Question

Find the time periods and rate for a sum taken at 8% per annum for 11/2 years compounded half yearly.

Answer 1

We have interest rate 8 % per annum for (11/2) Years

=> Its compounded half Yearly. In compounded half yearly, the rate percent is divided by 2 and the number of years is multiplied by 2. Example if Time is 2.5 years and Rate is 4% so time became 5 years and Rate is 2% in Compounded Half Yearly.

So,  

Time period (t) = 2 (11/2) = 11 Years

And Rate (r) = (1/2) of 8% = 4 %

Answer 2

Answer:

Here compounded half yearly(6 months).so n=2 times for a year . n should be multiplied by time given and n should be divided by rate of interest . Hence Time periods= 11/2× 2=11 Rate=8/2=4%
