## Simple Interest Math pdf Notes

Students, to solve the questions related to simple interest, you need to remember some important things which are as follows-

• Principal : – It is the money which a person takes in loan from any other person or bank or other financial institutions. Its sign is P.
• Time : – The money taken in the form of loan is day after a certain period, this period is called time, the sign is t.
• Rate: – Every loan is given at a fixed rate, which is usually expressed in percentage. The sign is r.
• Interest :- The borrower pays some more amount in addition to the principal after the end of the time, this extra amount is called interest. The sign is I.
• Amount :- It is the entire amount which is to be returned by the borrower, it includes both principal and interest.

## something to note

• Simple interest has a proportional relationship with P, r and t.
• When only P is changed by n or by x% (increasing incidence) then SI also changes by the same ratio. For example, if P is doubled, then SI will also be doubled. If it is increased by 40% then SI will also increase by 40% if r and t are constant.
• When P is multiplied by m times, r is multiplied by n and t is increased or decreased by P times, then SI will increase or decrease by (m × n × P) multiplication respectively.
