The correct option is
A 8329
To calculate A + B, we need to first calculate the values of A and B separately.
Now, we know that A = 1378 + 4586
So, calculating 1378 + 4586 using the standard method, we get:

Hence, A = 5964
It is given that B = 7352 - 4987
Calculating 7352 - 4987 using the standard method, we get:

Hence, B = 2365
So, A = 5964 and B = 2365
∴ A + B = 5964 + 2365
Calculating 5964 + 2365 by the standard method, we get:
