Relative Addressing Mode
Consider 3-word long jump instruction designed with PC-relative addressing mode, stored in the memory with a starting address of (2000)$_{10}$. Address field of an instruction contains (4000)$_{10}.$ Which of the following statements are true in the instruction ... where operand is stored, then how we can we assign it to PC? PC should be 2003 at the end of execution right?

Applied Test Series
Consider a processor that includes a base with indexing addressing mode. Suppose an instruction is encountered that employs this addressing mode and specifies a displacement of 1970, in decimal. Currently the base and index register contain the decimal numbers 48,022 and 8, respectively. What is the address of the operand?
