dont worry

Explanation:

Let x % be the simple interest per annum on Principal amount(P) you deposited.

After 1 year your money will become P + x% P.

After 2 year your money will become P + x%P + x% P.

Similarly, After 6 years your money will become P + 6 (x% P).

Now According to Question, this amount after 6 years is 2 times the amount you deposited i.e P.

Mathematically it can be expressed as,

2P = P + 6 (x% P) ……………(i)

From here, x = 100/6.
