Answers
Answer:
It will take 10 years to triple the principle amount .
Step-by-step explanation : As in 1st condition :- i = p , so that p + 1 = 2p in 5 years . Therefore , ( p = p*t*r ) / 100 or , r = 100 / 5 or , 20 % Now in 2nd condition :- i = 2p , such that total amount = 3p r = same = 20 % Therefore t = 10 years .
