Logical address is divided into two parts:

1. Page number: N bits

2. Page offset: 2^N bits

Physical address = page base addr + page offset
If we have the follow page table:

page number block number
0 1
1 3
2 5
3 7

And the Page size is 1kb, the 13 bits logical address is 010 0 000 010 100(p=2,d=20)
Answer:
Because we can get page 2 maps to 5,so the physical address is

5*(1kb) + 20 = 1 010 000 010 100
