adrian and betty together teaches for 36 yrs...(adrian+betty=36)--------eq 1
betty and charlie together teaches for 22 yrs...(betty+charlie=22)-------eq2
charlie and adrian together teaches for 28 yrs...(charlie+adrian=28)-----eq3
now addind equation 1,2,3...we get....
2(adrian+beety+charlie)=86
now,(adrian+betty+charlie)=43--------eq 4
