A, B, and C all three invested in scheme at 20% SI for 2 years. A, B, and C entered in partnership with interest received from the scheme for 1 year, 8 months, and 4 months respectively. Find out the ratio of the profit shared by A, B, and
C. 

Interest received in scheme after two years = 1/5 × 2 × P  Interest received by A in scheme after two years = 1/5 × 2 × 18000 = Rs 7200  Interest received by B in scheme after two years =1/5 × 2 × 26000 = Rs 10400  Interest received by C in scheme after two years = 1/5 × 2 × 32000=  Rs 12800  A, B, and C entered in partnership for 12 months, 8 months, and 4 months  Ratio of the partnership = 7200:10400:12800 = 9:13:16  Ratio of time period = 12:8:4  Ratio of profit earned = (9×12):(13×8):(16×4) = 27:26:16
