Answer: Option B
Solution (By Examveda Team)
$$\eqalign{ & {\text{loss }}\% \cr & = {\left( {\frac{{{\text{Common Loss and Gain}}\% }}{{10}}} \right)^2}\% \cr & = {\left( {\frac{{12}}{{10}}} \right)^2}\% \cr & = \frac{{36}}{{25}}\% \cr & = {\text{1}}\frac{{11}}{{25}}\% \cr & = {\text{1}}\frac{{11}}{{25}}\% {\text{ loss}}{\text{}} \cr} $$This Question Belongs to Arithmetic Ability >> Profit And Loss
