Step-by-step explanation:

Let P = Rs. 100

A = Rs. 200

I= Rs. 200 - Rs. 100 = Rs. 100, T = 8 Years

R = (100 x 1)/(P x T) = (100 × 100)/(100 × 8) X = 100/8 = 25/2 %

Now again P = Rs. 100

A = Rs. 300

I= Rs. 300 - Rs. 100

= Rs. 200

R = 25/2%

T = (100 × 1)/(P x R) = (100 x 200)/(100 × (25/2))

(100 x 200 x 2)/(100 x 25) = 16 Years

So the given sum of money will become triple in 16 years.
