Question

a sum taken for 1&1/2 years at 8% per annum is compounded half yearly .
​

Answer 1

Answer:

When a sum is taken for 1 &1/2 yrs at 8% per annum compounded half-yearly then the rate of interest is 4% per half-year & the time period is 3 half-years.

We know that when the interest is compounded half-yearly then the given time period is doubled and the rate of interest is halved i.e., the time is multiplied by 2 and the interest is divided by 2.  

Here we are given  

The rate of interest, R = 8% p.a.

Time period, n = 1 years = years

Since the interest has to be compounded half-yearly .

Therefore,

Rate of interest, R =  = 4% per half-year

And,

Time period, n = 2 = 3 half-years
