​

Answer 1

Answer:

Answer. Therefore Amount will triple itself in 16 years and 8 months.

Answer 2

Step-by-step explanation:

Let the sum of money that's principal be x.

Time=8 years

Amount after 8 years becomes double=2x

Therefore,

Simple interest=Amount -principal=2x−x=x

Rate per annum =P×TS.I×100=x×8x×100=8100=225=12.5%

Then,

We get interest of 8years is 12.5%
