A) Q = 5
B) Q = 4
C) Q = 3
D) Q = 6
Correct Answer: A
Solution :
\[256\div 45\] \[256\div 45\]rounds to \[200\div 40\] \[40\times 5=200\] So \[45\times 5=225<256\] Therefore, \[45\overset{5}{\overline{\left){\begin{align} & \,\,\,\,256 \\ & \underline{-225} \\ & \,\,\,\,\,\,\,31 \\ \end{align}}\right.}}\]
