Question

simple interest on a certain sum 16/25 of the sum.find the rate percent and tne time if both are numerically equal​

Answer 1

Answer:

Rate = 8% and Time = 8 years

Step-by-step explanation:

Let sum = X.

Then S.I = 16x/25

Let rate = R% and Time = R years.

Therefore,  (x * R * R)/100 = 16x/25   =>  R = 40/5 = 8

∴ Rate = 8% and Time = 8 years.
