Simple interest on a certain sum at a certain annual rate of interest is 1/4 of the sum.
Simple interest on a certain sum at a certain annual rate of interest is 1/4 of the sum. If the numbers representing rate percent is 5time of years , then the Time is:
Answer/Solution
2 1/2 years.
Steps/Work
Explanation :
Let sum = x. Then, S.I. = x/4
Let Time =N and R = 4 N.
[x * N * 4N / 100] = x / 4? N^2 = 25/4
N = 5/2 = 2 1/2 years.
Hence,n = 2 1/2 years.
