From the given info,
Simple as well as compound interest ( as compounded annually) for the first year will be 550/2= 275.
in the Second year, this interest i.e. 275 generated ( compound interest) the additional interest i.e. 605-(275+275)=55
No, interest 55is generated by 275 in one year is ONLY at 20% rate ( i.e. (55/275)*100).
