Question

5000 രൂപക്ക് 2 വർഷത്തേക്ക് 800 രൂപ സാധാരണ പലിശ കിട്ടുമെങ്കിൽ പലിശ നിരക്ക് എത്ര​

Answer 1

Given:

Rs.5000 gets the normal interest of Rs.800 for 2 years

To find:

The rate of interest

Solution:

We will use the following formula of simple interest to solve the given-problem:

$\bigstar\boxed{\bold{Simple\: Interest = \frac{Principal\times Rate\times Time}{100} }}\bigstar$

Here we have,

Principal, P = Rs. 5000

Time, T = 2 years

Simple interest, S.I. = Rs. 800

Let "R" represent the rate of interest.

Now, substituting the given values in the formula of simple interest, we get

$800 = \frac{5000\:\times\: R\:\times\: 2}{100}$

$\implies 800 \times 100 = 5000\:\times\: R\:\times\: 2$

$\implies 80000 = 10000\:\times\: R$

$\implies R = \frac{80000}{10000}$

$\implies \bold{R = 8\%}$

Thus, if Rs.5000 gets the normal interest of Rs.800 for 2 years then the interest rate is 8% p.a.
