Answer 2

Answer:

Hey friend,

Here is the answer you are searching for,

Let the Principle be x,

According to the question,

Amount = 2x

=>Simple Interest = 2x - x = x

According to the formula,

Time = Simple Interest × 100/Principle × Rate

Therefore,

Time = x × 100/x × 20 = 100/20 = 5 years.

HOPE IT HELPS YOU.
