What will be Time Required ? If
Answer: (2) 16 years
Rate = 6.25 %,
Let the principal be Rs. X ,
Then, the amount = 2 X Simple Interest = 2 X- X = X
Simple Interest = P x R x T/100
Where, P = principal , R = rate, & T = time.
Then, X = X x 25 x T /100 x 4
1 = T/ 4 x 4
T = 16 years/
Hence, the answer is (2) 16 years.
