Answer 1

I hope this will help you

Answer 2

Answer:

The simple interest is 882Rs and the amount is 5082Rs.

Step-by-step explanation:

Given: Principal = 4200 Rs,rate of interest (p.c.p.a.)=7%, time=3 years

We have to find interest and Amount.

• As we know, the simple Interest of an amount is calculated by multiplying the interest rate by the principal amount and the time period.  
• The formula is used to calculate the simple interest is:

         $S I=\frac{P R T}{100}$

Where,

$P= Principal \ Amount\\T= Time\ in \ Years\\R= Rate \ of\ Interest\ per\ Annum.$

We are solving in the following way:

We have,

Principal = 4200 Rs, rate of interest (p.c.p.a.) = 7%, time = 3 years

Now,

The simple interst will be:

$\begin{array}{l}S I=\frac{P R T}{100} \\\\S I=\frac{4200 \times 7 \times 3}{100} \\\\S I=\frac{88200}{100} \\\\S I=882\end{array}$

Hence, the simple interest will be 882Rs.

As we know the amount is calculated by:

Amount = Principal + Simple interest

$Amount=4200+882\\Amount=5082$

Hence, the amount will be 5082Rs.

NOTE:

Q. Principal =4200 Rs, rate of interest (p.c.p.a.)=7%, time = 3 years, then what is interest and the amount?
