Am i right?

Question

Answer 1

Here the order is defined for leaf node of B+ tree as : 

Maximum no of <key , record ptr > pair in leaf node

So let that p , so we have :

         p*(key size + record ptr size) + block ptr size <= 512

 ==>  p*(16) + 6 <= 512

==>   p  <= 506 / 16

==>   p  <= 31.625

But we have 32 now it will exceed maximum block capacity which is not allowed.

Hence p = 31 is correct answer..
