The closest I could find is:
1276 + 276 + 76 + 6 + 377 = 2011 ! [ 2012 does not work !]
Doesn't look as if it can work.
The sum on the lhs will be odd, (the digits sum is 4D + 7), and that can't equal the even number 2012.
