Simple Interest on 1st Part at 4% per annum for 3 years, Simple Interest on 2nd part at 6% per annum for 4 years and Simple Interest on 3rd Part at 8% per annum for 5 years are equal. Find each part.Solution
Let the Principal for 1st part be A Principal for 2nd part be B Principal for 3rd part be C According to the question, (A ×4 ×3)/100= (B ×6 ×4)/100= (C ×8×5)/100 12A = 24B = 40C (LCM of 12, 24 and 40) = 120 12A /120= 24B/120 = 40C/120 A/10 = B/5 = C/3 So A:B:C = 10 : 5 : 3 A =10/18×25200= 14000, B ==5/18×25200= 7000 and C = =3/18×25200=4200
