let assume khalli's salary=300 and bali's= 100
then according to question
300 * (1+x/100) + 100* (1+y/100) = 400 * (1+5z/100) ............................(1)
300 * (1+y/100) + 100* (1+x/100) = 400 * (1+3z/100) ............................(2)

rewriting equation 1 and 2
3x + y = 20z.....................(3)
and
x + 3y = 12z......................(4)

solve equation 3 and 4 ; you will get y=2z and x= 6z
so x:y= 3:1

khali salary be K and bali salary be B .... & K=3B
xK/100+yB/100= 5z(K+B)/100
or
xK+yB=5z(k+B)
substituting K=3B
3x+y=4.5z------------1
yK/100+xB/100= 3z(K+B)/100
or
yK+xB=3z(k+B)
suibstituting K=3B
3y+x=3z.4--------------2
mutiply 1 by 3 and subtract 2
x=6z
multiply 2 by 3 and subtract 1
y=2z
x:y=3:1
