If AB + 7C = 102, where B ≠ 0, C ≠ 0, then A + B + C = 14.
True(T)
Here, we have
This implies B + C is either 2 or two digit number whose one’s
digit is 2.
Its given that B ≠ 0, C ≠ 0,so B + C is a two digit number whose one’s digit is 2.
When B = C = 1, then A should be 3 so that we have
But in this case A + B + C ≠ 14,so B = C = 1 cannot happen.
(I)Here either B or C should be 5 or 7 and A should be 3 so that
A + B + C = 14.
(II)If B = C = 6 and A = 2, then
and A + B + C = 14
