Question

Replace A, B, C by suitable numerals.
$$\begin{gathered} \begin{array}{cccccc}6)& 5& A& B& (9& C\\ -& 5& 4& & & \end{array} \\ \overline{\begin{array}{cccc}& & 3& B\\ & -& 3& 6\end{array}} \\ \overline{\underline{\begin{array}{ccc}& \times & \end{array}}} \end{gathered}$$

Answer 1

$(A-4)=3\Rightarrow A=7$
​Also, $6\times 6=36\Rightarrow C=6$
$36-36=0\Rightarrow B=6$

∴ $$\begin{gathered} A=7 \\ B=C=6 \end{gathered}$$
