What is Principal ?

When money borrow for a certain time period called Principal or Sum.


What is Amount ?

The Addition of Simple Interest and Principal is called the Amount.
A = S.I + P ( Principal ).
S.I = A ( Amount ) – P ( Principal ).

 


What is Per annual means ?

Per annual means For a year.

  • P =Principal
    R = Rate of per annual
    T = Number of years

When we Add Simple Interest into Principal. It becomes into Amount.

 


  • Formulas Need to Remember

    S.I =( P X R X T / 100 )
    Here, P =Principal.
    R = Rate per annual.
    T = Number of years.

 


Formula:

In case S.I ( Simple Interest ), T ( Number of years ) and R (Rate per annul ) are given in Question then we can easily find the Principal or Sum.
P = ( S.I X 100 / R X T ).

 

 

Formula:
In case S.I ( Simple Interest ), T ( Number of years ) and P (Principal ) are given in question then we can easily find the R (Rate per annual ).
R = ( S.I X 100 / P X T ).

 

 

Example 1:
Find the simple interest on Rs 500 for 5 years at 5 per cent ?
Answer :
SI = 500 x 5 x 5 / 100
Simple interest in 5 years is Rs 125.

 

 

Example 2: In What time Rs. 5000 amounts to Rs. 6000 at 5% P.A at simple interest ?
Answer : 1000 = 5000 x 5 x t / 100
t = 4 years.

    With a given rate of simple interest the ratio of principal and amount for a certain period of time is 4:5.after 3yrs with tthe same rate of interest the ratio of the principal and amount becomes 5:7.The rate of interest per annum is ???
    Solve it

    • sujit swain says:

      let take p=100,
      then, amount(a)=125(since ratio is 4:5)
      hence,SI=125-100=25.
      then after 3 yr the ratio will b 5:7
      soo p=100,amount=140

      now in 3 yr SI=140-125=15
      i.e 3r=15
      r=5% (ans)
