Question

in how much time the simple intrest of a certain sum 0.125 times the principle at 10% per annum​

Answer 1

Answer:

Step-by-step explanation:

Let the principal/sum be x.

Given SI = 0.125 = 1/8 x, R = 10%.  

We know that Time = (100 * SI)/(P*R)

                                = 100 * x/x * 8 * 10

                                = 5/4 (or) 1 1/4 years.
