Consider a file of 16384 records. Each record is 32 bytes long and its key field is of size 6 bytes. The file is ordered on a non-key field and the file organisation is unspanned. The file is stored in a file system with block size 1024 bytes and the size of a block pointer is 10 bytes. If the secondary index is built on the key field of the file and a multi-level index scheme is used to store the secondary index, then the numbers of first-level and second-level blocks in the multi-level index are respectively
