Question

simple intrest on a sum is 16/100 of the sum. find the rate percent and the time, if both are numericaly equal​

Answer 1

Answer:

The rate percent is 4 and the time is 4 years

Step-by-step explanation:

Given : Simple interest = I = 16/100 of the sum = P x 16/100

            Rate percent = time, R= T

            R =? and T=?

Solution : simple interest I = PTR/100

Substituting the values given, we get

                                     P x  16/100 = P x T x T/100

                                     T² = P/P x 16 x 100/100

                                     T² = 16

                                      T = 4 years

Since T=R, then R = 4 %
