Rohith started a business by investing Rs. 3600. After somedays, Puneeth joined him by investing Rs. 2400. At the end of one year, the profit was divided in the ratio 2 : 1. After how many months did Puneeth join the business?
Correct Answer: 3 months
Explanation:
Ratio of profit of Rohith and Puneeth = 3600 x 12 : 2400 x P
= 3600 x 12/2400P = 2/1
=> P = 9
So, Puneeth joined the business after (12 - P) = 12 - 9 = 3 months.
