Answer:

This can be solved by substituting letter with their corresponding numbers.

A B C D E F G H I J K L
1 2 3 4 5 6 7 8 9 10 11 12

So let’s convert it in the given equations and see;

A + A = 1 + 1 = 2 = B,

B + B = 2 + 2 = 4 = D &

A + B = 1 + 2 = 3 = C

Therefore;

A + B + C + D = 1 + 2 + 3 + 4 = 10 = J

Answer = J
