Compute the yield rate for this year by: (1) The exact method (2) The dollar weighted method and (3) By assuming that all contributions and withdrawals were made on July 1.

Suppose in problem 2 above that the balance on May 1, before the $30,000 deposit, is $106,000 and that the balance on November 1, before the $42000 withdrawal is $140,000. Compute the yield rate for this account using the time weighted method
