Two partners, A and B, start a business together. A invests Rs.16,000 for 8 months, while B participates for 4 months. If B's share of the total profit is 2/7, what amount did B invest?
Explanation
The ratio of investments multiplied by time for A and B is (16000 × 8) : (x × 4) = 5 : 2. Solving for x gives x = 12800. Therefore, B invested Rs.12,800.
