effective annual rate is 6.16 %

to find out

effective annual rate

solution

we know formula for annual effective rate of interest is

rate of interest = $(1+ r/n)^{n}$ -1

put here all value

rate of interest = $(1+ 0.06/10)^{10}$ -1

rate of interest = $(1+ 0.06/10)^{10}$ -1

rate of interest = 0.061646

so effective annual rate is 6.16 %
