Simple Interest Suppose, principal = . Rate of interest = R% and time = I So () Simple Interest (S.I.) = Principal × Interest Rate x Time PRT 100 100 100x (S.I.) 100 x simple interest (2) Principal (P) RxT Rate of interest x time 100 × (S.L.) 100) × simple interest (3) Rate of Interest (R) PXT Capital x time
