In your model, the page table entry is
address DIV page-size
the offset is
address MOD page-size
I don’t know if your addresses are hex or decimal. I will assume hex.
For your first example–20
page table entry = 0
page offset = 20
Your page table entry 0 maps to page frame 2 = 2 x page-size = 8K
Logical address 20 is then physical address 8K + 20.
Use the same process for the rest.
solved How to translate these logical addresses into physical addresses?
