How is RBV calculated?

The correct answer is determined by understanding that RBV, or Remaining Book Value, is calculated by taking the purchase cost of an asset and then subtracting the accumulated depreciation. This is because remaining book value reflects the net value of an asset as it ages, accounting for the decrease in value over time due to wear and tear or obsolescence.

When considering the other choices, they do not accurately represent how RBV is typically calculated. The first choice, which suggests subtracting depreciation from the sales price, does not align with how company assets are valued on the balance sheet. The second choice involves market value and adjustments, which is more reflective of a value assessment rather than a calculation of book value. Lastly, subtracting repairs from the asset value in the fourth choice does not factor in the systematic depreciation process that is essential for calculating RBV.

Therefore, using the purchase cost and deducting depreciation gives a clear and standard approach to calculating a remaining book value, which is why that choice is the most accurate.
