Question

Find the simple interest on ₹ 7850 at 7% per annum for 3 years. Also find the
amount.

Answer 1

Answer:

Interest = ₹1648.5

Total amount = 7850+1648.5

= ₹9498.5

Step-by-step explanation:

Given,

Principal amount (P) = 7850

rate of interest (R) = 7%

Time (T) = 3yr

Simple interest = (PTR)/100

on substituting P,T,R values in above eqn

I = (7850×3×7)/100

The interest is ₹1648

Answer 2

Answer:

Simple interest is Rs. $1648.5$.    

Amount is Rs. $9498.5$

Step-by-step explanation:

Given : Principle (P)= Rs. $7850$

          Rate of interest (R) = $7$%

          Time period (P) = $3$ years

To find : Simple interest =?

Solution :

• It is given that Principle (P)= Rs. $7850$

          Rate of interest (R) = $7$%

          Time period (P) = $3$ years

• We have to find the simple interest.
• To find the simple interest, formula is given by

     Simple interest = $\frac{P*R*t}{100}$

                           = $\frac{7850*7*3}{100}$        

                           = $\frac{164850}{100}$        

                           = Rs. $1648.5$      

• ∴ Simple interest is Rs. $1648.5$.      
• Now,

    Amount (A) = Principle + Simple Interest

                      = $7850+1648.5$  

                      = Rs. $9498.5$  

• ∴ Simple interest is Rs. $1648.5$.    
• Amount is Rs. $9498.5$
