The incomes of A and B are in the ratio of 3:2 and their expenses are in the ratio of 5:3. If each of them saves Rs.3000, then A's income (in Rs.) is

A's income is Rs. 18000.

Let incomes be 3x and 2x, expenses 5y and 3y, each saving 3000.

So 3x - 5y = 3000 and 2x - 3y = 3000.

Solving these together gives x = 6000.

A's income = 3x = 3 x 6000 = 18000.
