- Let, Principal amount be P.Rate of interest be R per annum. Time of investment is
(T)=12 years.Sum of the money becomes three times in 12 years.
⇒A=3P.⇒A=P+(P×T×R100)⇒3P=P(1+T×R100)⇒3=1+12×R100⇒3−1=12R100⇒2=3R25
⇒50=3R⇒503=RNow, we need to find the number of years
T such that, Sum of the money becomes five times.⇒5P=P(1+T×R100)⇒5=1+T×503×100⇒5−1=T×13×2
