Answer:
Let principal amount, P = 100
Then, Simple Interest, SI = 200
Rate, R = 15%
Time, T = ?
Now,
SI = (P×T×R)÷100
200 = (100×T×15)÷100
T = 13.33 Years
E
Explanation:
Read on.
There is a sweet little relation that will give instantaneous answer :
(n - 1) x 100 = rt
In the given problem n = 3 & r = 15
Plugging values, (3 - 1) x 100 = 15 x t
=> t = 200/15 = 13 1/3 years.
