a sum of-​

Answer 1

Answer:

The answer will be Rs 100/x.

Step-by-step explanation:

We have given;

               Rate in simple interest = x%;

               Time  = x years;

               Simple Interest = Rs. x

Formula for Simple Interest is;

                  S.I.(Simple Interest) = (Principle * rate * time) / 100;

   Now, put the values of respective variables in the formula;

                   x = (Principle * x * x)/100;

                   x = (Principle * x^2) / 100;

               100x = x^2 * Principle;

               Principle = 100x / x^2;

               Principle = 100/x;

Hence, the Principle amount will be Rs 100/x.

That's all.
