In the following correctly worked addition sum, A,B,C and D represent different digits, and all the digits in the sum are different. What is the sum of A,B,C and D?
If we take that A, B, C and D CANNOT take values of 5, 4 and 3 then we get (A, C) = (1, 2) or (2, 1) ; B=9 and D=1
Hence, A+B+C+D=13 !!

If two or more thoughts intersect with each other, then there has to be a point.
