A can complete a work in $x$ days, and B can complete the same work in $2x$ days. A starts the work and works for $\frac{22}{9}$ days, after which B replaces him and finishes the remaining work in the same time as C and D together would take to complete it. The efficiency ratio of C to D is $4 : 5$. If C and D work on alternate days starting with C, they complete the entire work in $44\frac{1}{2}$ days.

E and F together work for 24 days, after which they are replaced by A and B respectively, who complete the remaining work in 20 days. The efficiency ratio of E to F is $5 : 4$. If E and F together complete the entire work alone, what is the difference between the amount of work done by E alone and the amount of work done by F alone?

Find the correct answer.
