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,

4∗x−5∗y=1/3∗4x

12∗x−15∗y=4x

8∗x=15∗y

Therefore, ratio of their savings=

(3∗x−4∗y)/(4∗x−5∗y)

=(3∗x−4∗8∗x/15)/(4∗x−5∗8∗x/15)

=(15∗3–8∗4)/(15∗4–5∗8)  

=13/20
