Let J = Jan's salary, Y = Jani's salary, and S = Sam's salary:
 
J/Y = 3/4  Therefore 4J/3 = Y               [Jan and Jani's salary ratio = 3/4]
 
J/S = 2/3; Therefore 3J/2 = S              [Jan and Sam's salary ratio = 2/3]
 
J + Y + S = $1800                               [Total salary = $1800]
 
Substitute:
 
J + Y + S = $1800
J + 4J/3 + 3J/2 = 1800
23J/6 = $1800
J = $1800*6/23
 
J = $469.57
 
Find Y and S:
 
Y = 4J/3 = 4*($469.57)/3 = $626.09
S = 3J/2 = 3*($469.57)/2 = $704.35
 
Check:
 
 J + Y + S = $1800
 $469.57 + $626.09 + 704.26 = $1800

They add up to $1800. I worked it out using Philip's solution. Check your work.
