- Let's denote the incomes as 4x and 5x for the two persons, respectively, based on the ratio 4:5.

- Their expenditures can be denoted as 7y and 9y based on the ratio 7:9.

- Each person saves Rs50 per month, so their savings equations are:

- 4x - 7y = 50

- 5x - 9y = 50

- Solving these equations, we find x = 100 and y = 50.

- Option 1: Rs400; Rs500

- Option 2: Rs700; Rs900

- Option 3: Rs900; Rs500
