Tanu started a business by investing Rs.2100 and after 2 months Ravi joined by investing Rs.1500. At the end of 4 months from the start of the business, Rohit joined with an investment of Rs.3000. At the end of 10 months from the start of the business, Tanu added an additional amount of Rs.900. If Tanu's share in the annual profit was Rs.810, what was the total annual profit?
Ratio of profit of Tanu, Ravi and Rohit
= 2100 × 10 + 3000 × 2 : 1500 ×10 : 3000 × 8
= 21000 + 6000 : 15000 : 24000
= 27000 : 15000 : 24000
= 27 : 15 : 24 = 9 : 5 : 8
Total profit = 9x + 5x + 8x = 22x
∴ Tanu's share in profit is 810
∴ 9x = 810
x = 90
Total profit = 90 × 22 = 1980
