A radioactive nucleus decays by two different process. The half life of the first process is $\displaystyle 5$ minutes and that of the second process is $\displaystyle 30$ s . The effective half-life of the nucleus is calculated to be $\displaystyle \frac{\alpha}{11} \mathrm{~s}$. The value of $\displaystyle \alpha$ is $\displaystyle \_\_\_\_$.
