    1. Principal: The money borrowed or lent out for a certain period is called the
    principal or the sum.
    2. Interest: Extra money paid for using other's money is called interest.
    3. Simple Interest (S.I.) : If the interest on a sum borrowed for a certain period is reckoned uniformly, then it is called simple interest.
    Let Principal = P, Rate = R% per annum (p.a.) and Time = T years. Then,
    (i) S.I. = (P*R*T )/100
    (ii)P=(100*S.I)/(R*T) ;R=(100*S.I)/(P*T) and T=(100*S.I)/(P*R)
