Answer 2

Answer:

Let income of A and B be 3*x and 4*x respectively.

Their expenditures be 4*y and 5*y.

Thus, savings of A and B will be 3*x-4*y and 4*x-5*y respectively

Given situation is,

[math]4*x-5*y=1/3*4x[/math]

[math]12*x-15*y=4x[/math]

[math]8*x=15*y[/math]

Therefore, ratio of their savings=

[math](3*x-4*y)/(4*x-5*y)[/math]

[math]=(3*x-4*8*x/15)/(4*x-5*8*x/15)[/math]

[math]=(15*3–8*4)/(15*4–5*8)[/math]

[math]=13/20[/math].
