SIMPLE INTEREST 1

Rayan deposited the amount of 8,000/= in a bank for 5 years and got a profit of 1200/=. Find the interest rate?

Solution

I = 1200/=, P = 8,000/=, T = 5 years, R = ?

I = PRT

100

1200 = 8,000 x R x 5

100

1200 = 8,000 x R x 5

100

1200 = 80 x R x 5

1200 = 400R

³~~1200~~ = ~~400~~R

~~400~~ ~~400~~

Hence the interest rate was 3%
