A block can hold either $12$ records or $42$ key pointers .A database contains $96$ records , then how many blocks are required to hold the data file and the dense Index?

a). $10$

b). $12$

c). $11$

d). $13$

No of blocks for record = 96/12 = 8

For indexing = ceil(96/42 ) = 3

Hence,

So total no of blocks = 8+3 = 11
