Answer 1

Answer:

simple interest = P×R×T

Step-by-step explanation:

Simple interest = 2800×5×2

28000

Answer 2

$\sim \underline{ \bf{Question}}$

On the above Simple Interest based question we gets the following data :-

• Principal = Rs. 2800
• Rate of interest = 5%
• Number of years = 2

To Find

1. Simple Interest.
2. Amount.

Answer

$\twoheadrightarrow \sf \: Simple \: Interest = \pink{ \bf ₹ 280}$

$\twoheadrightarrow\sf \: Amount = \red{ \bf₹ 3080}$

Solution

Here , in the above question we are provided with Principal , rate of Interest as well as time what we need to calculate is Simple Interest & Amount . We know that the formula for the Calculation of Simple Interest is P × R × T since R is in terms of % so it should be written as R/ 100 .

Therefore, the formula for Simple Interest is

$\boxed{ \bf S.I = \sf\dfrac{P × R × T }{100} }$

On Implementating , the above values we get ,

$\sf S.I \: = \dfrac{ 28 \cancel{00} \times 5 \times 2} { 1\cancel{00}} = \dfrac{28 \times 10}{1} \\ \colorbox{cyan}{\tt S.I = ₹ 280}$

Now , in order to calculate the Amount we have the following authorized formula :-

Amount = Principal + Simple Interest

$\sf \: Amount =₹( 2800 + 280) = \colorbox{cyan}{₹ 3080}$

Conclusion

1. Simple Interest = ₹ 280
2. Amount = ₹ 3080

$\rule{200pts}{1pts}$

General Concepts :-

1. To calculate the Interest, the formula becomes : I = ( P × T × R ) /100 .
2. To calculate the Principal Amount, the formula is : P = ( I × 100 ) / R × T.
3. To find the rate of interest, the formula will be : R = (I × 100)/ PT.
4. To get the time, formula is : T = (I × 100) / PR .
5. After the calculation for S.I , the principal has to be added to it to get the total amount that the borrower has to give or the lender will collect. This is called total amount and its formula is given as. A = P + SI .
6. Simple interest is the total amount paid to the borrower for using the borrowed money for a fixed period.
7. The Rate in S . I refers to Rate of Interest of Loans at which you have lent money to someone or invested your money in any investment scheme.
