A, B, C, and D are positive digits such that ABCD + BCD + CD + D + 377 = 2012. Find A + B + C + D
Maybe you mean the answer is 2011 or plus 378
I am stuck at that A, B, C, D might be
A = 1
B = 3
C = 1
D = 1,
1311 + 311 + 11 + 1 = 1634, 1634 + 377 = 2011 (2012 for 378)
A + B + C + D = 1 + 3 + 1 + 1 = 1 + 2 + 2 + 1 = (1 * 2) + (2 * 2) = 6 xD
