Question:
If AB × 4 = 192, then A + B = 7.
Solution:
False
Explanation:
From the given question, the value of B should be either 3 or 8.
If you take the value of B is 3, it should be equal to 19.
Hence, the value of B is 8.
We know that, the value of A should between 0 and 9.
Hence, A x 4 = 19- 3 = 16
A = 16/4
A = 4
Therefore A= 4 and B= 8
Hence, A+B = 4+8 = 12
