- Simple interest on a certain sum is 16/25 of the sum.
Question 1:
Simple interest on a certain sum is 16/25 of the sum. Find the rate percent and time, If both are numerically equal. A. Rate = 7% and Time = 7 years.
B. Rate = 8% and Time = 8 years.
Feedback 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
Therefore, Rate = 8% and Time = 8 years.
Let rate = R% and Time = R years.
Therefore, (x * R * R)/100 = 16x/25 => R = 40/5 = 8
Therefore, Rate = 8% and Time = 8 years.
C. Rate = 6% and Time = 6 years.
D. Rate = 5% and Time = 5 years.
