SIMPLE INTEREST 1

Rayan deposited the amount of 8,000/= in a bank for 7 years and got a profit of 2800/=. Find the interest rate?

Solution

I = 2800/=, P = 8,000/=, T = 7 years, R = ?

I = PRT

100

2800 = 8,000 x R x 7

100

2800 = 8,000 x R x 7

100

2800 = 80 x R x 7

2800 = 560R

⁵~~2800~~ = ~~560~~R

~~560~~ ~~560~~

Hence the interest rate was Tsh 5%
