Question

in how much time will a sum of money double itself at 12 percent per annum simple interest

Answer 1

Answer:

9 years

Step-by-step explanation:

Let's assume you start off with ₹x

Then you will get ₹$\frac{12}{100}$x  every year

that means, you will get a little less than double money in 8 years and some more in 9 years

Answer 2

Answer:

We know that SI = PRT/100

We know that SI = A - P.

A - P = PRT/100

2400 - 1200 = 1200 * 8 * T/100

1200 = 96T

T = 1200/96

 = 12.5 years.
