1.	EXERCISE26.1amount doubles, in 5 years by the simple interest. How many years areAned for the same amount with same rate of interest to get converted to fiveimes the original amountl) 12 years (2) 20 years (3) 25 years (4) 10 years2
Answer» According to the question, I = P = (Pr5)/100=> 100= r5=> r= 20% For amount to become 5 times, I = 5P-P = 4PTherefore, 4P = (Prt)/100=> 4= (20t)/100=> t = 20 years. thanks

Answer»

According to the question, I = P = (P*r*5)/100=> 100= r*5=> r= 20%

For amount to become 5 times, I = 5P-P = 4PTherefore, 4P = (P*r*t)/100=> 4= (20*t)/100=> t = 20 years.
