Read Solution (Total 1)
-
- let salaries are x,y,z with respective A,B,C
saving of A=20%=.2x
saving of b=15 %=.15 y
saving of c=25 %=.25z
so .2x:.15y=8/9(given)
y=1.5x
and ,2x/.25z=8/20
z=2x
in question given x+y+z=1440
x+1.5x(y)+2x(z)=1440
x=320
so salary of b y=1.5x=480 rs ans - 10 years agoHelpfull: Yes(6) No(2)
