If AB + 7C = 102,
Question:

 If AB + 7C = 102, where B ≠ 0, C ≠ 0, then A + B + C = 14.

Solution:

True

Explanation:

From the given number, B+C is either 2 or the two digit number that gives the unit digit as 2.

It is given that B ≠ 0, C ≠ 0,

If B or C = 5 or 7, then A should be 3, then it becomes A+B+C = 14

Or else, if B= C = 6, and A = 2, we will get A+B+C = 14
