Question

calculates the amount 4000 at 9% per annum for 3 years​

Answer 1

Given: principal =4000

                     rate = 9%

                     time = 3 years

We will first find the interest

Simple interest = ( p × r × t)/100

                         = ( 4000 × 9 × 3)/100

                         = 1080

Now, we have to find the amount

So, amount = principal + interest

                  = 4000 + 1080

                 = 5080

Hence, the amount will be Rs. 5080

Answer 2

As per data given in the question ,

principle$=4000$

Rate of Interest=$9%$%$per annum$

Number of year$=3 years$

we have to find amount for $3$ years so

Rate of Interest$= 3 \times 9$$=27$%

for simple interest$=\frac{27}{100} \times4000=1,080$

and total amount$=4,000+1080=5,080$

Therefore, 5,080is required amount.
