    Solution :

    (c) Out of 8 parts, seven is shaded \[\Rightarrow \]\[\frac{7}{8}\times 100%=87\frac{1}{2}%\] Mind of a mathematician: Mathematical Ingenuity: \[1=100%\] \[{}^{1}/{}_{8}=12\frac{1}{2}%\] \[\therefore \]\[{}^{7}/{}_{8}=1-\frac{1}{8}=87\frac{1}{2}%\] This calculation should happen automatically to a thoughtful student.
