.

There are two factors in this problem that cause raising the interest.


One factor is the ratio of time periods  24%2F16 = 3%2F2.


The other factor is the ratio of initial deposits  6500%2F4000 = 65%2F40 = 13%2F8.


Therefore, the interest in the second case is  20.80%2A%283%2F2%29%2A%2813%2F8%29 = 50.70.    ANSWER
