Question

A principal doubles in 5 years at a particular rate of simple interest. In how many years will the amount of the same principal at the same rate be three times the principal?​

Answer 1

Answer:

Time required is 20 years.

Step-by-step explanation:

Let the principal money be P.

Amount t=2P. Therefore interest =(2P-P) =P.

Time=5years.

Let rate of interest be Ready.

Therefore,

P = (PR * 5)

R=(1/5) =20%.

If the amount is = 5F .

Then interest = (5P-P) =4P.

Now,

4P =(Px0.2×T)

T=20 years.

Answer 2

Answer:

It will take 20 years to make the same principal with the same rate of interest becomes five times.

Hence, it will take 20 years to make the same principal with the same rate of interest becomes five times.
