Sarita started a business investing Rs 50,000. After six months Abhishek joined her with Rs 75,000. After another six months Nisha also joined them with Rs 1.25 lakh. Find the profit earned at the end of 2 years from when Sarika started the business if Nisha got Rs.12300 As her profit share?

Sarita invested Rs. 50,000 for 24 months, Abhishek invested Rs. 75,000 for 18 months, Nisha invested Rs. 1,25,000 for 12 months. Profit ratio = 50000×24 : 75000×18 : 125000×12 = 12,00,000 : 13,50,000 : 15,00,000 = 24 : 27 : 30 = 8 : 9 : 10. Nisha's share = (10/27) × Total Profit = 12300. Total Profit = 12300 × 27/10 = Rs. 33,210. Option C matches this calculation.
