- Let Ravi's income be Rs x. Then Shiv's income is Rs 2x.

- Ravi's expenditure is Rs y. So Shiv's expenditure is Rs 3y.

- Both save Rs 4000 each. So:

- For Ravi: x - y = 4000

- For Shiv: 2x - 3y = 4000

- Solve these equations:

- From Ravi: x - y = 4000 (1)

- From Shiv: 2x - 3y = 4000 (2)

- Multiply equation (1) by 2: 2x - 2y = 8000

- Subtract from (2): (2x - 3y) - (2x - 2y) = 4000 - 8000 ? -y = -4000 ? y = 4000

- Substitute y in (1): x - 4000 = 4000 ? x = 8000

- Shiv's income = 2x = 2 × 8000 = Rs 16,000

Option 1: Rs 16,000 is correct.
