Question

At what rate percent per annum with rupees 4500 amount of to rupee 5715 in 3 year ​

Answer 1

Answer:

$Rate\:of \: interest (R)=9\%$

Step-by-step explanation:

Given Principal (P) = Rs4500

Amount (A)=Rs5715

Time(T)=3 years

Let Rate of interest = R,

Simple interest (I)=A-P

= Rs 5715 - Rs 4500

= Rs 1215

$R= \frac{100\times I}{PT}$

$=\frac{100\times 1215}{4500\times 3}\\=9\%$

Therefore,

$Rate\:of \: interest (R)=9\%$
