ArithmeticRatio, Proportion & Mixtures
At the beginning of a year A and B jointly started a business by investing ₹ 17,000 and ₹ 20,000 respectively. After four months, A made a further investment of ₹ 4,000 in this business. If the profit was ₹ 9,520 at the end of the year, find the share of profit of A.
- a.₹ 4,800
- b.₹ 4,620
- c.₹ 4,720
- d.₹ 4,820
Answer: (C) ₹ 4,720
A's capital-months = 17000 × 4 + 21000 × 8 = 236000 and B's = 20000 × 12 = 240000, so the ratio is 59 : 60. A's share = $\frac{59}{119} \times 9520$ = ₹ 4,720. ₹ 4,800 is B's share.
