Answer:
100/3
Step-by-step explanation:
Sum of Amount = P
it becomes 5 Times to Final AMount = 5P
Simple interest = 5P -P = 4P
Simple interest = (Principle * Rate of interest * Time)/100
4P = P * 12 * T /100
400 = 12T
T = 400/12
T = 100/3

It is given that the sum of the amount= P
the sum of the amount becomes 5 times to the final amount=5P
Now, the simple interest (SI)=4P (5P-P)
We know that Simple Interest (SI)=principal (P)×rate of interest (R)×time (T)/100
4P=P×12×T/100
4P×100=12PT
400P=12PT
400P/12P=T
100/3=T
the sum of the amount becomes 5 times to the final amount=5P
Now, the simple interest (SI)=4P (5P-P)
We know that Simple Interest (SI)=principal (P)×rate of interest (R)×time (T)/100
4P=P×12×T/100
4P×100=12PT
400P=12PT
400P/12P=T
100/3=T
