Chapter 4: Analyse Data using Scenarios and Goal Seek

1️⃣ Goal Seek

Purpose: Find the input value needed to get a desired output.

  • Example: You want your profit to be ₹5000, and you know the formula Profit = Sales – Cost.

  • Goal Seek adjusts Sales automatically to reach that profit.

How to use Goal Seek in LibreOffice Calc:

  1. Go to Tools → Goal Seek.

  2. Set Cell → The formula cell you want to reach a target (e.g., C5 = Profit).

  3. To value → Desired result (e.g., 5000).

  4. By changing cell → The input cell Calc can adjust (e.g., B5 = Sales).

  5. Click OK. Calc finds the required input.

Exam Tip:

  • Know the steps and purpose.

  • Example questions may ask: “Use Goal Seek to find required sales to reach target profit.”

2️⃣ Scenarios

Purpose: Compare multiple “what-if” situations without changing original data.

Example:

Sales Cost Profit
1000 600 400

  • Scenario 1: Profit when Sales = 1000

  • Scenario 2: Profit when Sales = 1200

Steps in Calc:

  1. Go to Tools → Scenarios → Add.

  2. Name the scenario and enter values.

  3. Switch between scenarios to see different outcomes.

Real-life Use: Budget planning, forecasting sales, financial decision-making.
