Answer:
Tuesday
Explanation:
In order for a bank to pay a check, it must be passed on before receipt. Since Falls River Bank uses deferred posting, and the check was presented after the cutoff hour, it will be considered received the next business day. in this case the next business day is Monday. Then the bank has two business days to return a check.
If the bank is not going to pay the check and return it, it must do it before Tuesday at midnight.
