Arjun started a business with the investment of Rs. 8000. After 4 months, Bhanu joins him with the capital of Rs. 10000. After 8 months of starting the business, Chandan also joins him with the capital of Rs. 15000. Find the share of Chandan in the profit of Rs. 118000 after 1 year ?

Calculate each partner's capital contribution multiplied by their investment duration. Arjun: 8000 × 12 = 96000. Bhanu: 10000 × 8 = 80000. Chandan: 15000 × 4 = 60000. Total ratio = 96000:80000:60000 = 24:20:15. Chandan's share = (15/59) × 118000 = 30000. The profit is divided in proportion to both capital amount and time period invested.
