Question

If A and B are digits, then find the value of A + B from the following calculation:

• A. A + B = 4
• B. A + B = 5
• C. A + B = 6
• D. A + B = 7

Answer 1

The correct option is C A + B = 6

To find the values of A and B, we first calculate the sum of the given numbers.

Calculating 7896 + 4523 by the standard method, we get:


So, 7896 + 4523 = 12,419

Now, comparing this to the given calculation, we find:


Hence, the value of A and B are:
A = 2 and B = 4

∴ The value of A + B is A + B = 2 + 4 = 6
