Answer 1

Answer:

5:27

Step-by-step explanation:

let income of A be A,B be B and

expense of A be A1, B be B1

Income

A=70%B

=0.7B

Expenses

B1=A1×(1-20%)=A1(1-.2)

=0.8A1

A1=60%of B income

=0.6B

savings of A = A-A1

=0.7B-0.6B=0.1B

B1=0.8A1=0.8×0.6B=0.48B

savings of B =B -B1

=B-0.48B=0.54B

savings of A:B= 0.1B:0.54B=10:54=5:27
