Blocking factor for data blocks= 1024/100=10 records per block
blocking factor for index blocks=1024/(2+8)=102 records per block
Total index entries= total data records=10000
therefore,total blocks required in level 1= 10000/102=99
level-2: total blocks=99/102=1
therefore , total no of blocks required in multilevel indexing=(99+1)+1=101
