Question

At what rate percent p.a. will the sum of money triples itself in 25 years?​

Answer 1

Step-by-step explanation:

If it is simple interest, use this relation to get instantaneous answer :

(n - 1) x 100 = rt

In the given problem n = 3 & t = 25

Plugging values, (3 - 1) x 100 = r x 25

=> r = 8%

If it is compound interest, use the relation ;

A = P(1 + r/100)^10

Since here A = 3P,

3P = P(1 + r/100)^25

r = (3^(1/25) - 1) x 100

= (1.045 - 1) x 100

= 4.5%
