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

Answer

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