Step-by-step explanation:

Given: some of money doubles itself in 12(1/2) years.

To find : At what rate of simple interest will a some of money doubles itself in 12(1/2) years.

Solution: Simple interest formula is A= (p+rate)

Wher P= principle

R= rate of interest

T= time period

A= total return or principle plus interest earned during time period.

So, simple putting your inputs in the equation I.e.

A=> 2×principle

Time frame = 12(1/2) years.

We get,

=> 2p= p(1+25/2rate)

Concilling p as they are common, we get

=> 4= 2+25rate

=> rate= 2/25×100

=>. Rate= 8%
