The sum of income of a b and c is 72000. A,b and c spends 80%, 85%and 75% of his income. Thhe ratio of their saving is 8:9:20. Find the income of a

Answer 1

Answer:

let income of a,b,and c be x,y and z respectively

ATQ,x+y+z=72000

money spent by a= 80%of x= 80x/100,

money saved by a=x-80x/100=20x/100

money spent by b=85%=85y/100

money saved by b=y-85y/100=15y/100

money spent by c=75%=75z/100=z-75z/100=25z/100

ratio is 8:9:20,

20x/100:15y/100:25z/100 =8:9:20

4x:3y:5z=8:9:20

then we get ,y=3x/2,

and z=2x

we have x+y+z=72000

x+3x/2+2x=72000

then x=16000rs
