Question

if the simple interest on certain amount of money for 3 years is 3/10 of the sum,then find the rate of interest per annum​

Answer 1

Answer

Rate%=10%

Step-by-step explanation:

given: time =3 years

S.I=three ten of the principal

To find: Rate %

let principal be x

S.I=3/10 of x

As we know that

S.I=p×r×T/100

3/10 x=x×r×t/100

3x/10=3x/100

3T l0× 100/3=x

Therefore x=10%
