• Consider the following situation :
  A bank offers two types of savings accounts, Type A and Type B. For the Type A account, the bank pays a dividend on the account balance at the end of each quarter. The balance can be insured. The insured amount gets 8'750/o annual interest. The uninsured amount gets 5'00o/oa annuli interest. For the Type B account, dividends are paid monthly
  on an average daily balance for that month. No dividend is paid for a balance below Rs. 2,000,/-, otherwise 5% interest is paid on the first Rs. 5,000/-, 5'5%o on the next Rs. 20,000/- and 7o/o over Rs. 25,000,/-.
