Answer 2

Answer:

t =20 years

Step-by-step explanation:

Consider the provided information:

The amount invested is 2000.

• Double the amount means: 2000×2 = 4000

We had invested only 2000 and we are getting 4000. That means simple interest is 2000.

Now use the simple interest formula:

• S= p×r×t

100

Where, S is the simple interest, P is the principal amount, R is the rate and t is the time.

Substitute the respective values in the above formula.

• 2000 = 2000×5×T

100

• t = 100

5

• t = 20 years
