Question

How much time will be required for a Sum of money to double itself at 61⁄4% per annum Simple Interest? *​

Answer 1

Answer:

6.5 year

Step-by-step explanation:

Let the principal is 100 Rs.

So, s.i will be 100.

Rate = 61/4%

Time = s.i x 100/ principal x rate

Time =( 100 x 100)/(100 x 61/4)

Time = 100 x 4/61 =400/61

Time = 6.5 year
