In uneven cash flow, ‘IRR’ is an abbreviation of an

internal rate of return
international rate of return
intrinsic rate of return
investment return rate

The correct answer is A. internal rate of return.

Internal rate of return (IRR) is a measure of the profitability of an investment. It is the rate of return that an investment is expected to earn, given the initial investment and the expected cash flows.

IRR is calculated by finding the discount rate that makes the present value of the cash inflows equal to the present value of the cash outflows.

IRR is a useful tool for comparing different investment options. It can also be used to determine whether an investment is worth making.

The other options are incorrect.

  • Option B, international rate of return, is not a valid term.
  • Option C, intrinsic rate of return, is a similar concept to IRR, but it is calculated differently.
  • Option D, investment return rate, is a general term that could refer to any measure of investment profitability.
