Answer:

410 is the answer

Step-by-step explanation:

subtract the two digits to get the left most digit of the solution. then add the two digits to get remainder of solution.

ex as we know 5-3=2 and 5+3=8 in the given question

5 + 3 = 28

The answer is 410.

How?

A+B =CD

C=(A-B) , D(A+B)

5 + 3 = (5-3)(5+3) = 28

9 + 1 = (9-1)(9+1) = 810

8 + 6 = (8-6)(8+6) = 214

similarly

7 + 3 = (7-3)(7+3) = 410
