The cycloalkene $\displaystyle (\mathrm{X})$ on bromination consumes one mole of bromine per mole of $\displaystyle (\mathrm{X})$ and gives the product $\displaystyle (\mathrm{Y})$ in which $\displaystyle \mathrm{C}: \mathrm{Br}$ ratio is $\displaystyle 3: 1$. The percentage of bromine in the product $\displaystyle (\mathrm{Y})$ is $\displaystyle \_\_\_\_$ %. (Nearest integer) (Given : molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{H}: 1, \mathrm{C}: 12, \mathrm{O}: 16, \mathrm{Br}: 80$ )
