A) \[\times ,\,=,\,\times ,\,+\]
B) \[\div ,\,=,\,\times ,\,\div \]
C) \[\div ,\,\times ,=,\,\div \]
D) \[\div ,\,\times ,+,\,=\]
Correct Answer: B
Solution :
Solving from the choices [A] Inserting the operators \[(\times ,=,\times ,+)\]. We get, \[169\times 13=13\times 13+13\] [Use BODMAS' rule] [B] Inserting the operators \[(\div ,\,=,\,\times ,\,\div )\] We get, \[\underline{\mathbf{169\div 13=13\times 13\div 13}}\]| [Use 'BODMAS rule] \[13=13\] [C] Inserting the operators \[(\div ,=,\times ,\div )\]. We get, \[169\div 13\times 13=13\div 13\][Use BODMAS' rule] \[13\times 13=1\Rightarrow 169\ne 1\] [D] Inserting the oprators \[(\div ,=,\times ,\div )\] We get, \[169\div 13\times 13+13=13\] [Use BODMAS' rule] \[13\times 13+13=13\Rightarrow 169+13=13\] \[\Rightarrow \,\,\,\,182\ne 13\]
