2 subsets (Posted on 2020-05-13) Difficulty: 2 of 5
AB+C=DE
KL+MN=PM
A+D=17

(a). Distinct letters in the above equations should be replaced by appropriate digits to make the three equations true.
(b). There are 252 possible ways to divide (0,1,2,...,9) into two disjoint subsets: Set 1: A,B,C,D,E and Set 2: K,L,M,N,P.
(c). Since B will be interchangeable with C and L with N, there exist 4 choices of solutions that comply with (a).

List all four.

To make the solution unique:

Both F8667832 4685 & 7832U4 4685
must have the same meaning.

Good luck!
