### What is Principal?

What is Amount?
The Addition of Simple Interest and Principal is called Amount.
Amount (A) = Simple Interest (SI) + Principal (P).
Simple Interest (SI) = Amount (A) – Principal (P).

### What is Per annual means?

Per annual means for a year.

Few general terms of Interest

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

### Formulas Need to Remember

Formula #1
SI = ( P x T x R / 100 )
Here, P = Principal
R = Rate per annual
T = Number of years

Formula #2
In case Simple Interest, Number of years and Rate per annul are given in question, then we can easily find the Principal or Sum.

P = ( SI x 100 / R x T )

Formula #3
In case Simple Interest, Number of years and Principal are given in question, then we can easily find the Rate per annual.

R = ( SI x 100 / P x T )

### Example #1

Find the simple interest of Rs.500/- for 5 years at 5% per annum.

1. Rs.75/-
2. Rs.100/-
3. Rs.125/-
4. Rs.150/-

### Example #2

In what time Rs.5000/- amounts to Rs.6000/- at 5% per annum at simple interest?

1. 2 Years
2. 4 Years
3. 5 Years
4. 7 Years

Show Answer Show How to Solve Open Rough Workspace

How to Solve
1000 = 5000 x 5 x T / 100
T = 4

So, in 4 years Rs.5000/- will increase to Rs.6000/-.

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)
