The instruction pipeline of a RISC processor has the following stages. Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Writeback (WB). The IF, ID, OF and WB stages take 1 clock cycle each for every instruction. Consider a sequence of 100 instructions. In the PO stage, 40 instructions take 3 clock cycles each, 35 instructions take 2 clock cycles each, and the remaining 25 instructions take 1 clock cycle each. Assume that there are no data hazards and no control hazards. The number of clock cycles required for completion of execution of the sequence of instructions is

Question
The instruction pipeline of a RISC processor has
the following stages. Instruction Fetch (IF),
Instruction Decode (ID), Operand Fetch (OF),
Perform Operation (PO) and Writeback (WB).
The IF, ID, OF and WB stages take 1 clock cycle
each for every instruction. Consider a sequence
of 100 instructions. In the PO stage, 40
instructions take 3 clock eveles each, 35
instructions take 2 clock cycles each, and the
remaining 25 instructions take 1 clock cycle
each. Assume that there are no data hazards
and no control hazards.
The number of clock cycles required for
completion of execution of the sequence of
instructions is
