Question

find the simple interest of when p=rs.12000'R=3and T =4Years

pls help me guys​

Answer 1

Simple Interest

Simple Interest is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

The basic formula to calculate Simple Interest is as follows:

$\implies \boxed{\bf{SI = \dfrac{P \times R \times T}{100}}}$

Where, SI denotes Simple Interest, P denotes Principal Amount, R denotes Rate of Interest and T denotes Time Period.

According to the given, we've been given that,

• Principal, P = Rs. 12000
• Rate, R = 3%
• Time, T = 4 years

By substituting all the given values in the formula, we get:

$\implies SI = \dfrac{120\cancel{00} \times 3 \times 4}{1\cancel{00}} \\ \\ \implies SI = 120 \times 3 \times 4 \\ \\ \implies SI = 360 \times 4 \\ \\ \implies \boxed{\bf{SI = 1440}}$

Hence, the simple interest is Rs. 1440.

IMPORTANT FORMULAE

Simple interest SI on a certain sum of money of Rs P invested at the rate of R% per annum for T years is given by,

$\implies \boxed{\rm{SI = \dfrac{P \times R \times T}{100}}}$

Simple interest SI on a certain sum of money of Rs P invested at the rate of R% per month for n months is given by,

$\implies \boxed{\rm{SI = \dfrac{P \times R \times n}{12 \times 100}}}$

Simple interest SI on a certain sum of money of Rs P invested at the rate of R% per day (non-leap year) for d days is given by,

$\implies \boxed{\rm{SI = \dfrac{P \times R \times d}{365 \times 100}}}$
