Answer 2

A sum of money triple itself at 16% p.a. at simple interest in 12.5 years

Step-by-step explanation:

Let the sum of money be x

Amount = 3x

Simple interest = Amount - Principal = 3x-x=2x

Rate of interest = 16%

$Si = \frac{P \times T \times R}{100}$

$2x=\frac{x \times T \times 16}{100}$

$\frac{200}{16}=T$

12.5 = T

Hence A sum of money triple itself at 16% p.a. at simple interest in 12.5 years
