Please mark the answer as "The Brainliest answer" if it helps

Step-by-step explanation:

let say bina income = B

Avin income = (5/8)B = 5B/8

Let say bina expense = x

Avin expenses = x/2

Avin saving = 5B/8 - x/2

Avian saving = 40% of avin income

5B/8  - x/2  = (40/100) * (5B/8)

5B - 4x = 2B

3B = 4x

x = 3B/4

Bina Expense = 3B/4

Bina Saving = B - 3B/4 = B/4

Bina Saving % = ((B/4)/B) * 100 = 25 %
