Explanation:

Let’s break it down:

- Let Dinesh’s income = 17x, expenditure = 14x

- Savings = Income - Expenditure = 17x - 14x = 3x = Rs 1200

- So, x = 1200/3 = 400

- Income = 17x = 17×400 = Rs 6,800

- Expenditure = 14x = 14×400 = Rs 5,600

After change:

- New income = 6,800 + 10,000 = Rs 16,800

- New expenditure = 5,600 - 2,000 = Rs 3,600

New ratio = 16,800 : 3,600 = 168:36 = 14:3 (divide both by 1,200), but this does not match any options.

Let’s double-check:

- 16,800 / 3,600 = 168/36 = 14/3

Let’s check the given ratios with the calculated amounts:

- Option 1: 13:8 ? 16,800/3,600 = 4.67 13/8=1.625 Not Matching

- Option 2: 13:9 ? 16,800/3,600 = 4.67 13/9=1.444 Not Matching

- Option 3: 11:9 ? 16,800/3,600 = 4.67 11/9=1.222 Not Matching

- Option 4: 11:7 ? 16,800/3,600 = 4.67 11/7=1.571 Not Matching

It seems none exactly match, but as per calculations, the exact ratio is 14:3.

So,
