Sodium fusion extract of an organic compound $\displaystyle (\mathrm{Y})$ with $\displaystyle \mathrm{CHCl}_3$ and chlorine water gives violet color to the $\displaystyle \mathrm{CHCl}_3$ layer. $\displaystyle 0.15$ g of $\displaystyle (\mathrm{Y})$ gave $\displaystyle 0.12$ g of the silver halide precipitate in Carius method. Percentage of halogen in the compound $\displaystyle (\mathrm{Y})$ is $\displaystyle \_\_\_\_$. (Nearest integer) (Given : molar mass $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{Cl}: 35.5, \mathrm{Br}: 80, \mathrm{I}: 127$ )
