If AB × 4 = 192, then A + B = 7.
विकल्प
True
False
उत्तर
This statement is False.
Explanation:
AB
We have, × 4
192
Here, B × 4 is a two-digit number whose unit's digit is 2.
Therefore, the value of B is either 3 or 8.
But B = 3 is not possible as A × 4 + 1 ≠ 19 for any value of A between 0 to 9
∴ B = 8 and then A = 4
Hence, A + B = 12
