    If \[8-\left[ 7-\left\{ x-\left( 4-\frac{7}{7} \right) \right\} \right]=5,\] then the value of \[x\]is

    A) 7                     

    B) 4.5

    C) 3.2                               

    D) 2.5

    Correct Answer: A

    Solution :

    \[8-\left[ 7-\left\{ x-\left( 4-\frac{7}{7} \right) \right\} \right]=5\] \[\Rightarrow \]   \[8-[7-(x-3)]=5\] \[\Rightarrow \]   \[8-[7-x+3]=5\] \[\Rightarrow \]   \[8-10+x=5\] \[\Rightarrow \]   \[-\,2+x=5\] \[\Rightarrow \]   \[x=7\]
