The sum of two numbers are 65,71,84
Smallest card number is 26
Smallest number (s) , middle number (m) , biggest number (b)
Sum can be derived from s+m , s+b , m+b
Smallest sum must be from s+m
So, 26+m = 65. Middle number is 65-26=39
Biggest sum must be from m+b
So, 39+b = 84. Biggest number is 84-39=45
To check, 45+26=71
