(D) 0.625 %

Step-by-step explanation:

We have given effective rate of interest r = 7.5%

(a) Annual rate of interest will be equal to 7.5 %

(B) As we know that 1 year = 12 months

And interest is compounded semiannually

1 semiannual = 6 months

So semiannual rate of interest will be equal to %

(c) 1 quarter = 4 month

So number of period in an year = 3

So rate of interest quarterly %

(D) Amount when amount is compounded monthly '

So number of period in an year = 12

So rate of interest %
