Suppose a computer system has a 256Bytes virtual memory and a 128Bytes physical memory, the virtual memory has 8 pages and the size for each virtual page is 32 bytes; the physical memory has 4 page frames and each page frame include 32 bytes (byte, e.g. P3Of0, is just for assumption). The TLB (Translation Lookaside Buffer) and Page Table are given and illustrated in the figure as below:

a. What is the value stored at virtual address 0x2E in the physical memory?

b. What is the value stored at virtual address 0x76 in the physical memory?
