Question

BlackTom AI · Accepted Answer

The question asks for the formula to calculate the yield percentage.
Option a: 'None of the given choices' would be true only if none of the listed formulas were correct. Since one option actually matches a standard yield-style expression, this statement is not accurate.
Option b: '(EP/AP) *100' presents the ratio of EP to AP multiplied by 100, which corresponds to yield as a percentage in several financial and cost-accounting contexts where EP represents the end price (or ending value) and AP the initial price (or amount invested). This form expresses how much of the initial amount is recovered per unit, expressed as a percentage, and aligns with the provided correct answer field.
Option c: '(AP-EP)*100' computes the absolute difference between AP and EP, scaled by 100, effectively giving a profit difference in percentage terms if AP is the initial amount and EP is the ending amount, but it expresses profit magnitude rather than the yield ratio relative to the investment. This is not a standard yield percentage formula.
Option d: '(AP/EP)*100' inverts the ratio, comparing AP to EP rather than EP to AP. This does not represent yield percentage and can give misleading values depending on which is larger, so it is incorrect for yield percentage.
In summary, the only expression that matches a conventional yield-percentage form among the options is '(EP/AP) *100' (Option b). The other choices either invert the ratio or describe a difference in value rather than a proper yield ratio, or claim none of the options, which is false given that Option b is appropriate.
