Answer 1

Answer:

The question is incomplete. Here is the complete question:

The SI on a sum of money is 1/9 of the principle, and the number of years is equal to the rate %. p.a. Find the rate %.

Answer:

Let the principal be P.

Rate of interest be R%

According to the question, Time = R

Simple interest = P/9.

SI = (P × T × R) / 100

⇒ P/9= (P × R × R) / 100

⇒ P/9= (P × R2) / 100

⇒ 1/9= (R2) / 100

⇒ R2 = 100 / 9

⇒ R = 10/3

Therefore, rate of interest is 10/3 % or 3 1/3 %.
