Download Simple interest - important formula and question

Every aspirant who understands percentages and the principles of arithmetic and geometric progressions will be able to handle problems of simple interest (SI) and compound interest (CI) easily. In SSC, CAT, XAT or other exams, the problems on simple and compound interest are asked as a part of checking your calculation power only. Let me start this lesson with a simple problem:   


Method and formula
  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 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). Simple Intereest =P x R x T
    (ii). P =100 x S.I.; R =100 x S.I.and T =100 x S.I..
    R x TP x TP x R
