Question

The simple interest on a sum of money is 4/9 of the principal and the number of years is equal to the rate percent per annum . What is the rate percent per annum ?​

Answer 1

Answer:

Let the principal be P.

Rate of interest be R%

According to the question, Time=R

Simple interest =94P.

SI=100(PTR)

⇒94P=100(PTR)

⇒94P=100(P×R×R)

⇒94P=100(P×R2)

⇒94=100R2

⇒R2=100×94

⇒R=10×32=320

Therefore, rate of interest is 320% or  632%.
