Question

IP = 800 rupees. R5% and T-2 years, then End simple interest​

Answer 1

Answer:

formula A= P(1+rt)

Step-by-step explanation:

A = final amount

P = initial principal balance

R = annual interest

T = time in years

step :- A =

P =

R = 5% PER SEN

T = 2 years

step 2 : SI = P X R X T

P PRINCIPAL

R RATE

T TIME

Answer 2

Given: Rs. 800 is invested at 5% per annum for 2 years

To find: The simple interest on the money

Solution: The money that is invested is called the principal. It is the sum on which interest is calculated.

Let the principal be denoted by p, rate by r and time by t.

p = Rs. 800

r = 5%

t = 2 years

The formula for simple interest is

= p × r × t / 100

= 800 × 5 × 2 / 100

= 8000/100

= 80

Therefore, the simple interest on the principal at 5% per annum for 2 years is Rs. 80.
