Consider the following frequency distribution: If the sum of all frequencies is 584 and median is 45, then |α-β| is equal to \ \ \ \.

Consider the following frequency distribution :

Class:	$\displaystyle 10$-$\displaystyle 20$	$\displaystyle 20$-$\displaystyle 30$	$\displaystyle 30$-$\displaystyle 40$	$\displaystyle 40$-$\displaystyle 50$	$\displaystyle 50$-$\displaystyle 60$
Frequency:	$\displaystyle \alpha$	$\displaystyle 110$	$\displaystyle 54$	$\displaystyle 30$	$\displaystyle \beta$

If the sum of all frequencies is $\displaystyle 584$ and median is $\displaystyle 45$ , then $\displaystyle |\alpha-\beta|$ is equal to \_\_\_\_.
