In MS Excel, the Goal Seek tool is used to
Answer: A
Correct answer: find the input value needed to produce a desired formula result
Goal Seek, under What-If Analysis on the Data tab, works a calculation backwards: given a formula and a target result, it finds the input value that produces it. It takes three arguments - the cell containing the formula, the value it should reach, and the single cell to change - and then adjusts that cell iteratively until the target is met. A typical use is finding the sales figure needed to hit a profit target, or the interest rate that gives a required repayment. Its limits define when to use something else. It changes exactly one input, the changing cell must be a constant rather than a formula, and it finds an approximate numerical solution rather than an exact algebraic one. For several inputs at once, or for constraints and an optimum rather than a target, the Solver add-in is the tool. Data Tables and Scenario Manager, on the same menu, explore what happens when inputs vary rather than solving for one.
