Elsa · Answer 1

Rule of 72, number of years taken to double the amount = 72/Rate of interest

Hence,

5=72 / Rate

Annual rate promised = 72/5 = 14.4%

It is a good deal if the opportunity cost is less than 14.4%

Let's assume it takes N number of years

400 * (1+0.144) ^N = 26,000

(1.144) ^N = 65

N lies between 31 and 32 years
