If AB × 4 = 192, then A + B = 7.
Answer :
False(F)
Here we have,
So,B×4 is a two digit number whose units digit is 2.
Therefore, the value of B is either 3 or 8.
But if B = 3,B×4 = 12 and A×4 + 1 ≠19,for any value of A between 0 to 9.
Therefore,B should be equal to 8,then B×4 = 32,
A × 4 + 3 = 19(when we multiply AB by 4, refer the above multiplication)
Hence,A×4 = 19-3 = 16
⇒ A = 4
Therefore,A = 4 ,B = 8,and A + B = 4 + 8 = 12
