A Correct answer
Explanation

The ratio of incomes is 2:3. If 2 parts = 9000, then 1 part = 4500. Vimala's income is 3 parts = 3 * 4500 = 13500.

AI explanation

The ratio of incomes means that for every 2 parts Kamala earns, Vimala earns 3 parts. We are given that Kamala's income of Rs. 9,000 represents these 2 parts. To find the value of one part, divide 9000 by 2 to get Rs. 4,500. Vimala's income is 3 parts, so multiplying 3 by Rs. 4,500 gives Rs. 13,500.
