Question

plz explain me tomorrow is my paper

Answer 1

Find the total interest:

Interest = 5400 - 4500 = Rs 900

Find the interest for 1 year:

3 years = Rs 900

1 year = 900 ÷ 3 = Rs 300

Find the interest rate:

interest rate = interest/principle x 100

interest = 300/4500 x 100 = 20/3 = 6.67%

Answer: The interest rate is 6.67%

Answer 2

Given :

principal (P) = 4500

Amount (A)= 5400

Time (T)= 3 years

Finding Interest

Interest = Amount - principal

= 5400 - 4500 = 900

Interest ( I ) = 900

Finding Rate -

$rate \: = \dfrac{i \times 100}{p \times t}$

$rate = \dfrac{900 \times 100}{4500 \times 3}$

$= \dfrac{90000}{13500}$


= 6.66%

$\bold{Rate \: is \: 6.66 \%}$
