    A carpenter cuts a 13 m long board into length \[1\frac{3}{4}\]m,\[2\frac{2}{3}\]m,\[3\frac{1}{6}\]and\[4\frac{1}{2}\]m. How much board will be remaining after cutting the pieces?

    A) \[\frac{11}{12}m\]        

    B)   1 m

    C) 2 m                              

    D) 3 m

    Correct Answer: A

    Solution :

    Total length the carpenter cuts \[=\left[ 1\,\,\frac{3}{4}+2\,\,\frac{2}{3}+3\,\,\frac{1}{6}+4\,\,\frac{1}{2} \right]\,\,m\] \[=\frac{145}{12}\,\,m\] now, board will be remaining, after cutting the pieces    \[=13-\frac{145}{12}m\] \[=\frac{156-145}{12}m\] \[=\frac{11}{12}m\]
