Which expression stands for 32 more than a number d

32 + d is the equation in this given question or the word problem in mathematical form.

For example:
Given:
A+B+C = 47
B+C+D = 53 
A+C+D = 55
A+B+D = 49

Notice that in the given equations, each of the variables is mentioned three times. So if get the total of all given equations we may get thrice the value of a set of variables
 (A+B+C+D). (A+B+C+D)+ (A+B+C+D) + (A+B+C+D) = 204
3(A+B+C+D) = 204 
A+B+C+D = 68 

The sum of all variables is 68. If we subtract the given equation, which has one missing variable, from the value of the set computed, we may get the value of the missing variable.
(A+B+C+D) -     (A+B+C)           = D
           68 -       47                     = D      
                        21                     = D
(A+B+C+D) -     (B+C+D)           = A    
           68 -       53                     = A                                 
                        15                     = A
 (A+B+C+D) -     (A+D+C)           = B             
            68 -       55                     = B                    
                         13                     = B
 (A+B+C+D) -     (D+A+B)           = C  
            68 -       49                     = C
                         19                     = C

The first option would be correct if it were one half and not one
