Hi, Here A=P +SISo 5070=P+ Prt100=P+ P×r×3100×2 Since 18 months = 3/2 years5610 = P+ P×r×9100×2Subtracting we get 540=6Pr200Pr= 18000Putting this in first equation, 5070= P+54000200P = 5070-270= 4800So r = 180004800= 3
75 % Now you have Principal as well as rate so find the amount using formula A =P+Prt100 where t = 5 Regards
