Consider a disk with a block size B $=1024$ bytes and a block pointer P $=12$ bytes. Suppose, file has r $=69632$

EMPLOYEE records of fixed length.

Each record has following attributes:

$$ First$\_$name $(60$ bytes$)$;

$$ SSN $(18$ bytes$)$;

$$ Dnumber $(18$ bytes$)$;

$$ Home$\_$address $(80$ bytes$)$;

$$ Contact$\_$phone $(20$ bytes$)$;

$$ BDate $(16$ bytes$)$;

$$ Gender $(2$ byte$)$;

$$ Job$\_$code $(8$ bytes$)$;

$$ Salary $(8$ bytes$)$;

$$ Additional $2$ bytes are used as a deletion marker.
