Answer:
It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
Step-by-step explanation:
Use the formula for continuous compounding

where r stands for the (annual) interest rate, t for time in years, P for the initial principal (investment) and X is the amount after t years.
(this formula can be beautifully derived from just basic considerations, btw)
We are given t=5, and percent increase on the initial P, so we can solve for r

It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
Let x= 2.3181818...
then
10x=23.181818... and
1,000x=2,318.1818...
1,000x-10x=2,318.1818...-23.181818...
990x = 2,318 - 23
990x = 2295
x=2295/990
dividing by 5 both numerator and denominator:
x= 459/198
now, x= 198 + 198+ 63
so

Step-by-step explanation:
A scalene right triangle comprised of integers must have the same ration as 5:4:3, and 5:6:8 is not it.
