Question

Replace A, B, C by suitable numerals:

$$\begin{gathered} \begin{array}{cccccc}7)& 6& A& B& (8& C\\ -& 5& 6& & & \end{array} \\ \overline{\underline{\begin{array}{ccc}& 6& B\\ -& 6& 3\end{array}}} \\ \times \end{gathered}$$

Answer 1

Here, $$\begin{gathered} A-6=6 \\ \Rightarrow A=2(\mathrm{with}1\mathrm{being}\mathrm{borrowed}) \end{gathered}$$
$B=3$
Since $7\times 9=63$, $C=9$
∴ $A=2,B=3andC=9$
