Question

please help me out ​

Answer 1

Step-by-step explanation:

Let Income of A = 2x

Income of B = 3x

Similarly Let expenditure of A = y

Expenditure of B = 2y

Now 90℅ of B expenditure = Income of A

j.e 0.9 × 2y = 2x i.e 1.8y = 2x …(1)

We know Saving = Income - Expenditure

Saving for A = 2x - y

Saving for B = 3x - 2y

Ratio of saving = (2x - y) : (3x - 2y)

Using (1) = (1.8y - y) : (2.7y - 2y) = 0.8y : 0.7y = 8 : 7

Hence Answer = 8 : 7
