Question

A sum of money becomes triple of itself in 8 yr
at SI. In twelve years, it will become how many
times of itself at the same rate?
(a) 6 times
(b) 4 times
(c) 5 times
(d) None of these
​

Answer 1

Answer:

I think the answer should be none of these

Answer 2

4 times

Step-by-step explanation:

P : A : I

1 : 3 : 2

interest of 8yrs = 3-1 = = 2

interest of 12 years = 12 ×2/8 = 3

so new Amount = P + Interest

= 1 + 3 = 4 (times of principal )

option(b) is correct
