A, B and C enter into partnership. A invests some money at the beginning, B invests double the amount after 6 months, and C invests thrice the amount after 8 months. If the annual gain be Rs.18000. A's share is?
Correct answer: C. Rs.6000
- A. Rs.7500
- B. Rs.7200
- C. Rs.6000
- D. Rs.5750
Explanation
Let A's capital be Rs.x. A contributes Rs.x x 12 months = Rs.12x-months, B contributes Rs.2x x 6 months = Rs.12x-months, and C contributes Rs.3x x 4 months = Rs.12x-months, so the profit is divided equally. A therefore receives Rs.18000 x 1/3 = Rs.6000. The likely mistake is option a, Rs.7500, which assigns A more than one-third without recognising that all three capital-time contributions are equal.
