Answer 2

Answer:

5 : 3

Step-by-step explanation:

Let A's income = 4x & B's income =3x

Let A's expenditure as 5y and B's expenditure as 4y

by solving A's expenditure we get,

A's expenditure =3/4 (4x) = 3x.

Savings: A's savings = 4x - 5y = x

B's savings = 3x - 4y.

                     3x - 4 (3x/5)

                     3x/5

        x : 3x/5

      5x : 3x

        5 : 3
