Question

In what time will a sum of money doubles itself at 5%interest per annum​​

Answer 1

Answer:

Here is your answer

Explanation:

I will solve this question on the basis of simple interest.

Assume,

P=sum of money

r=5%

time=?

the total interest will be equal to P when the sum gets double.

so the equation will be

(p×5×time)/100=p

( 5×time)/100= 1 [ Both side p got cut]

time=20 year

☆ It will require 20 years to make the sum double at 5% interest
