A started a business by investing ₹76000. After few months B joined him and invested ₹57,000. At the end of the year, the total profit was divided between A and B in the ratio 2 : 1. For how many months B remained in the business?

8

Let A invested Rs.76000 for 12 months and B invested Rs.57000 for x months

Then (7600×12)/(5700×x) = 2/1

⇒x = (76×12)/(57×2) = x=8
