A person spends 70% of his income in a month. In the next month, if his income increases by 40% and his expenditure increases by 30%, then his savings increase by ₹1,216. What is the person's original income?

  1. A. ₹8,960
  2. B. ₹2,482
  3. C. ₹3,475
  4. D. ₹6,400 ✓

Correct Answer: D. ₹6,400

Explanation

Let original income = 100x. Savings = 30x. New income = 140x, New expenditure = 70x \times 1.3 = 91x. New savings = 140x - 91x = 49x. Increase in savings = 19x = 1216 \Rightarrow x = 64. Original income = 100 \times 64 = 6400.
