ArithmeticRatio, Proportion & Mixtures
The incomes of A and B are in the ratio 3 : 2 and their expenditures are in the ratio 5 : 3. If each saves Rs. 1,000, then B's income is
  1. a.Rs. 3,000.
  2. b.Rs. 4,000.
  3. c.Rs. 6,000.
  4. d.Rs. 800.

Answer: (B) Rs. 4,000.

Let incomes = 3x and 2x; expenditures = 5y and 3y. $3x - 5y = 1000$ and $2x - 3y = 1000$. Solving: $x = 2000$, so B's income = $2x = $ Rs. 4,000.
