Question
Replace A, B, C by suitable numerals.
$\underline{ \ \ \ \ 4 \ \text{C B } \ 6\\+3 \ \ 6\ \ 9\text{ A}}\\ \ \ \ \ 8\ \ 1\ \ 7\ \ 3$
✓

Answer

A + 6 = 13
⇒ A = 16 - 6 = 7
So, 1 is carried over.
1 + B + 9 = 17
⇒ B = 17 - 10 = 7, B = 7 and 1 is carried over.
1 + C + 6 = 11
⇒ C = 11 - 7 = 4
$\therefore$ A = 7, B = 7 and C = 4.
