If AB × 4 = 192, then A + B = 7.

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
