In how much time would the simple interest on a certain sum be 0.125 times the principal at 10% per annum?
1 1/4 years
1 3/4 years
2 1/4 years
2 3/4 years
Explanation:
Let sum = x. Then, S.I. = 0.125x = 1/8 x, R = 10%
Time = (100 $\times$ x) / (x $\times$ 8 $\times$ 10) = 5/4 = 1 1/4 years.
Let sum = x. Then, S.I. = 0.125x = 1/8 x, R = 10%
Time = (100 $\times$ x) / (x $\times$ 8 $\times$ 10) = 5/4 = 1 1/4 years.
