The correct answer is A. Rs. 1740.
The annual equipment cost of the machine is the annual amount of money that must be paid to recover the cost of the machine, including interest. This can be calculated using the capital recovery factor (CRF), which is a factor that takes into account the interest rate and the number of years of the loan.
In this case, the CRF is 0.174, the interest rate is 8%, and the number of years is 8. Therefore, the annual equipment cost of the machine is:
Annual equipment cost = CRF * Cost of machine / (1 – (1 + CRF)^-n)
= 0.174 * 20000 / (1 – (1 + 0.08)^-8)
= 1740
The other options are incorrect because they do not take into account the CRF.
