Question

At what annual rate of interest will the simple interest be equal to half of the principal in 5 years?​

Answer 1

Answer:

10%

Step-by-step explanation:

let principle is X,

simple interest = X/2

simple interest = principle × rate × time /100

X/2 = X × Rate × 5 / 100

1/2 = Rate × 1 / 20

Rate = 10%
